Polyvance, in response to industry and customer demands, announced the availability of three welding rod materials.
R18 is a polypropylene reinforced with 15 percent long glass fiber. This material is used on some radiator supports and other support components. The R18 only comes in the -04 (3/8” wide flat ribbon) profile and can only be used with the nitrogen plastic welder. R18 is only available in black. It may be used to reinforce the backside of welds on unreinforced PP materials. The R18 is available in 30’ and 1-lb packs, No. R18-04-03-BK and No. R18-04-04-BK, respectively.
R19 is a high-density polyethylene reinforced with 15 percent long glass fiber. Although it hasn’t been used on passenger vehicles yet, it is seen in industrial applications. R19 is available in natural color only (non-pigmented) and in two profiles, -04 and -08 (corner rod). The corner rod is ideal for doing fillet welds in sheet fabrication. The part numbers are: -04 profile (3/8” wide), Nos. R19-04-03-NT, R19-04-04-NT; -08 profile (corner rod), Nos. R19-08-03-NT, R19-08-04-NT.
R20 is a blend of polycarbonate and ABS (PC+ABS), a rigid plastic that is used on some automotive exterior panels and underhood support panels. Currently the only available profile is -01 (1/8” round rod) and the color is white. It is available in 30’ and 1-lb packs, No. R20-01-03-WH and No. R20-01-04-WH, respectively.
