Material Notes:
Polypropylene 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.Propertieslow weighthigh heat resistancehigh tensile strengthhigh surface strengthhigh chemical resistancelow oxidation resistancelow abrasion resistancebrittle in the coldnessHF-welding not possiblenatural color is not weather resistantApplicationspumpsvalvesgasketssupporting standsspacer for the platingparticles for toys PP-30GF has 30% glass fiber reinforcement with improved dimensional stability, high stiffness, and high resistance to heat.
