Polypropylene granule for natural color, cylindrical, smooth. particle size in any direction of 2mm ~ 5mm, tasteless, no mechanical impurities.

High purity propylene as the main raw material, ethylene as the copolymer, Polypropylene powder was prepared by gas reaction at 62℃ ~ 80℃ and pressure below 4.0MPa with highly active catalyst. After drying, mixing, extrusion, granulation, screening, homogenization into polypropylene particles. Density of 0.90 g/cm3 ~ 0.91g/cm3, is a lighter plastic in general use.

Characteristics

1. Pure PP raw materials, not filled with any chemical agent and modifier raw materials, only the general characteristics of PP materials.

2. Fill the general chemical raw materials, enhance the chemical resistance, temperature resistance, impact resistance, weather resistance of PP.

3. Glass fiber reinforced PP, PP raw material molding products after the shrinkage is relatively large, stiffness is general, so after glass fiber filling enhanced material shrinkage, so as to make up for the defects of PP raw material in various high-precision parts application.

4. mineral filling PP, mineral filling PP raw materials mainly change the impact resistance of raw materials, paint, chemical resistance, and shrinkage. The filling material is mainly calcium carbonate and talcum powder.

5. The remaining modified materials are seldom used to change the resistivity of materials to achieve antistatic and conductive properties.
