Overview
PP foaming grade is optimised to deliver good heat resistance, improved processability, broad process temperature range, foamability in foaming extrusion/injection/beads processes, good dimensional stability, wide range of foaming rate, good oil and chemical product resistance,non-poisonous, environmentally friendly, recyclable, energy and resource saving.
Application
PP foaming grade is mainly used to produce packing materials, thermal insulation material, automobile components, building materials and sports equipment by foam extrusion/injection, thermalforming and sheet/board extrusion.
Package, Storage & Transportation
The resin is packaged in internally film-coated polypropylene woven bags or FFS film 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.
