What is natural rubber? Structure, properties, and applications
Natural rubber is one of the most widely used materials in daily life due to its outstanding properties and high applicability. It is also a popular material for its durability, elasticity, and environmental friendliness. So, what is natural rubber? What are its advantages and disadvantages? How is it applied in practice? Let's find out in detail through the article below!
1. What is natural rubber?
1.1. Concept
Natural rubber is an elastic material produced entirely from the latex of rubber trees (Hevea brasiliensis), with the molecular formula (C5H8)n - which is a polymer mixture of isoprene.
Initially, natural rubber was in a liquid state. After the vulcanization process in 1839, it became more durable and elastic and was widely used in industry.
Besides the rubber tree, some other plant species can also produce latex, but they do not play a significant role in commercial production. During World War II, Germany attempted to exploit alternative sources, but this stopped when synthetic rubber was invented.
1.2. History of development
16th century: Natural rubber was discovered and used by the people of South America.
Centuries later: South America remained the main supplier but with limited production.
1876: Henry Wickham smuggled 70,000 rubber tree seeds from Brazil to England, then distributed seedlings to countries such as India, Sri Lanka, Indonesia, Singapore, and Malaya (now Malaysia).
1873: India experimented with rubber cultivation at the Calcutta Botanical Garden.
1902: India began commercial rubber cultivation in Thattekadu, Kerala.
1888–1911: Sir Henry Nicholas Ridley promoted rubber production in Singapore and Malaysia by developing efficient tapping techniques.
20th century: Natural rubber expanded to Africa, with major production centers in the Congo Free State, Liberia, and Nigeria.
Currently, natural rubber remains important in the global economy but is gradually being replaced by synthetic rubber.
1.3. Structure and chemical formula of natural rubber
Chemically, natural rubber is polyisoprene – a polymer of isoprene.
The structure of natural rubber consists of cis-1,4 isoprene monomer units linked together, forming a macromolecular chain. In addition, about 2% of the monomer units in natural rubber are linked in a 3,4 configuration.
Similarly, the plant resin Gutta-percha is also a polymer of isoprene but has a trans-1,4 structure, unlike natural rubber.
1.4. Physical properties
At low temperatures, natural rubber crystallizes, fastest at -25 °C and melts at 40 °C.
Density 913 kg/m³, glass transition temperature -70 °C.
Volume expansion coefficient 656 × 10⁻⁴ dm³/°C, thermal conductivity 0.14 W/m·K, specific heat capacity 1.88 kJ/kg·K.
Dielectric permittivity 2.4–2.7 (@1000 Hz/s), loss tangent 1.6 × 10⁻³.
Dissolves well in straight-chain, cyclic organic solvents, CCl₄, but insoluble in alcohol and ketones.
2. Natural rubber production process
2.1. Latex collection
The most common method is tapping: harvesters cut a spiral groove around the trunks of mature trees, which severs the latex vessels, allowing the white milky substance to flow out.
The cut is usually at an angle of about 30 degrees. To collect the exuding latex, a cup, bowl made of glazed clay, or a plastic bucket is often used.
2.2. Raw material quality control
After harvesting, the latex is inspected for quality using a photosensitive latex method. Next, the latex is transferred to specialized storage facilities with airy, clean, and hygienic cement floors. Here, workers sort and mix different types of latex according to technical standards and begin mechanical processing steps.
2.3. Mechanical processing
Natural rubber latex is separated into smaller blocks of 5-15kg via conveyor belts, making it easier to remove impurities and fit into the kneading machine. These blocks of latex are then put into a mixing tank for washing and then flattened. Finally, the latex is transferred to a combined shredding machine to break it down into a loose crumb form.
2.4. Thermomechanical processing
Tough latex needs to be converted into soft rubber through four processing steps including thermal oxidation, heat, chemical, and mechanical treatment by mixing with several other compounds. After being stacked into drying containers in specific quantities, the latex is hot-dried at approximately 150-200 degrees Celsius for 24 hours.
2.5. Weighing and pressing
Once the hot drying process is complete, the rubber is transferred to a sorting table to cool naturally before being weighed. The semi-liquid latex needs to be heated and measured using specialized equipment. Then, all the latex is fed into the press chamber, where it undergoes shaping and packaging in PE bags.
2.6. Packaging and preservation
PE bags containing natural rubber are lined with two layers of nylon mats, an inner translucent layer and an outer opaque layer.
3. Analysis of the advantages and disadvantages of natural rubber
3.1. What are the advantages of natural rubber?

Easily oxidized: Containing no preservatives, natural rubber is easily oxidized when exposed to the environment.
Waste treatment: The production process remains controversial due to the inability to thoroughly treat the generated waste.
3.3. Which is better, natural rubber or synthetic rubber?
Unlike natural rubber, which is 100% natural, synthetic rubber is produced by humans through the polymerization of monomers into polymers. Each type of monomer will create synthetic rubber with different characteristics.
So why, when natural rubber already exists, was synthetic rubber researched and created? Is synthetic rubber better than natural rubber? In reality, the two types of rubber have different advantages, and therefore they are also prioritized for different applications.
Overall, natural rubber possesses excellent elasticity, flexibility, antibacterial properties, and long-lasting durability. Therefore, it is best suited for making rubber mattresses – products that promote health and can be used for a long time.
On the other hand, synthetic rubber has better heat resistance, abrasion resistance, anti-aging properties, and weather resistance, so it is often applied in the marine industry, general industry, and the production of outdoor products, etc.
Therefore, to conclude whether natural rubber or synthetic rubber is better, it must be based on the needs and application area.

What is synthetic rubber? Structure, applications, and classification
Synthetic rubber is considered one of the world's most important inventions, thanks to its widespread application in many manufacturing fields. The popularity and value of this material are undeniable. So, what exactly is synthetic rubber and how is it manufactured? Let's explore in the following article.
1. What is synthetic rubber material?
Synthetic rubber is a type of rubber created by humans through the polymerization of monomer isoprene and isobutylene chains, along with a small amount of isoprene.
This rubber material is flexible, highly elastic, and widely used in many fields, especially in mattress manufacturing.
So, how does synthetic rubber differ from natural rubber? What was the reason for humans to create synthetic rubber?
As the name suggests, natural rubber is made from the sap of rubber trees. The sticky film from rubber latex droplets undergoes polymerization to form isoprene. Because it is made from natural raw materials, natural rubber is extremely safe, highly antibacterial, and environmentally friendly. However, the cost of this material is very high and it is becoming increasingly scarce due to the limited area of rubber forests on Earth.
To overcome the price disadvantage and meet the increasing demand of consumers, synthetic rubber was invented. This material possesses the outstanding advantages of natural rubber, such as high elasticity, good sound insulation, and heat resistance, but at a much lower price.
2. Synthetic rubber manufacturing process
The synthetic rubber manufacturing process involves many important steps, depending on the type of rubber selected. So, what is synthetic rubber made from and how is it created? Below are the typical processing and manufacturing steps for a type of synthetic rubber.
Step 1: Create and refine hydrocarbon mixtures derived from petroleum or coal.
Step 2: Naphtha – a flammable liquid hydrocarbon mixture, often used in gasoline and plastic production – is combined with natural gas to create monomers. These monomers will link together to form polymer chains. In synthetic rubber production, common monomers include styrene-butadiene (SBR), nitrile (NBR), and butyl (IIR).
Step 3: Chemical agents are used to link individual polymers, forming long polymer chains, which create the rubber material known as synthetic rubber.
Step 4: The rubber then undergoes vulcanization, in which accelerators such as sulfur are added to increase strength and elasticity, helping to transform the polymer into a stronger material.
Step 5: Finally, the rubber is molded into the desired shape and undergoes a quality control process to ensure it meets technical standards.
3. Is a synthetic rubber mattress better than a natural rubber mattress?
3.1. Is a synthetic rubber mattress good?
Synthetic rubber mattresses are made from synthetic rubber, primarily Polyurethane foam – a common and long-standing industrial material in the mattress manufacturing industry. This type of mattress has its own advantages and disadvantages, specifically as follows.
What are the advantages of synthetic rubber?
Low price
Synthetic rubber mattresses are an optimal solution for the material and cost limitations of natural rubber mattresses. With a composition mainly of chemical substances, this type of mattress has a reasonable price, suitable for a wide range of customers. Product prices vary, depending on factors such as brand, material, and size.
High elasticity
Elasticity is one of the important criteria when choosing a suitable mattress. Synthetic rubber mattresses stand out with their firmness and better elasticity compared to many other types of mattresses on the market. The special structural design of the mattress helps increase the contact area with the body, supporting even weight distribution, providing a soft feeling, and helping to achieve deeper sleep.
High durability and safety
Synthetic rubber mattresses have high durability due to their strong structure and tight chemical bonds, resisting sagging and air leakage, ensuring long-term use. The Polyurethane material is safe, limits dust accumulation, and protects health. In addition, the mattress provides good body support, especially suitable for people with lower back pain or bone and joint conditions.
Provides softness and comfort for users
Mattresses play an important role in supporting sleep and indirectly affecting health. A mattress that provides softness and comfort is considered a criterion for a quality product. Synthetic rubber mattresses, with their main component being synthetic chemicals, can adapt to body shape, are waterproof, and support blood circulation. Many users comment that the mattress is soft, reduces noise when turning over, provides a comfortable feeling, and helps them fall asleep more easily.
Disadvantages of synthetic rubber mattresses
Synthetic rubber mattresses were developed to replace natural rubber mattresses and are suitable for many customer segments. However, their durability and elasticity are still inferior to natural rubber mattresses.
In addition, because they are made from synthetic chemical raw materials, there are many low-quality mattresses on the market that can affect health. Therefore, users should research carefully before choosing a product.
3.2. Advantages and disadvantages of natural rubber mattresses
Natural rubber is the original material for developing and creating other rubber materials, so it certainly possesses excellent advantages to consider. So, what are the advantages and disadvantages of natural rubber mattresses?
Advantages
100% safe and benign: The natural origin gives natural rubber mattresses absolute safety. The mattress has excellent antibacterial and dust-resistant properties, is benign for all skin types and respiratory systems, including children. This is an ideal mattress for people with bone and joint pain, back pain, or children whose height is developing, thanks to its high elasticity and firm, stable surface.
High durability: The lifespan of a rubber tree can be up to nearly 100 years, so natural rubber mattresses often have a lifespan of up to 20 years while still maintaining product quality.
Environmentally friendly: Compared to rubber materials produced from petroleum, natural rubber mattresses with 100% natural origin are very environmentally friendly.
High breathability: The holes on the mattress surface allow air to circulate continuously. Therefore, natural rubber mattresses are famous for their excellent breathability and anti-mold properties. Natural rubber mattresses are very suitable for hot climates like ours.
Disadvantages of natural rubber mattresses
The only disadvantage of natural rubber mattresses is perhaps their high price due to the premium and scarce raw materials.
In addition, some customers have reacted that natural rubber mattresses often have a rather strong odor when newly purchased.
3.3. Should I buy a synthetic rubber mattress or a natural rubber mattress?
Each material has very clear advantages and disadvantages, and it can be said that these two types of mattresses complement each other. Therefore, depending on which criterion you prioritize, you will be able to determine whether a natural rubber mattress or a synthetic rubber mattress is suitable for you.
If you are environmentally conscious and prioritize material safety, or if you and your family have sensitive constitutions, then boldly invest in a natural rubber mattress.
If you want to buy a rubber mattress but your budget is limited, then a synthetic rubber mattress is the perfect choice for you. Although it is much cheaper, a synthetic rubber mattress still possesses the core advantages of a rubber mattress, such as high elasticity, long lifespan, etc.
In addition to the two materials mentioned above, you can also consider Memory foam, which is produced and integrated into Ru9's Foam mattress and Topper mattress topper product lines.
