DETAILS
 

ACTIVE ACICULAR WOLLASTONITE 


Features:

we treat wollastonite powder by coupling agent.

It has features of hydrophobic property. When put it on the water, it can float.


Application:

(1) Application in building materials: widely used in EPS insulation mortar, polystyrene board adhesive, fire retardant coatings, relief coatings, calcium silicate board, and dry powder mortar.

(2) Application in friction material aspect: widely used in friction material instead of asbestos non asbestos friction materials, improve product effect, sensitivity, smoothness, reduce noise, cracking and calcification.

(3) Application in the glass steel products: advise to use 600 mesh

(4) Used in the application of engineering plastics: advise using active fine needle 800 mesh

(5) Used in rubber products: by superfine wollastonite short fiber special surface activation treatment, instead of part of silica in rubber products, improve product strength, hardness, wear resistance and anti aging, replace 1/4 silica.
