Twin-Wall corner element in PP-C 2000x40 mm gray
PP-C, polypropylene copolymer, is the tougher version of polypropylene. C stands for copolymer, a version that is tougher and takes temperature swings better than the homopolymer. The material is softer than PP-H and keeps its impact strength even when it is cold.
The density is 0.91 g/cm³ and the modulus 1200 MPa. The yield strength is 23 MPa and the elongation at yield 7 percent. The notched Charpy impact strength is 45 kJ/m², the ball indentation hardness 50 MPa and Shore D 67. The dielectric strength is 52 kV/mm.
The temperature range runs from -20 °C to +80 °C in short term testing. The building fire class is B2. PP-C in natural is approved for direct food contact per FDA.
PP-C is used for tanks, vats, tubes, ventilation ducts, machine guards and parts exposed to impacts in the cold. The material is welded with hot air or a welding rod and can be sawn, milled and drilled with ordinary tools.
This twin-wall corner element in PP-C is gray and measures 2000x40 mm, which suits corners, end finishes and transitions in twin-wall structures. With the 2000x40 mm dimension and the gray surface you get a twin-wall corner element in PP-C that is particularly well suited to corner sections that have to match the other twin-wall sheets. Contact us if you want this twin-wall corner element in PP-C with the 2000x40 mm dimension and the gray surface adapted to your needs.
