POLYPROPYLENE (PP)

PP does not present stress-cracking problems and offers excellent electrical and chemical resistance, at higher temperatures. While the properties of PP are similar to those of Polyethylene, there are specific differences. They have a lower density, are translucent, tough, semi-rigid, offer higher rigidity and hardness.

HOMOPOLYMER (PP-PH)

Homopolymer (PP-PH) is the most widely utilized PPH, offering a high strength to weight ratio and is stiffer and stronger than co-polymer. Good chemical resistance and weldability allows this material to be used in many corrosion resistant structures.
Homopolymers provide varied set of properties to meet the market needs in packaging.
APPLICATIONS: Household goods, textiles, film, healthcare, and pipe, as well as applications in the automotive and electrical industries.

COPOLYMERS (PP-CP )

Polypropylene Copolymer (PPC) is a bit softer but has better impact strength, is tougher and more durable than PPH. Copolymer polypropylene tends to have better stress crack resistance and low temperature toughness, than homopolymer at the expense of quite small reductions in other properties.
APPLICATIONS: Pump components, impellers, casings, liners, covers, fume hoods and ducts, structural tanks for chemicals, industrial battery cases and Orthotics.
