Applications
1. PE building waterproof film, due to the requirements of tear resistance, the original formula without calcium carbonate added, the use of calcium carbonate masterbatch, the three composite membrane structure, the middle layer can be added 60% calcium carbonate masterbatch , The other two layers can be added 30% calcium carbonate masterbatch, all aspects of the test can be passed.
2. MPP electric tube, the original formula to add calcium carbonate masterbatch 5-8%, now add 20%, because the proportion of larger, the new formula to make the wall thin, all aspects of the test can be passed.
3. The proportion of alternative talc powder specific application is the car trunk spare tire cover, PP honeycomb board.
