Overview
PP yarn grade has excellent tensile properties and good processability. It is principally used in the production of plastics woven products. Products made from this resin are water repellent, resistant to corrosion, mildewing, abrasion and have long service lives.
Application
PP yarn grade is widely used in the production of woven bags, colored stripe cloth for sunlight shading or covering use, carpet backing (base fabric), container bags, tarpaulin and ropes. Products made from this resin are mainly used as packages for food, chemical fertilizer, cement, sugar, salt, industrial feedstock and ores.
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.
