Modern brake systems encounter diverse thermal cycling and load requirements across passenger and commercial vehicles, making targeted material selection essential for reliable NVH control. As a Leading manufacturer of NBR coated steel, we tailor our NBR coated roll, Rubber coating coil, and Brake shim material formulations to match different brake operating environments. Our engineered Rubber Materials deliver stable damping performance under city stop-start cycles, heavy-duty commercial braking, and can replace traditional multi-layer stacked shim designs to streamline assembly and inventory management for brake manufacturers.

NBR Coated Shim for Frequent City Stop-Start Conditions: Resist Repeated Thermal Shock

For passenger vehicles operating in urban traffic, brakes undergo continuous heating and cooling cycles with frequent stopstart events. Conventional brake shim materials tend to lose elasticity after repeated thermal shock, leading to gradual degradation of noise damping performance and rising brake squeal complaints.

Our NBR coated roll and Rubber coating coil formulated for passenger car brake shims maintain stable elastomer elasticity under recurring temperature fluctuations. Even with continuous thermal cycling during city driving, the NBR layer retains its damping properties. This ensures the Brake shim material consistently suppresses brake vibration and squeal, with no noticeable decay in NVH performance over time. The specially tuned Rubber Materials are optimized for the moderate load, rapid thermal swing profile typical of passenger vehicle urban operation.

NBR Coated Damping Material Selection for Heavy-Duty Commercial Vehicle Braking

Heavy-duty trucks and buses generate far higher clamping loads, greater braking torque and sustained thermal stress compared to passenger cars. In these harsh working conditions, brake shim materials demand superior compression resistance and fatigue endurance.

We maintain distinct formulation grades for passenger and commercial vehicle applications. Our commercial-grade Brake shim material built on NBR coated roll and Rubber coating coil features enhanced cross-link density of the Rubber Materials. The upgraded NBR coating delivers higher compression resistance and anti-fatigue capability, resisting permanent compression set under heavy cyclic load. This prevents the damping layer from flattening or losing vibration absorption capacity under repeated heavy braking. Our engineering team helps customers select the correct grade of NBR coated steel according to axle load, braking duty cycle and peak temperature of commercial brake systems.

Backing Plate Damping for Disc Brakes: NBR Coated Steel as an Alternative to Multi-Layer Composite Shim Stacks

Many brake manufacturers still rely on multi-layer stacked composite shims for disc brake backing plate NVH control. Multiple stacked components increase part variety, complicate inventory planning and slow down manual or automated assembly processes.

Our Rubber coating coil and NBR coated roll serve as a simplified single-substitute solution for traditional multi-layer composite shim stacks. By using integrated Brake shim material made of NBR coated steel, customers can reduce their bill of materials and eliminate cumbersome multi-part stacking operations. This consolidation simplifies part number management, cuts inventory SKUs and reduces assembly errors on brake pad production lines. As a Leading manufacturer of NBR coated steel, we provide this consolidated Rubber Materials solution without sacrificing NVH damping performance for disc brake backing plate applications.

Application Summary

Different vehicle operating scenarios require differentiated Rubber Materials design for brake shims. Our portfolio of NBR coated roll and Rubber coating coil covers passenger vehicle city stop-start thermal shock, heavy-duty commercial high-load braking, and disc brake backing plate damping. Our Brake shim material can replace multi-layer stacked shim structures to simplify procurement and assembly. As a Leading manufacturer of NBR coated steel, we support brake OEMs and friction material producers with grade-specific material recommendations and batch-stable rubber coated steel for global brake NVH projects.
