PP-RCT (PolyPropylene-Random Crystallinity Temperature) is a material classification defined in ISO 1043-1:2001 to describe the second-generation class of PP-R materials. This pipe class, PP-RCT, has recently been included in EN ISO 15874, the global standard for plastics piping systems for Hot and Cold Water pipe installations and enable increased performance and competitiveness for pipe producers.

RA7050-GN is a PP-RCT polypropylene-random-copolymer with a special crystallinity brought about by a special beta-nucleation which exhibits an improved pressure resistance, especially at elevated temperatures. PP-RCT materials such as RA7050-GN are designed to fulfil the PP-RCT pipe class as described in the EN ISO 15874 standard, e.g. 50 years service life at 70°C at 5 MPa, compared to 3.2 MPa for standard PP-R materials when tested according to the ISO 9080 pipe pressure tests.

RA7050-GN is ready compounded for maximum quality control. The colour of RA7050-GN is green similar to RAL 6024.

Applications
In general 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.
