Peroxide Cross-linkable Insulation is made by low density polyethylene resin, adding such as peroxide crosslinking agent and other additives, through mixing, plasticizing and granulating.

Silane crosslinked insulating material is made by LDPE together with additives such as LLDPE, silane coupling agent initiator, anti-oxidant and etc,through mixing, plasticizing and granulation. (Two-step production technology, wherein A material is grafted material, B material is catalytic masterbatch.)
