Perforated Aluminum Foil for Pipes Specifications
1.Coating material:Polypropylene,QF551
2.Application:PPR pipes
3.EN575/EN546
SPECIFICATIONS
KING PLASTIC Stabi PP-R pipes are made of random copolymer polypropylene (PP-R) inside of which an aluminium layer has been placed. As a result, thermal expansion was reduced and the product’s resistance – enhanced.
This type of pipe has a structure of five layers: the inner and outer layers are made of PP-R, which are tightly bonded with PP-based adhesive to the mid-layer of aluminum, which is weII joined through welding.
Greatly reduced linear expansion coefficient, only 1/4 of that of plain PPR pipes
Improved resistant to impulse under low temperature, resistant to UV-ray
Can work under higher temperature and higher pressure
