Polypropylene is a kind of polymer commonly used in the spinning process. The main performance parameters are isotacticity, melt index (MFI) and ash content.



The spin-forming process requires that the isotacticity of polypropylene should be above 95%. If it is less than 90%, spinning will be difficult.



During the polymerization process, three configurations of polymers can be produced due to the different positions of methyl groups in the steric space.



Features: high strength, good high temperature resistance, aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, moth-proof, non-toxic.



Process flow: polymer (polypropylene + return material) - large screw high temperature melt extrusion - filter - metering pump (quantitative conveying) - spinning (up and down stretching and suction at the entrance) - Cooling - Air Traction - Web Curtain Forming - Upper and Lower Rollers (Pre-Reinforcement) - Mill Hot Rolling (Reinforcement) - Winding - Inverted Slitting - Weighing Packaging - Finished Product Storage p>
