ABS material is a graft copolymer of three monomers: acrylonitrile (Acrylonitrile), 1,3-butadiene (Butadiene), and styrene (Styrene). Its molecular formula can be written as (C8H8-C4H6-C3H3N)x, but in fact it is often a mixture of graft copolymer containing butadiene and acrylonitrile-styrene copolymer, in which acrylonitrile accounts for 15% to 35%, butadiene accounts for 5% to 30%, and styrene accounts for 40% to 60%. The most common ratio of ABS in the emulsion method is A:B:S=22:17:61, while the native The molding temperature for ABS plastics is 180-250°C, but it is best not to exceed 240°C, when the resin will decompose.
The biggest application areas of ABS resin are automotive, electronic and electrical appliances, building materials and DIY fabrication fields. The use in the automotive field includes automotive instrument panels, exterior body panels, interior trim panels, steering wheels, sound insulation panels, door locks, bumpers, ventilation ducts and many other parts. In the electrical field
ABS is widely used in electronic appliances such as refrigerators, TV sets, washing machines, air conditioners, computers, copiers, etc. For building materials, ABS pipes, ABS sanitary ware and ABS decorative panels are widely used in the building materials industry and for DIY, such as model airplane wings. ABS
is also widely used in packaging, furniture sports and recreational goods, machinery and instrumentation industries.
The important goals pursued for automotive interiors include aesthetics, low odor, mechanical properties, heat resistance, weather resistance, etc. Automotive materials can meet the requirements for the use of various interior components, materials with the following conditions:
1. good flowability
2. Excellent impact resistance
3. Easy processing and molding
4. Easy to color and paint
5. low odor
6. Good corrosion resistance
7. Matte effect
