ABS Plastic (Acrylonitrile – Butadiene – Styrene)
The polyolefin has turned out to be the most versatile of the plastic family, accounting for the continuing rapid increase in its use. Polypropylenes have better resistance to heat and resist more chemicals than do other thermoplastic plastics of the came cost. Also, polyproylenes have negligible water absorption and excellent electrical properties, and they are easy to process. Like other polyolefins, polypropylene plastics have excellent resistance to water and to water solutions, such as salt and acid solutions that are destructive to metals. They are also resistant to organic solvents and alkalis.
Apllications: .The greatest commercial uses for homopolymer PP are in fibers and filaments. PP plastic is also made into unoriented
and oriented films for packaging and is injection-molded into caps and closures, appliance components, and auto parts.
