New technology makes PEX pipe in one step

Davis-Standard and OSi, two business units of Crompton Corp., have joined technologies to facilitate the production of cross-linkable polyethylene for pipe. Davis-Standard’s extrusion technology combined with OSi’s III dry silane product, XL-PEarl, will enable processors to economically produce PEX pipe products using a one-step process.

Until now, the silane process required two steps: grafting the silane and then manufacturing the product. Using XL-PEarl, it is possible to add the silane at the extruder throat, eliminating the grafting step.

Cross-linked pipe is a rapidly growing product in a market dominated by copper pipe. Cross-linking raises the thermal stability of PE, making it suitable for applications such as hot-water transmission and radiant heating.
