In the market today, synthetic rubber is a type of rubber that is being used a lot in many industries, increasingly popular and widely. Instead of using expensive natural rubber, customers are gradually moving towards this type of rubber because it has superior properties than natural rubber. And do not let you wait long, we will together find out what synthetic rubber is and what features they have that make customers choose to use this product more and more.
1.What is synthetic rubber?
Synthetic rubber is a man-made plastic that has elastic properties and can withstand great pressure which leads to being able to change its original shape but still be able to recover.
2. How is synthetic rubber made?
This rubber is produced by condensation of single-celled structures including isoprene, 1.3 - butadiene, chloroprene and isobutylene with a small percentage of isoprene for chain linkage. In which these single structures can be mixed in certain proportions that they want to produce a copolymer, resulting in structures with different properties that can be applied to the items. intended use is different.
3. What's the properties of neoprene?
- This rubber has high adhesion, outstanding shear strength. And when in the case of strong pull on the sides, this rubber will not slip off the surface.
- This type of rubber has a relatively low adhesion and adhesive strength when in temperatures up to about 40 degrees C.
- Better anti-aging than natural rubber, products made from this rubber all have features such as good elasticity, high durability and very smooth surface finish. , especially safe for users.
- This type of rubber has a cheaper price than natural rubber, so this rubber will be very suitable for our country's per capita income today when there is a need to use it.
However, this type of rubber has a disadvantage that when it is no longer used, it is difficult to decompose in the natural environment, if not handled properly, it will easily cause environmental pollution.
4. History of synthetic rubber?
- In the 1890s, all kinds of road vehicles began to use pneumatic wheels mainly because of that, the demand for rubber increased rapidly. But because of political problems, the price of natural rubber fluctuates greatly.
Recognizing these problems in 1879, Bouchardt successfully fabricated synthetic rubber from isoprenic polymerization that began in the process of creating a rubber that performs like natural rubber. The price is cheaper than the large supply to meet the market.
- In that work Germany was the first country that succeeded in producing synthetic rubber on a commercial scale. It took place in the first world war when the demand for natural rubber was not met enough, the supply was too little. So Germany created synthetic rubber based on the polymerization of butadiene different from the type of Bouchardt. This is the work of Russian scientist Sergei Lebedev. And when the war ended, this rubber was replaced by natural rubber. But scientists do not give up but continue to research to find the more superior synthetic rubber that can meet the set needs. As a result, scientists have successfully invented Buna S rubber (styrene-butadiene rubber). This is a product created from the polymerization of butadiene and styrene.
5. What is the application of neoprene?
Due to its similar characteristics as natural rubber, but with lower cost, this rubber has been applied in a number of industries such as manufacturing, construction, mechanics, medicine, and cushion production. synthetic rubber and many other industries.
- Applications in the transport industry such as impact resistant rubber, speed bumpers, ..
- In the construction industry such as rubber bearings, bridge and road expansion joints, ...
- In the irrigation and hydropower industry as rubber gaskets, rubber seals, ...
- In industries such as making rubber mats, rubber wheels, rubber rollers, tires, rubber pipes ...
- In the medical industry is made into rubber buttons, ...
6. How to differentiate neoprene from natural rubber?
- First we will consider the origin: natural rubber will be made from the latex of the rubber tree, while synthetic rubber they are made from synthetic materials from a variety of chemicals.
- Second, we will consider the characteristics: natural rubber because it is a product made from natural materials, they are very safe for the health of consumers and can decompose in the natural environment, but In contrast, synthetic rubber products are made from different chemicals such as so they are difficult to decompose in the natural environment.
- Third, we will consider their molecular structure and composition: natural rubber is structured as cis-1.4 isopren (over 98%) including ingredients such as proteins, phospholipides, fatty acids, ... Neoprene has structures that contain various isotopes such as cis-1.4, trans-1.4, isotope 1,2 or 3,4.
Here are all neoprene related information that I can supply to you. Hope that the article will help you better understand what neoprene is and as well as its characteristics or history. Hope the article brings great experiences to you. Thank you for following up on this article.
