Polypropylene (PP)

Polyolefins include both polypropylene (PP) and polyethylene (PE). The two best-known types of polyolefin have in common a low density of less than 1g/cm³ and the chemical resistance described above.

Polypropylene has 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 harder PP can be clearly seen on the surface in particular.

PP is clearly inferior to PE in terms of wear resistance. Due to its typical chemical resistance, PP is particularly suitable for components in systems and equipment in the chemical and galvanising industries as well as in laboratory and pump technology. PP can be welded and can be thermally moulded.
