Spun bond non woven machine raw material

Raw material of PP Spunbond Non Woven Machine

PP polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0.90~0.91g/cm3, which is currently one of the lightest varieties of all plastics. It is particularly stable to water, the water absorption rate in water for 24 hours is only 0.01%, and the molecular weight is between 80,000 and 150,000. The moldability is good, but because of the large shrinkage, thick-walled products are easy to dent. The surface of the product has good gloss and is easy to color.

Good use in the PP Spunbond Non Woven Fabric making line.

PP filling modification, adding a certain amount of inorganic minerals to PP, such as talc, calcium carbonate, titanium dioxide, mica, etc., can increase rigidity, improve heat resistance and gloss; add carbon fiber, boron fiber, glass fiber, etc. Improve tensile strength; adding flame retardant can improve flame retardant performance; adding antistatic agent, coloring agent, dispersant, etc. can respectively improve antistatic property, coloring and fluidity, etc.; adding nucleating agent can speed up The crystallization speed increases the crystallization temperature to form more and smaller spherical crystals, thereby improving transparency and impact strength.

Seek Winwin Machinery company offer spunbond Non Woven Fabric Machine, high speed can be 800m/min.
