PP is called polypropylene. It is a polymer made of propylene monomer through free radical polymerization. It has a non-toxic, odorless, tasteless, milky white and highly crystalline shape, and is a crystalline material.
PP spunbond non-woven fabric is a non-woven fabric made of polypropylene material.
It has the characteristics of high strength, small difference in vertical and horizontal strength; acid and alkali resistance, non-toxic, and harmless to human physiology; excellent breathability; liquid dyeing, non-fading and other characteristics! ?PP spunbond non-woven fabric has good heat resistance, with a melting point of 164~170℃, and the products can be sterilized at temperatures above 100℃.
It will not deform at 150℃ without being affected by external force.
The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and the heat resistance is not as good as PE.
?PP spunbond non-woven fabrics also have good chemical stability. In addition to being corroded by acids, they are relatively stable to various other chemical reagents. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc. can make non-woven fabrics Softening and swelling, chemical stability also improves with increasing crystallinity.
? It is an environmentally friendly new material manufacturer integrating R&D, production, customization and sales.
The company has always implemented the tenet of “quality first, reputation first”, with strong technical force, strict management system, brand-new production equipment, and complete testing instruments to ensure that everything puts the interests of users first and provides users with high-quality products.
