Welding Rod in PPs white

PPs is flame retardant polypropylene and must not be confused with PPS, polyphenylene sulfide, which is a completely different material. PPs is a flame modified PP-H that meets building fire class B1. The additive makes the material heavier and slightly less impact resistant than standard PP-H.

The density is 0.95 g/cm³, the tensile modulus 1600 MPa and the yield strength 32 MPa. The elongation at yield is 8 percent and the notched Charpy impact strength 6 kJ/m². The ball indentation hardness is 70 MPa, Shore D 72 and the temperature range 0 to +100 °C.

The flame modification means the material burns slowly and goes out by itself. It is not approved for food contact.

PPs is used for structural parts, guards and interior fittings where high fire requirements apply, for example in vehicles, cabins and buildings. The material is machined with saw, mill and drill.

The flame modification can make the surface somewhat harder than standard PP-H, so sharp cutting edges and normal spindle speed are preferable. Welding is done with hot air or a welding rod.

This welding rod in PPs is white and is supplied in standard format, which suits hot air welding of sheets, tubes and parts. This welding rod in PPs in white is particularly well suited to repairs and making tight joints. Contact us if you want this welding rod in PPs in white adapted to your needs.
