Rubber coated metal coil sheet
Rubber coated metal sheet (RCM sheet) is made from metal substrate coated with thin NBR rubber or other rubber layers through advanced processing technology.
A continuous length RCM coil sheet is made from an entire coil of metal sheet through a series of treatments and rubber coating process automatically and continuously in our special production line.

Properties & Applications:
The RCM sheet has good sealing performance, good anti-squeal performance, excellent chemical resistance and anti-aging properties, and good machinability.
It is widely used as gasket material for engines, compressors, refrigerating machines, and as anti-squeal shim material for braking system.
RCM Sheets for Sealing Gaskets
RCM sheet has excellent heat resistance, oil resistance and antifreeze resistance property. It can ensure good sealing performance even under harsh working environment in the engine. Therefore, RCM sheet is often selected as oil or water sealing gasket material for engines.
Our various styles of double-sided and single-sided rubber coated metal sheets can meet different application requirements from various customers.
