KLJ Group KLJ-XL-11 XLPE
Categories: Polymer; Thermoplastic; Polyethylene (PE)

Material Notes: KLJ-XL compounds are a combination of LLDPE base material and catalyst master batch. The base polymer LLDPE is grafted with Vinyl Silane. The process results in moisture/ambient curable polymer having excellent processing characteristics without any volatiles. When properly mixed, addition of 5 parts of corresponding catalyst materbatch to 95 parts of grafted polymer, an insulation with excellent thermo-oxidative stability is achieved.

Application: Grafted polymer & corresponding catalyst masterbatch of each grade is designed for insulation of low voltage (up to 6 KVA)/medium voltage (up to 33 KVA) application and power cables.

Specifications: Grafted polymer in combination with corresponding catalyst masterbatch meets the following specifications, when processed using sound extrusion practice and testing procedures.

IEC-60502, IS-7098 (Part-I & II), IS 3396
