Polypropylene homopolymer (PPH)

Polypropylene is part of polyolefins, thermoplastic materials with a wide circulation among products that are made by injection. It is an easy to process material with an average impact resistance, high structural resistance and also a resistance to an impressive range of chemicals. PP is processed mainly by injection, but also by extrusion – thermo-forming. It takes the form of opaque cylindrical granules.

The types of polypropylene resulted can be:

• homopolymers with no more than 5 % of other olefins;
• co-polymers with a content of 2-50 % of other olefins;
• modified co-polymers (grafted);
• polypropylene compositions with a minimum content of 50% polypropylene in which other additives are included.
