High Purity Calcium Metasilicate (Wollastonite) for Friction Materials

ULTRAFIBE products were designed for use in friction materials. The products vary in particle size and aspect ratio for desired performance and are available with chemical modifications for enhanced properties, processing and handling.

Key Features

• Improves or maintains frictional stability
• Improves physical and mechanical properties
• Improves fade and recovery
• Reduces moisture sensitivity
• Improves pre-form strength
• Reduction or elimination of surface cracking during braking
• Synergistic effect with other fibers
• High melting point – no decomposition of fiber at elevated temperatures
• No health related issues – environmentally safe

Recommended Applications

• Aerospace
• Heavy equipment and off-road industrial applications
• Heavy duty off road trucks
• OEM and aftermarket passenger cars and light trucks
• Semi-metallic and non-asbestos organic (NAO) formulations for truck blocks, drum linings, disc pads, clutch facings and shims
