PP
Polypropylene
PP is a lightweight, chemically resistant thermoplastic with good weldability. The material has the lowest density among common technical plastics (0,91 g/cm³) and resists most acids, bases and solvents. PP is widely used in the chemical process industry for tanks, pipes and valves, and is FDA-approved in standard configuration. The material can be welded with hot air and extrusion welding, which makes it possible to build leak-proof tanks and containers. We have PP in plates, round rods, pipes and weldable profiles.
