Polycarbonate is hard as nails and is commonly used on bumpers on older model Ford Taurus, Mercury Sables, and Ford Aerostar mini-vans. It is also used on Hyundai bumpers and Mercedes bumpers. Saturn door panels may also be welded with polycarbonate since they are made from Pulse, which is a polycarbonate blend. The generic name is polycarbonate but the "brand names" for polycarbonate are Xenoy and Lexan. This package contains 10 ft. (3 m) of polycarbonate plastic welding rods. Each rod measures 12 inches (30 cm) long and is 1/8th inch (3 mm) in diameter..
