What is ABS plastic? Many people don't know. What are the characteristics of GRS certified ABS plastic products?
ABS is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It is also easy to process, product size is stable, and good surface gloss. It is easy to paint and dye. It can also be used for secondary processing such as metal spraying, electroplating, welding, hot pressing and bonding. It is widely used in machinery, automobile and electronic appliances It is a kind of thermoplastics engineering plastics with wide application.
ABS material is also known as ABS engineering plastics. Its appearance is opaque and ivory colored. Its products can be colored and have high gloss. The relative density of ABS is about 1.05, and the water absorption is low. ABS has good adhesion with other materials and is easy to be printed, coated and plated. The oxygen index of ABS is 18-20, which belongs to flammable polymer. The flame is yellow, with black smoke and special odor.
ABS resin is a yellowish solid with certain toughness, and its density is about 1.04-1.06 g / cm3. It has strong corrosion resistance to acid, alkali and salt, and can also tolerate organic solvent dissolution to a certain extent. ABS resin can perform normally in the environment of - 25 ℃ - 60 ℃, and has good formability. The surface of the products processed is smooth, easy to dye and electroplate. Therefore, it can be used in household appliances, toys and other daily necessities. The common Lego building blocks are ABS products. ABS resin can be blended with a variety of resins to form blends, such as PC / ABS, ABS / PVC, PA / ABS, PBT / ABS, etc., resulting in new properties and new application fields. For example, transparent ABS resin can be produced by mixing ABS resin with PMMA.
ABS resin is the most widely used polymer with the largest output at present. It combines the various properties of PS, San and BS organically, and has excellent mechanical properties of toughness, hardness and rigid phase balance. ABS is a terpolymer of acrylonitrile, butadiene and styrene. A represents acrylonitrile, B represents butadiene and s represents styrene.
ABS has good electrical insulation and is hardly affected by temperature, humidity and frequency. It can be used in most environments. At the same time, it is a kind of thermoplastic with excellent processing performance. It can be processed by general processing methods, and is widely used in automobile, electronic appliances and building materials. The shell of mobile phone is also made of ABS engineering plastics.
