Binder (Phenolic Resin / ModifiedResin) Bonds all fillers, determines heat resistanceand bonding strength Superstop: Modified resin with heat resistance >350°Cno delamination or debonding.Inferior: Ordinary resin carbonizes at 200°C, causingfriction layer peeling.
Reinforcing Fiber (Steel Fiber / CopperFiber / Ceramic Fiber)Enhances structural strength and impactresistance, determines wear resistance.Enhances structural strength and impactresistance, determines wear resistance.
Filler / Regulator (Graphite / AntimonySulfide / Zirconium Silicate)Adjusts friction coefficient, reduces noise,improves heat dissipation.Superstop: Precise formula ratio, stable at FF/GGgradeInferior: Excessive barite usage, high u at roomtemperature but severe high-temperature heat fade.
Cold-Rolled Steel Sheet (Q235B/SPCC)Bears pressure, transmits braking force, andserves as the safety base.Superstop: Original sheet thickness >4.5mm,galvanized/electrophoretic anti-corrosion, excellentrust resistance.Inferior: Uses recycled steel, insufficient thickness,orone to deformation and fracture.
Noise Reduction Shim / Damping Pad(Rubber/Metal Composite)Absorbs vibration, eliminates high-frequencysqueal (solves NVH pain points)Superstop: Precise die-cutting, tight bonding, hightemperature resistance without peeling.Inferior: Ordinary rubber, ages and peels off at hightemperature, causing severe noise.
