Example 6: Calcium Sulphate Whisker applications in the friction material

Formula (percentage by weight):Generally dosage of calcium sulphate whisker in the friction material is 8 ~ 15%, up to a maximum of 20%.

Effect:After adding calcium sulphate whisker in the friction material, the shear strength of the material and the impact strength improve obviously, friction coefficient under high temperature environment and well wear resistance, and environmental protection (instead of asbestos, whisker is non-toxic itself, brake dust less, low noise, lower cost etc. ).



Features:

1, CaSO4 Whisker is eco-friendly selected from food-grade gypsum.

2, Soften the friction material.


3. Stabilizing friction coefficient.


4. High wear resistance and heat resistance.



5. Reducing shock,lower noise,absorbing micro-wave.



6. Without poisonous ash when braking.



7. Extending the life circle.



8. Reducing the dosage of resins and expensive whisker to improve the competitiveness of final products.
