Polyethene is a lightweight, durable thermoplastic with a variable crystalline structure. Widely used in vehicle plastic bumpers and trim.
Thermoplastic welding rods are widely used in the automotive industry for car bumpers and motorcycle parts. Ideal for use with Hot Air Plastic Welders and Nitrogen Plastic Welders.
Most manufacturers have a code on the bumper or part to help identify the plastics used. If no identification is present, then carry out a short weld test. If the repair sticks when fully cold, then you have a suitable match.
