The stable random copolymerized polypropylene pipe(stable PP-R pipe for short)is a kind of latest environment-friendly composite tube,which is made up of a metal tube and a series of protective layers fixed together by specialized hot colloidal PERFORMANCE ATTRIBUTES

1.The coefficient of thermal expansion of it is 1/3 that of the common PP-R tube,and it will not be distorted by the long period of exposure to hot water.

2.The Aluminum and the plastic are fixed tightly,which renders it uviofast and ensures a longer longetivity.

3.It adopts the homogeneous connection by hot colloidal sols and is conveniently fixed,reliable and time saving.

4.It is hygienic and innocuous.It meets the standard of GB/T17219-1998 and is qualified for a type of environment-friendly product.
