Example 2: Calcium Sulphate Whisker applications in the production of friction materials

Formula: Calcium sulphate whisker is a substitute of asbestos.

Effect:Because of CSW is Innocuous and substitutes of Asbestos, by adding this materials friction materials have not only friction coefficient even between 100 ~ 200°C, low wear and rear rate, and green environmental protection. Particularly it is suitable for the production of car friction disk.





Featurs:



Reinforcing engineering plastics and rubber products. Toughed goods are widely in applicants in spare parts for electronics, electric appliance.
Friction and sealed materials. It can be replacement of asbestos, produce free-asbestos brake and sealed products. Also it can use in dual parts opposite brakes.
Improve asphaltum intenerating temprature, produce Flame-retardent paper and heat-endure conveyer belt.
For light weight thermal insulating materials, paint, adhesive, oil paint.
For Dental, to improve dental material toughness, surface finish and wear resistance and decrease shrinkage rate.
For glass, steel products, if 15-20% CSW mixed into resins, it cooperate with glass fabric. So it can improve products of interlaminar shear strength and surface finish.
