PP Granule Spunbond Nonwoven Fabric Pp Raw Material

Injection molding is one of the most important molding methods for PP Resin products. It is to add PP into the barrel of injection molding machine through the hopper, and after heating and melting to the flowing state, the plunger or screw pushes the melt forward to inject it into the closed mold with lower temperature, and then the melt filled with the mold cavity is fully cooled under pressure and keeps the shape given by the mold cavity, and finally the mold is released to take out the products. When processing large and thin products by injection molding, polypropylene with melt rate higher than 18g/10min can be used.

1.PP granule spunbond nonwoven fabric pp raw material Polypropylene is an odourless, tasteless, non-toxic and lightweight granule or powder with a relatively low density (0.89-0.91g/cm3).

2. PP granule spunbond nonwoven fabric pp raw material has a high melting temperature, good heat resistance, continuous use up to 120°C and can be sterilised at high temperatures. The melting point of homopolymer polypropylene is approximately 168°C and typical random copolymers have a melting point in the range of 145-151°C.

3. PP granule spunbond nonwoven fabric pp raw material has excellent mechanical properties such as yield strength, tensile strength, impact strength, surface hardness, rigidity and abrasion resistance, as well as good transparency and surface gloss.

4. PP granule spunbond nonwoven fabric pp raw material has good electrical insulation and a small dielectric constant.

5, PP granule spunbond nonwoven fabric pp raw material is not easy to absorb water, very easy to thermal oxidation and discolouration degradation, so polypropylene powder to add antioxidant system.

6, PP granule spunbond nonwoven fabric pp raw material has good resistance to stress cracking, in addition to strong oxidising agents and non-polar solvents, has a strong resistance to chemical erosion.
