Product Overview
HB-GL02 reinforced mineral fiber, hailed as "angel's hair," is made from high-quality basalt, diabase, and dolomite as main raw materials. It is produced through high-temperature melting and high-speed centrifugal spinning to create inorganic silicate fibers, which are then refined through multiple processes including length setting, slag removal, and surface treatment. This product boasts superior characteristics such as safety and environmental friendliness, high temperature resistance, structural reinforcement, noise reduction, and durability, and is widely used in high-performance friction materials.

Product Features
Safe and Environmentally Friendly · Asbestos-Free Design
The product eliminates asbestos hazards at the source, complying with the strictest global environmental and occupational health and safety regulations, providing users with dual health protection.

High Temperature Resistance · Stable Performance
The unique high-alumina, high-silicon, and high-iron formula gives the fiber extremely high thermal stability. Even under extreme friction temperatures above 800℃, the fiber structure remains intact, effectively preventing brake pad thermal fade.

Structural Reinforcement & Crack and Shatter Resistance: Even after high-temperature ablation, the fibers retain their intact shape and strength, forming a stable three-dimensional network structure within the friction material. Like "micro-reinforcing bars," this significantly enhances the brake pad's shear and impact resistance, preventing chipping and cracking.

Noise Reduction & Enhanced Comfort: The extremely low slag content ensures the uniformity and density of the friction material, effectively absorbing vibration and reducing high-frequency noise and vibration during braking, resulting in a smooth and quiet driving experience.

Durable & Stable Performance: High-quality mineral fibers are firmly bonded to the matrix material, evenly bearing and transmitting frictional forces, reducing abnormal wear, helping to extend brake pad life, and maintaining stable and reliable braking performance.
