| Beta-PPR™ RA7050 is a PP-RCT(1), a Polypropylene-Random-Copolymer with an enhanced Crystalline structure brought about by a special ß-nucleation and with an improved Temperature resistance. Proof of the excellent performance characteristics of Beta-PPR™ RA7050 is, for example, a categorised required strength (CRS) of 5 MPa at 70°C and 50 years in comparison to a value of 3.21 MPa for standard PP-R. The colour of Beta-PPR™ RA7050 is steel grey similar to RAL 7042. In general Beta-PPR™ RA7050 is intended to be used in applications for plumbing and heating, such as in-house hot and cold water pipes and fitiings, floor and wall heating systems and radiator connections.&& |
