Reshaping the Balance of Material Strength and Quiet Operation with Precision Fiber HB212
Why Choose HB212?
"Golden Length" Fiber: The precise control of 280±100 micrometers allows it to penetrate deep into the matrix to form a three-dimensional network reinforcement, while also facilitating uniform dispersion during mixing, preventing clumping and improving product uniformity.
A Silent Guardian: Excellent fiber morphology and surface properties effectively dampen and absorb mechanical vibration and noise, making it particularly suitable for friction materials requiring quiet braking.
High-Temperature Loyalty: Withstands temperatures above 1000°C, ensuring stable fiber structure under extreme friction conditions, preventing decomposition and deterioration, and maintaining material integrity for a long time.
A Safe Choice: Eliminates asbestos at the source and passes stringent EU RoHS and Substances of Very High Concern (SVHC) testing, providing your products with a global market passport.
