Polyvance announced the availability of two welding rod profiles for the R18 glass fiber-reinforced polypropylene welding rod.
R18 is a polypropylene reinforced with 15 percent long glass fiber. This material is used on radiator supports and many other underhood components. It is also used on late model Sea Doo personal watercraft hulls. The identification symbol is PP+GF, usually with a number behind the “GF” indicating the weight percentage of glass fiber in the blend.
Polyvance added two new profiles to the R18 family – the -02 profile 3/16” diameter round rod and the -05 profile 5/8” wide ribbon. These profiles join the existing -04 profile 3/8" wide ribbon. R18 is only available in black. It is designed to be used to reinforce the backside of welds on unreinforced PP materials.
