This is currently the most widely used resin in spunbond fabrics. It is generally rheology-controlled, with high uniformity and high quality. Main indicators: Melt index ≥ 27, molecular weight distribution 180000~300000, ash content ~200mg/kg, isotacticity ≥ 95. Because PP has the advantages of high strength, low melting point, good processing performance, good chemical resistance, low density and low price, it is widely used in the fields of women's sanitary napkins, baby diapers, adult diapers, agricultural harvest cloth and furniture packaging materials. application.
