PPRCT PIPE

PPRCT

PP-RCT is a polypropylene-random-copolymer which possesses a unique morphology. In comparison to standard PP-R, which displays only the monoclinic form (o(-form), the crystal structure of PP-RCT consists to a high degree of the hexagonal form (B-form) and to some minor extent of the monoclinic form. This b-nucleation" process enhances the crystalline structure which enables pipes produced from the material to operate at higher stresses at elevated temperatures. Pressure tests on pipes manufactured from PP-RCT materials demonstrates a 50 year strength at 70C of 5 MPa, compared to the 3.2 MPa for standard PP-R materials. Offering more than a 50% improvement in long-term strength, PP-RCT enables designers to select thinner walled pipes and in some situations also smaller diameter pipes can be used. This results in higher pipe hydraulic capacity or the possibility to apply higher pressure than with standard PP-R with PP-RCT (Polypropylene Random Crystallinity Temperature) is the newest generation and has better mechanical characteristics than PP-R. The improved mechanical characteristics come from the crystalline structure of the resin giving the material the ability to operate at higher stresses at elevated temperatures.
