Material
PE/PP-like Polyurethanes
Vacuum-cast PE-/PP-like polyurethanes resemble injection-molded polyethylene (PE) and polypropylene (PP). Tough and lightweight, they are ideal for producing high-quality prototypes or small series of end-use parts. Our wide range offers a choice of properties, with various finishes available. For use with silicone molds.
