Overview
LDPE wire & cable grade has a density and melt flow rate very suitable for the material being used as cable base material. This is achieved by controlling its molecular structure. The resin has high dielectric strength and volume resistivity, low dielectric loss tangent and dielectric constant.
Applications
LDPE wire & cable grade is mainly used for producing the base materials for high-voltage chemical crosslinking polyethylene insulating material and low and medium-voltage silane crosslinking polyethylene insulating material.
Package, Storage & Transportation
The resin is packaged in polypropylene woven bags. The net weight is 25Kg/bag. The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flammable substance is strictly prohibited.
