A unique rubber-to-metal composite material designed to solve noise and vibration problems.

Trelleborg Damping Solutions Kalmar manufactures a wide range of noise damping shims / insulators that are used when endurance against thermal, chemical and mechanical stress is required. This is combined with outstanding sound damping, sealing, vibration insulation, compressibility and bonding capacity.

The materials consist of different combinations of layers of rubber, carbon steel, stainless steel, fibre glass, cold pressure adhesives, acrylic or silicone based and hot sensitive glues.

Our unique rubber-to-metal composite materials for noise damping in disc brakes combine a number of valuable properties: vibration insulation, compressibility and excellent adhesion. The rubber composite materials are excellent for applications with demanding insulation for vibration and noise. The materials retain their integrity even when subjected to high pressure and high temperature.

Noise damping components in brakes have to endure enormous strains and tension - extreme temperature, mechanical stress, salt, water, oil etc… Testing one and the same brake system in mountain and desert country, as well as in urban traffic and on the open highway is a costly and time consuming process.

We simplify this process by running tests in our fully computerized brake-noise dynamometers, equipped with unique acclimatiser. This allows us to literally test a brake in any climate in the world.

Outstanding Performance
