PP-polypropylene
Trade names: HOSTALEN PP…
Polypropylene- PP shows a high mechanical strength and a tensile strength, but a low notched impact strength. PP resists stress cracking and it is easy to weld. At minus temperatures it can get brittle. The chemical and electrical properties are very good. The continuous operating temperatures ranges between +5 °C and +100 °C.
Types:
- PP
- PP-30GF (30% glass fibres)
Properties:
- low density
- high heat resistance
- high tensile strength, high surface strength
