Sinopec PP L5D89 is a raffia-grade polypropylene homopolymer resin engineered for high-performance raffia and industrial woven applications. Produced using advanced gas-phase polymerization technology, the resin offers an excellent balance of tensile strength, stiffness, melt flow consistency, and processing reliability.

The material is widely used in woven bags, jumbo bags, ropes, monofilaments, tarpaulins, carpet backing fabrics, and other industrial packaging products. Its superior orientation capability and stable extrusion performance make Sinopec L5D89 especially suitable for high-speed raffia tape production and weaving operations.
