KLINGER Polystrat Brake Shim Sheets

For automotive disc pad brake applications. KLINGER Polystrat brake shim sheets have a steel base coated with a rubber layer on each side, creating a noise damping material for disc pad brakes.

KLINGER Polystrat are steel base, generally coated with a rubber layer on each side creating a noise damping material for disc pad brakes applications.

Polystrat BT38-21 and Polystrat BT38-20. Both are noise absorbing shims for brake disks that feature a rubber coating on both sides, which is subsequently vulcanized. Polystrat BT38-21, however, is also characterized by an additional acrylic adhesive, which is applied to the inner face of the rubber. It serves to further increase the sealing strength. Due to its higher quality, Polystrat BT38-21 is typically used by original equipment manufacturers, while BT38-20 is very popular in the after-market segment.

Polystrat is proven as the leading rubber coated steel choice in millions of vehicles. In the anti-noise Shim application for Passenger brake pads, the shim serves to reduce the noise, vibrations and harshness (NVH) resulting from the braking process.
