Synthetic rubber is a material that plays an important role in many aspects of modern life. This type of rubber is crucial in various fields, from the automotive industry to the production of everyday consumer goods. Let's explore interesting information about synthetic rubber with Ru9 in the article below!
1. What is synthetic rubber?
Synthetic rubber is a type of flexible material created through the process of synthesizing natural rubber with various compounds such as Isoprene, Chloroprene, 1,3-Butadiene, and Isobutylene. This material is renowned for its excellent elasticity and high pressure resistance.
This type of synthetic rubber has replaced natural rubber in many applications, especially in the production of automobiles, hoses, tires, and many other products. The superior properties of synthetic rubber make it a preferred material in many different applications.

The development history of synthetic rubber is closely linked to World War II, when the US and many other countries researched and produced this material to meet wartime needs. Today, it remains a highly valuable resource, with annual production reaching millions of tons and significant value in the global market.
2. Basic properties of synthetic rubber
Synthetic rubber has special properties including strong adhesion, which helps synthetic adhesives bond tightly to various surfaces. At the same time, it demonstrates good tensile strength, not slipping from the surface even under pressure.
Synthetic rubber has relatively low grip and adhesion at temperatures above 40 degrees Celsius and lower anti-aging properties compared to natural rubber. However, it often has a lower cost and results in a final product with good elasticity and high durability.
Despite its many advantages, synthetic rubber also has environmental drawbacks. Synthetic rubber is difficult to decompose and can cause environmental pollution if not handled properly. This requires considering the advantages and disadvantages of this type of material in its use and production.
3. Common types of synthetic rubber materials
3.1. Buna Rubber (1,3 Butadiene)
The most common type of synthetic rubber is Polyisoprene, created by polymerizing isoprene. Chloroprene is another variation, produced from 2-Chlorobutadiene. Nitrile rubber is made from Cyanobutadiene or 2-Propenenitrile and Butadiene. Other variations are formed from combinations of different monomers and catalysts, creating specific properties for each type.
3.2. PU Plastic
Compared to other types of synthetic rubber, Polyurethane (PU) rubber stands out for its thermoplasticity and flexibility. This makes PU easier to mold than conventional synthetic rubbers.
The structural stability of PU is maintained through crystalline bonds. Meanwhile, SBS block copolymer uses an amorphous domain to create elasticity.

3.3. Silicone
Silicone rubber is an inorganic polymer, resistant to both very low and very high temperatures. It is often used for catheters and medical devices. However, its tensile strength is lower than that of other synthetic rubbers.
4. Distinguishing natural rubber and synthetic rubber
There are important differences between natural rubber and synthetic rubber:
- Origin: Natural rubber comes from natural rubber latex. In contrast, synthetic rubber is made from various chemicals.
- Characteristics: Natural rubber typically has better elasticity and is therefore often more expensive. Natural rubber is also safer and decomposes more easily in the environment.
- Molecular structure and composition: Natural rubber has a molecular structure primarily of cis-1,4 isoprene and contains proteins, fatty acids, phospholipids, and other natural components. Synthetic rubber can contain different isomers and does not have the natural components of natural rubber.
5. Prominent applications of synthetic rubber
Both natural and synthetic rubbers have many similar applications. They are used in manufacturing, medical, construction, mechanical engineering industries, and mattress production.
Products made from synthetic rubber are increasingly replacing natural rubber due to economic benefits. Currently, many families in Vietnam use mattresses made from synthetic rubber to ensure good sleep for their loved ones.
