Special mineral fibers for brake pads: enhancing braking safety and quietness HB212
Core Product Value: Why Brake Pad Manufacturers Choose HB212?
Precise Mechanical Support: Optimized length of 280±100 microns allows for the formation of a three-dimensional network structure within the friction material, significantly improving the brake pad's shear strength, compressive strength, and overall structural stability, reducing the risk of uneven wear and cracking at high temperatures.
Excellent Thermal Management Assistant: The fibers themselves withstand temperatures exceeding 1000°C and effectively absorb and conduct instantaneous high heat generated during braking, helping to dissipate frictional heat from the contact interface more quickly, slowing down heat fade, and maintaining braking force stability.
Achieving Silent Braking: Its unique fiber morphology and surface properties effectively dampen high-frequency vibrations generated during braking, making it a key functional material for solving brake noise (screeching) problems.
Safety and Environmental Guarantee: 100% asbestos-free, fully compliant with global automotive supply chain environmental and safety regulations (such as RoHS, EU REACH SVHC, etc.), ensuring your products can enter domestic and international markets without worry.
Improved wear resistance and lifespan: The high hardness of the fiber and its strong bond with the matrix can effectively reduce abnormal wear of friction materials and extend the service life of brake pads, making it especially suitable for commercial vehicles with stringent durability requirements.

Advantages of HB212 Fiber in Brake Pad Formulations
HB212 fiber can be seamlessly integrated into various brake pad formulations, including semi-metallic, low-metallic, ceramic, and NAO (asbestos-free organic) formulations:
Strengthened Structure: As a "skeleton material," it withstands frictional stress and prevents premature material peeling.
Adjusted Coefficient of Friction: It helps stabilize the coefficient of friction, resulting in more consistent performance across different temperature ranges.
Improved Processability: Its excellent dispersibility leads to more uniform premixes and better molding properties.
Optimized Cost-Performance Ratio: While improving performance, it is an effective alternative to some expensive materials.
