Product Description

Calcium carbonate whisker is another new type of inorganic filling after nano-calcium carbonate, non-toxic, odorless, white pine solid (needle single crystal under the microscope) as a new generation of filling materials, the product has the following properties and characteristics:
Comprehensive performance of high mechanical strength, and in the use of the process can reduce vibration, anti-slip, noise reduction, wave absorption; Good overall performance, high friction coefficient, high wear resistance and heat resistance; The friction performance is stable, and the thermal decay and thermal recovery performance is good. Especially, the filling of calcium carbonate whisker organically unizes the friction and wear reduction in one system, and the high temperature friction and wear performance is superior. It can reduce the amount of high value materials such as aromatic fiber, steel fiber, copper, potassium titanate and so on, and greatly reduce the cost of friction materials; The powder produced after friction is non-toxic and has little pollution.
