Injection molded polypropylene
Webb3 feb. 2024 · PP has been produced industrially in larger batches since 1957. It is a thermoplastic material belonging to the groups of polyolefins. This means that PP plastic can be formed at higher temperatures. At room temperature or generally low temperatures, PP has material properties that are highly useful for many users: High chemical resistance WebbPolypropylene (PP) Thermoplastics Polypropylene This low cost resin in a homopolymer, copolymer, and random copolymer form is plastic injection molded by Rebling for many unique applications. Typical reasons for choosing polypropylene are cost; chemical resistance; electrical insulating properties; translucence and “live hinge” applications.
