Borealis RA7050-GN Polypropylene-Random-Copolymer for Pressure Pipe Systems
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene, Extrusion Grade
Material Notes:	RA7050-GN is a PP-RCT, 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 RA7050-GN is, for example, a categorized 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. RA7050 is steel grey similar to RAL7042. RA7050-GN is intended to be used in applications for plumbing and heating, such as in-house hot and cold water pipes and fittings, floor and wall heating systems and radiator connections. Former trade name for this product was Beta(ß)-PPR. Information provided by the Manufacturer.
