PP is polypropylene. The imported spunbond non-woven fabric made of this material is one of the more high-end varieties of bag filter materials. Let’s learn more about it.
Melt-blown cloth uses polypropylene as the main raw material, and the fiber diameter is 1 to 5 microns.
Ultrafine fibers with many voids, fluffy structure and good anti-wrinkle ability. The unique capillary structure can increase the number and surface area of fibers per unit area, thus making the melt-blown cloth have good filtering, shielding and thermal insulation properties. and oil absorbency.
Can be used in fields such as air and liquid filter materials, isolation materials, absorbent materials, mask materials, thermal insulation materials, oil-absorbent materials and wipers.
Imported spunbond non-woven fabric is a non-toxic, odorless, milky white, highly crystalline polymer. It is one of the lightest varieties of all plastics at present. It is particularly stable to water, with a water absorption rate of only 0.01% in 14 hours in water.
The molecular weight is about 80,000 to 150,000, and the formability is good.
It 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.
