Overview
ABS is a terpolymer made from acrylonitrile, butadiene and styrene. The resin has good resistance to impact at low temperatures, high surface hardness, good resistance to chemicals and good electrical properties. ABS has varied levels of glosses. ABS with low-level gloss can be used to meet the special requirement of extensive application of leather-like surface in information technology. ABS is produced by Dow Chemical’s Bulk process. As no soap-based additives used in emulsion polymerization, the contents of impurities in ABS resin are low and particularly the contents of heavy metals are extremely low. The product is pure white and free of peculiar smell. It is the safest and healthiest ABS product currently available in the market.
Application
ABS is largely used in the production of components and parts of electrical household appliances and equipments, including the shells, linings and spare parts of TV sets, recorders, refrigerators, washing machines, air conditioners, water dispensers, telephones and electric fans, etc. It can also be used to make gears, impellers, bearings, handles, pipes and panels used in the machinery industry. It is also used in the automobile industry to make dashboards, splashboards and armrests. ABS is also widely used in the production of cases, bags, office equipments, duplicating machines, toys, food packaging vessels and furnitures. Products made from ABS can be re-processed through galvanization, welding and coating to make ornaments as substitutes of metals.
Package, Storage & Transportation
The resin is packaged in kraft paper bags and the net weight is 25Kg/bag. The resin should be stored in well-ventilated and dry warehouses and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive or flammable substance is strictly prohibited.
