NBR Rubber Coated Metal Material GN3025-SPCC

Production from special procession of coating rubber overlaid evenly on the on the surface of metal core.

GN3025-SPCC

Description

GN3825-SPCC is a new kind of sealing material that was produced from special procession of coating rubber overlaid evenly on the surface of metal core.

Provide excellent performance of high-temperature resistance and durability. It has a relatively long shelf life than other traditional non-metallic sealing materials.

 Therefore, It was generally used in harsh environmental condition of extra pressure and ultra-temperature sealing requirement.
