Understand the nature of polypropylene staple fiber!

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

Polypropylene staple fiber 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.
