POLYPROPYLENE
PolypropylenE (PP)
Polyolefins include both polypropylene (PP) and polyethylene (PE). The two best-known polyolefin types have in common the low density of less than 1g/cm3 and the chemical resistance as already described.
Polypropylene has a considerable strength and hardness for polyolefins, but tends to become brittle at low operating temperatures and is then correspondingly sensitive to impact. The difference between the softer PE and the hard PP is particularly well visible on the surface.
In terms of wear resistance, PP lags well behind PE. Due to its typical chemical resistance, PP is particularly suitable for components in systems and devices in the chemical and galvanic industries as well as in laboratory and pump technology. PP can be welded and thermally deformed.
Main features
