The use of polypropylene staple fiber: polypropylene has excellent comprehensive performance and wide application range.

Polypropylene is a highly crystalline (95% crystallinity) thermoplastic resin with a regular configuration. The product is a natural grain, non-toxic, tasteless, odorless and lightweight polymer, with a density of 0.90 ~ 0.91g/Cm3, which is the lightest of general plastics. Rigidity, good wear resistance, high hardness, high temperature impact (but below -5℃ is sharply reduced). Strong resistance to repeated folding. Good heat resistance, thermal deformation temperature 114 ° C, Veka softening point >140 ° C, melting point 164 ~ 167 ° C, continuous use temperature up to 110 ~ 120 ° C, in the case of no load, the use temperature up to 150 ° C, is the only general plastic can be boiled in water, and can be disinfected at 130 ° C products. Good chemical stability, in addition to the strong oxidizing medium, and most chemicals do not act. The stability of water is particularly outstanding, not only insoluble in water, but also almost non-absorbent, and the water absorption rate of 24h in water is only 0.01%. Excellent electrical insulation, good voltage and arc resistance. Its main disadvantages are poor light resistance and easy aging; Cold resistance is poor, low temperature impact strength is poor, toughness is not good, electrostatic degree is high, dyeing, printability and adhesion is poor, but it can be improved by adding additives and co-mixing copolymerization.

Hubei Botao Synthetic Fiber Co., Ltd. was established in October 2000, specializing in the production and sales of polypropylene, polyester, composite fiber, polylactic acid staple fiber, the products are mainly used in non-woven fabrics, automotive interior, geotextiles, carpets, filtration and other industries. The company is located in Jingmen City, Hubei Province, now has six branches, covering a total area of 300,000 square meters. The company is equipped with imported fiber production line, fixed assets of more than 100 million yuan, an annual output of 50,000 tons of polypropylene staple fiber, 20,000 tons of polyester staple fiber, 10,000 tons of composite fiber, the annual output value of more than 500 million yuan.

The company insists on technological innovation as the basis, the introduction of new technical talents, cooperation with universities and colleges and universities research and development, to create high-end Botao brand, keep up with the market demand research and development of automotive interior, high-speed rail geotextile polypropylene staple fiber to fill the market gap. The company has more than 280 employees, including 8 engineers, more than 30 other technical personnel, strong technical force, with strict quality testing system and independent research and development, production and marketing capabilities, is a leading enterprise in China's polypropylene industry, participated in the drafting of the "polypropylene staple fiber" industry standard, is the China Chemical Fiber Association polypropylene branch vice president unit.
