Homopolymeric Polypropylene has a very low density and a very high heat deflection temperature in the group of polyolefins. The chemical resistance is very high, but the oxidation resistance is in the lower range. Due to the very low dielectric loss factor, high-frequency welding is not possible. However, all other appropriate welding procedures should work without problems. The continuous operating temperature for PP in natural colour ranges between -22 °F and approximately +190 °F.
