Many people have heard of ABS Plastic Material more or less, especially for engineers in mechanical structure, molds, materials, etc. Most of the plastic products in our lives, such as all kinds of household Electrical products, 3C digital products, printers, computer monitors, etc., all use ABS as a large number of shell materials. As for why ABS is so widely used, it is because it has a very high cost performance.
Although ABS is a very common and common Plastic Injection Material, various aspects of its introduction are available online, but I still want to re-summarize and deepen the understanding of ABS, and also hope to help some readers have some differences in ABS. Get acquainted.
The full name of ABS is acrylonitrile-butadiene-styrene where A stands for acrylonitrile, B stands for butadiene, and S stands for styrene. It is a copolymer composed of these three monomers. Its molecular formula is as follows.
It can be seen from the full name or molecular formula that one of the monomers: styrene, is actually the monomer of polystyrene PS. PS, the Plastic Material itself, has good transparency, colorability, electrical insulation and fluidity. And other advantages, but at the same time its shortcomings are also obvious, brittle, easy to crack, low impact strength, poor heat resistance. Although PS has a large output and a low price, it is one of the five general plastics (PE, PP, PVC, PS, ABS). Obviously, before ABS appeared, there was no cost-effective material that could be applied on a large scale. In terms of daily products, however, among the five major general-purpose plastics, the value of PS transformation is greater. Of course, this is a story from now on.
All, ABS Plastic Material was originally developed on the basis of PS modification. Due to its unique advantages of rigidity, toughness and hardness, its dosage is equivalent to PS, and its application range has far exceeded PS, so it has become a plastic independent of PS. Variety. In the early days, ABS was classified as engineering plastics, but with its rapid development, the output quickly approached its parent PS. Therefore, it has been classified as general-purpose plastics since 2000, becoming the fifth largest general-purpose Plastic variety.
