GEHR Plastics PP-30GF Polypropylene, 30% Glass Fiber
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene with 30% Glass Fiber Filler
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. Properties low weight high heat resistance high tensile strength high surface strength high chemical resistance low oxidation resistance low abrasion resistance brittle in the coldness HF-welding not possible natural color is not weather resistant Applications pumps valves gaskets supporting stands spacer for the plating particles for toys PP-30GF has 30% glass fiber reinforcement with improved dimensional stability, high stiffness, and high resistance to heat.
