Overview
LLDPE Rotomolding Grade is white, nontoxic, tasteless and odorless, supplied in pellets. It has excellent processability and high tensile strength, toughness and thermal stability. In addition, it has good environmental stress crack resistance(ESCR), impact resistance at low temperatures and low warpage.
Application
LLDPE Rotomolding Grade is mainly used for making rotomolded products, large-sized outdoor toys, storage tanks, roadblocks, etc.
Package, Storage & Transportation
The resin is packaged in internally film-coated polypropylenewoven 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.
