Applications:

• WL920 is produced through a strict internal quality control process, so that the products have uniform chemical purity, stable particle size distribution and good chemical activity, and become a widely used multi-functional filler.
• The products enjoy a good reputation in rubber, functional plastics, coatings, friction materials and other industries.

 

Key Benefits:

• Stable chemical composition and high whiteness;
• Covering various high-quality long-needle wollastonite products with unique mineral source and high length-diameter ratio;
• The PH value is close to neutral, the special silane treatment is carried out under the advanced production process, and the coating rate is high;
• In the rubber and plastic industry, it has good mechanical properties and wear resistance, such as strength, elongation, low pressure change, oil resistance, high resilience, etc.
• In industrial coatings, it improves corrosion resistance, chemical inertness, heat resistance, mechanical properties, reduced cracking and durability of use.
