Plastic Welding Rods
Plastic Welding Rods
Plastic welding rods are the consumable filler material used to join two plastic parts during hot-air welding. The single most important rule: the rod must be made of the same plastic as the parts you’re joining. Welding PVC with a polypropylene rod, or HDPE with a PEMD rod, will produce a weak weld that fails under stress.
The Plastic Welding Tools range covers every common thermoplastic — manufactured by Techspan from virgin (un-recycled) material to ensure consistent flow and bond strength:
PP (polypropylene) — for polypropylene tanks, automotive battery boxes, ducting, and chemical fabrications.
PE-HD (high density polyethylene) — for HDPE pipe, large water tanks, geomembrane and landfill liner work.
PE-MD (medium density polyethylene) — for vehicle bumpers (most modern bumpers are PEMD), splash shields, and softer polyethylene products.
PVC — for rigid PVC plumbing, signage substrate, and cafe blinds.
ABS — for ABS panels, automotive trim, and 3D-printed-part repairs.
PP/EPDM — for thermoplastic-rubber blends used in vehicle interior plastics.
Rods come in standard 3 mm, 4 mm and 5 mm round profiles for most welding, plus triangular and rectangular profiles for fillet and butt-weld applications respectively. Common pack sizes are 50 m rolls for repair work and 400 m bulk rolls for production fabrication.
Not sure what plastic you’re welding? Our plastics identification guide walks you through the burn test, float test, and recycling-code lookups that will tell you whether you’ve got PP, HDPE, PEMD, PVC or ABS in hand.
