Polypropylene flame retardant yarn improves safety index!

Polypropylene flame retardant yarn is a phosphorus-containing flame-retardant fiber prepared by co-polycondensation by adding phosphorus-based environmental protection flame retardant in the polymerization process. Since the flame retardant components are evenly attached to the macromolecules, it gives the fabric permanent flame retardant properties.

Polypropylene flame retardant yarn has high safety and reliability, does not contain halogen elements, only contains C, H, O and a small amount of phosphorus elements. Compared with traditional halogen flame retardants, it will not produce suffocating toxic gases when burning . The flame retardant limit oxygen index (LOI) of polypropylene flame retardant yarn is above 35%, and the flame retardant effect is better.

The flame-retardant fabric made of Polypropylene flame retardant yarn can reduce the flammability of the fabric during the flame combustion, slow down the speed of spread, and not form a large area of combustion. flame retardant purpose.

Changzhou Shengjie Heli Chemical Fiber Co., Ltd. was founded in 1999 and is located in Zhendong Industrial Zone, Huangli Town, Wujin District, Changzhou City. Enterprises of polypropylene flame retardant yarn, polyester FDY yarn and air-transformed yarn.
