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 temperature ranges between +5 °C and +100 °C.

Properties

 low density
 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 for the coating industry, spacer for the plating, particles for toys.
