PP staple fiber is a type of polypropylene staple fiber, specifications 1.5-20dt, length 38-100mm. Hai'an County Qinfeng Chemical Fiber Co., Ltd. has a short-term price advantage for PP staple fiber.

PP staple fiber use:

1, PP staple fiber for baby care products, baby diapers, baby diapers.

2. PP short fibers are used for women's care products, women's sanitary napkins, and sanitary pads.

3, PP staple fiber for adult care products, adult diapers, adult diapers.

4, PP short fiber for home care products, pet cleaning pads, wipe cloth.

5, PP short fiber used for medical and health supplies, masks.

PP staple fiber has so many uses. Hai'an County Qinfeng Chemical Fiber Co., Ltd. has a mature production process, and has a perfect and strict inspection process, and its product quality tends to be international.

PP is a non-polar crystalline polymer, excellent electrical properties, can be made of high-frequency electrical insulation material, electrical insulation properties are also good in a humid environment. PP permeability, low permeability, high shrinkage, unmodified PP is not suitable for engineering components.

PP's resistance to fatigue and bending is good, can be bent 100,000 times, stronger than ordinary plastic, can be used as a living hinge.

PP plastic products are very sensitive to the gap effect, so when designing products, it should avoid sharp angles, gaps, and avoid large disparities. The tensile strength of PP is generally 21~39MPa, bending strength is 42~56MPa, compressive strength is 39~56MPa, breaking elongation is 200%~400%, notched impact strength is 2.2~5KJ/m2, low temperature notched impact strength 1~2KJ/m2, Rockwell hardness R95~105.

PP is less rigid and less wear resistant than PVC. PP has poor weathering resistance and must be supplemented with antioxidants or UV absorbers. Copper can also accelerate PP aging.

The use of fillers and reinforcing agents in PP makes it possible to utilize PP's high chemical resistance and stress crack resistance at high temperatures and to have high stiffness at room temperature. The brittleness of PP increases when the temperature is below 0°C, but it is further exacerbated by the use of fillers. In this case, the copolymer with ethylene has a high impact strength.
