Polylink Polymer PP 408-401-P-10040-B

About
This compound utilizes the system for cross linking of polyethylene developed by DOW Corning and known as Sioplas. It is a three component system comprising a silylated ethylene polymer known as the graft copolymer PP 408, a tin based cross-linking catalyst master batch PP 401 and also a master batch P-10040-B containing lubricant, UV ingredient and suitable grade of carbon black. These three material are normally used in the ratio of 90 parts graft, 5 parts catalyst master batch and 5 parts special black masterbatches. Stored separately, these materials are fairly stable but when mixed and exposed to moisture, crosslinking takes place. This system allows the compound to be extruded as a normal thermoplastic which will then attain a high level of cross linking in the processed from. The finished product has all the properties associatedwith polyethylene cross linked by other methods. Silane grafted black cross linkable polythylene for over head cables.&&
