Rubber-coated Metal Material (RCM)

Rubber Coated Metal Material -RCM

The type of sealing material applied uniformly rubber coating on the surface of base metal steel through a specific production process. It has good heat resistance and long-term durability, as well as a very low compression permanent deformation rate. Compared with traditional non-metallic sealing materials, RCM has relatively long service life, it is usually used in application for higher pressure, higher temperature and stricter sealing requirements.

Application recommendation:
●Cylinder Head Gasket                
●Small Engine Cylinder Gasket    
●Compressor gasket                     
●Water Pump/Oil Pump                  
●other Engine Gasket                    

RUBBER COATINGS

Nitrile Butadiene Rubber (NBR)

a synthetic rubber with excellent resistance to oils, coolant, fuel, refrigerant and other fluids. NBR offers superior abrasion resistance for metal steel adhesion. Heat resistance up to 200°C in clamped state application.

Nitrile Butadiene Rubber (NBR) Foamet

Same characteristics of NBR, with the special benefit of higher conformance to rough sealing surfaces and lower clamp load applications.

Fluoroelastomer Rubber (FKM)

Superior heat resistance and fluid immersion performance. Heat resistant up to 250°C in clamped state applications.

Foamed Rubber Metal Material  

Foamed Rubber: Nitrile Rubber, NBR
Base Metal: Cold rolled steel plate 0.20mm, 0.25mm
Overall Thickness: 0.6mm, 0.8mm, 1.0mm, 1.2mm

 

WHAT ARE THE BENEFITS OF FOAMED RUBBER METAL MATERIAL? 

◇ The spongy foamed rubber provides high sealing ability for the rough surface.
◇ With superior compression and recovery characteristics, it can make up for the sealing problems caused by the fluctuation and roughness of the flange surface.
◇ The gasket metal steel body makes narrow edge gasket much more stiffer and not easy to lead deformation and crack.

Application recommendation:
●Transmission                  
●Crankcase                        
●Water Pump/Oil Pump     
●other Engine Gasket and pads
