Product Description
Description: GreenThinking® WL with surface treatment and activation is refined from selected natural siliconemine of long needle wollastonite by Poweflex companyApplications:
GreenThinking® WL is wildly used in industries of rubber, functional plastic, coating andfriction materials.
The strict internal quality control process makes GreenThinking® WL have uniformchemical purity and stability of the particle size distribution. Good chemical activity ofGreenThinking® WL make it became functional filler in many products.
Key benefits:
Stable chemical composition, high whiteness
WL series cover all kinds of high quality long needle wollastonite products, unique mineralsource, high aspect ratio.
PH value close to neutral and advanced production technology of special silane treatmentmakes high coating rate.
Good tensile strength, good elongation at break, low compression set, good oil resistance,high rebound and other good mechanical properties and good wear resistance in rubberand plastic industry.
It improves corrosion resistance, chemical inertia, heat resistance, mechanical properties,and reduces cracking and use in industrial coatings,
