Mineral Modified PP Granules(T10-T40)

PP is the base resin and it is evenly mixed with mineral powder and processing modifier in a high speed, mineral modified PP granules come into being after twin-screw kneading granulation. This product possesses excellent mechanical strength, excellent resistance to stress cracking, heat resistance and good workability. This mineral filled polypropylene is widely used for electroplating processing and injection molding. It is also applied in home appliances, automotive interior trim, electronic appliances and other fields.

Characteristics of Mineral Modified PP Granules (T10-T40)
1. This mineral filled polypropylene has good mineral modified property and excellent surface gloss.
2. It enjoys the advantages of high rigidity and good dimensional stability.
3. We can provide PP granules with different colors according to clients’ needs.
