Question

what are plastics?write note on compounding of plastic​

Answer 1

Plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects.

Compounding consists of preparing plastic formulations by mixing or/and blending polymers and additives in a molten state, these blends are automatically dosed with fixed setpoints usually through feeders/hoppers. It is mostly a blend of copolymers such as ABS, SAN, SMA etc. with additives such as anti-oxidants, UV-stabilizers and other value adding agents and sometimes a strengthening component is added such as glass fibre.
