Polypropylene staple fiber has excellent comprehensive performance and a wide range of applications!

Jiangsu Haibang New Materials Co., Ltd., formerly known as Taizhou Hailun Chemical Fiber Co., Ltd., is a technical chemical fiber enterprise specializing in the research, development, production and sales of polypropylene staple fiber. The company has two factories in the north and south in Taizhou City, Jiangsu Province (18 kilometers apart), covering a total area of more than 100,000 square meters, including 50,000 square meters of factory buildings and over 10,000 square meters of office buildings. The company has 9 advanced fully automatic polypropylene staple fiber production lines with an annual designed production capacity of 90,000 tons. The company has established a complete polypropylene staple fiber testing laboratory, has a full set of fiber testing instruments, and has the ability to develop new polypropylene staple fiber products. The company produces a full range of polypropylene staple fiber products, with main applications including the automotive industry, sofa fabrics (cool cloth), geotextiles, liquid filtration, textiles, sanitary materials, carpets and other industries. The company has passed ISO9001:2015 international quality system certification.

Properties of Polypropylene staple fiber: Polypropylene is a highly crystalline (crystallinity up to 95%) thermoplastic resin with regular configuration. The product is a natural color granular material, a non-toxic, tasteless, odorless and lightweight polymer with a density of 0.90-0.91g/Cm3, which is one of the lighter general-purpose plastics. It has good rigidity and wear resistance, high hardness, and good high-temperature impact resistance (but it drops sharply below -5°C). It has strong resistance to repeated folding. It has good heat resistance, heat deformation temperature of 114°C, Vicat softening point>140°C, melting point of 164-167°C, continuous use temperature of 110-120°C, and under no-load conditions, the use temperature can reach 150°C. It is the only general-purpose plastic that can be boiled in water and sterilized at 130°C. It has good chemical stability and does not react with most chemicals except for strong oxidizing media. Its stability to water is particularly outstanding. It is not only insoluble in water, but also almost does not absorb water. The water absorption rate in water for 24 hours is only 0.01%. It has excellent electrical insulation performance, good voltage resistance and arc resistance. Its main disadvantages are poor light resistance, easy aging, poor cold resistance, poor low-temperature impact strength, poor toughness, high static electricity, poor dyeing, printing and adhesion, but it can be improved by adding additives, co-mixing and copolymerization.

Over the years, we have developed numerous varieties of Polypropylene staple fiber, including high-strength and high-modulus polypropylene for high-speed rail foundations, lightweight GMT hot-melt polypropylene, reinforced polypropylene for automobile structural parts, liquid filter adsorption polypropylene, wear-resistant high-strength polypropylene, low-odor and low-VOC polypropylene, which can Industry-leading fiber products such as dyed polypropylene and halogen-free flame-retardant polypropylene have replaced many imported needs. We have successfully used polypropylene staple fiber products to serve high-end industries such as high-speed railways, the Three Gorges Dam, various mid- to high-end automobiles, and direct drinking water. The product quality has reached a high level, saving a lot of investment for national projects. The company will continue to provide our customers with high-quality Polypropylene staple fiber products and excellent services, conduct in-depth research and development in the polypropylene staple fiber industry, and develop high-performance fiber products to serve the new material industry.
