Grade
WCI PEX 1540
WCI PEX 1540 is a grafted polyethylene grade with maleic anhydride functionalization, designed for use in multilayer and hot-water pipe systems. It ensures excellent adhesion in PEX-AL-PEX structures, along with superior chemical and thermal resistance.
PEX is actually polyethylene whose molecular structure has been networked. This network formation makes the material:
Become more resistant to high heat
Retain flexibility
Be more resistant to cracking and pressure
