APPEX 14 and APPEX 15 are two-step, silane-grafted, moisture cross- linkable high density polyethylene system (XLPE). These products allows for a distinct advantage over regular polyethylene: greatly improved heat resistance. Made by following the Sioplas two-step technology, APPEX offers the processor significant advantages and economies over organic peroxide, radiation and reactor copolymer cross-linking processes. PEX pipes manufactured by APPEX have features include: -Excellent heat resistance to 90°C
-Excellent environmental stress crack resistance (ESCR)
-High resistance to scratch, abrasion and chemical functions -Good resistance to rapid propagation of tension
-Excellent creep resistance to 95°C
