Composite graphite gasket

The reinforced graphite gasket is made of high-purity expanded graphite sheet lined with metal mesh by rolling or molding.
Commonly used lining material: SS304, SS316 or wire mesh.
Carbon content is more than 98%.
It has natural graphite characteristics, high temperature resistance and high pressure, and can meet the requirements of various power machine gaskets and the as e-petrochemical industry.
Graphite gasket, also know known as: graphite composite gaskets, reinforced compressible graphite sheet, composite graphite plate, flange gaskets, valve gaskets, reinforced composite gaskets.

Product Description

Features of graphite gasket sheet:

1. Light weight: 30% lighter than the same size aluminum, 80% lighter than copper, easily molded, cut, and formed for different applications.
2. Compression ratio (%): RSB/222/15-35 RSB/232/35-55
3. Rebound rate (%): RSB/222/≥20 RSB/232≥10
4. Temperature resistance vector (%): 450°C/2h 600°C/2h RSB/222≤1.0 RSB/232≤1.0
5. Oil rate (%): diesel ≤ 20 oil ≤ 20
6. Easy to transport: reinforced graphite composite board without gap plate, suitable for all kinds of long-distance transportation.
