Polypropylene Random Copolymer:

ALMATHERM pipes and fittings are produced from Polypropylene Random Copolymer Type 3 as raw material having low melt flow rate, high molecular weight and good flexibility.

This raw material is recommended for the production of pressure pipes including potable water transfer lines, hot and cold water transfer lines, floor heating and also for chemical industry applications. Good long term pressure resistance and easy processing and installation technique give cold and hot water systems made of PP-R pipes an advantage as alternative to the traditional systems.

Polypropylene Copolymer type 3 corresponds to German DIN standards:

a- DIN 8077 Dec. 1997 PP Pipe Dimensions

b- DIN 8078 April 1996 PP Pipes General Quality Requirements and Testing.
