MFP-TP

MFP-TP is a masterbatch prepared by filling 80% talc in PP (plastic).

Features of MFP-TP

1. If can increase the stiffness of the molded items.
2. It reduces shrinkage factor, because of which there would be lesser shrinkage and cavity, which would increase dimensional stability.
3. Because of higher heat distortion temperature, it improves heat resistance.
4. It improves properties such as increase in bending elasticity and bending strength, and shorter molding cycle.

Examples of Application of MFP-TP

1. Hangers
2. Automobile parts
3. In home appliance parts
4. Pellets, etc.

Property Values when Talc MB is added to PP

Test specimens are prepared with injection molding
Charpy impact test: Notch is cut after injection molding test preparation. Home PP is hammer 2J and block PP is hammer 7.5J.

Home PP : Prime polymer J108M
Block PP: Prime polymer J466HP
