In life, we often hear about ABS plastics. ABS plastics are used in electronic appliances and building materials. For example, we often use washing machines, televisions, refrigerators, computers, copiers, and many other electronic appliances that are used in our daily lives. ABS plastic, then what is ABS plastic? Let us learn more about it.
ABS plastic profile
ABS is a copolymer of acrylonitrile Acrylonitrile (23 to 41%), Butadiene Butadiene (10 to 30%), and Styrene Styrene (29 to 60%). The English name is Acrylonitrile-Butadiene-. Styrene, abbreviated as ABS.
ABS manufacturing methods are divided into two kinds of mixing method and grafting method, mixing ABS was first developed by the American Rubber Corporation in 1945, and the grafting method ABS was first synthesized by the United States Marbon company in 1954. Synthetic ABS has four grades: medium punching, high punching, ultra high punching and heat resistant.
The general proportion of the three monomers in the ABS copolymer is 20:30:50, so long as the proportion of the three, the polymerization method, and the size of the particles are changed, a series of ABS varieties having different impact strength and flow characteristics can be produced. For example, increasing the content of butadiene components can increase the impact strength of ABS, but the hardness and flowability will decrease, and the strength and heat resistance will deteriorate. If the content of butadiene in ABS reaches more than 50%, it is called high rubber powder and is often used for toughening modification of ABS and PC/ABS.
ABS was originally developed on the basis of PS modification. Due to its unique advantages of toughness, rigidity, and hardness, its usage is comparable to that of PS, and its application range has far surpassed that of PS. Therefore, it has become a kind of plastic that is independent of PS. In the early stages, ABS was divided into engineering plastics, but with its rapid development, the output soon approached its parent PS. Therefore, from 2000 onwards, it was classified as a general-purpose plastic and became the fifth-largest general-purpose plastic variety.
