PP-RCT is the abbreviation for Polypropylene Random Copolymer with modified crystalline structure and enhanced temperature performance. The PP-RCT material has a special fine and homogeneous crystal structure that improves the mechanical characteristics of the material.

PP-RCT pipe systems can be operated at higher stresses at elevated temperatures (>70°C). The material has an MRS value of 11.2 MPa, and more importantly, the CRS at 70°C and 50 years is 5 MPa compared to 3.2 MPa for standard PP-R.

The improved long-term strength of the PP-RCT material leads to a more eco- nomic dimensions of the pipe system. It enables designers to select thinner wall pipes or smaller diameter pipes.
