Description
SLX-23 (Silox 23 from Momentive)is a liquid additive that is an excellent candidate to consider for crosslinking high- and medium-density polyethylene (PEXb) for use in potable water pipes. This product is a vinyl silane and peroxide combination that can provide high grafting efficiency in a Sioplas process. In the second process step it can be used in combination with an antioxidant and catalyst masterbatch. It is available as a solid, free flowing pellet. This masterbatch helps to provide chlorine resistance to the finished pipe in drinking water applications.
