Advantages: Reliable and reliable work, good repeatability, long service life, low cost, high tensile strength, high tear resistance, oil resistance, acid and alkali resistance, corrosion resistance, aging resistance, long service life, excellent air tightness.

The material composed of rubber sandwich membrane and rubber diaphragm is mainly made of rubber elastomers (nitrile, fluororubber, silicone, natural rubber, and other rubbers), and reinforced fabrics (nylon, glass fiber, Nomex, and other special reinforced fabrics) as the skeleton. Different elastomers and skeletons can be selected according to customer requirements to process rubber diaphragms of different thicknesses

1. It is also divided into pure rubber type and fabric (cloth) type according to its structure.

2. Divided by shape into circular, square, and flat stamping types.

3. According to the material, it can be divided into natural rubber NR, nitrile rubber NBR, silicone VQM, ternary rubber EPDM, fluorine rubber FPM/VITTON, etc.

4. Durable environments can be divided into solvents such as water resistance, oil resistance, acid and alkali resistance, toluene/propane resistance, natural gas and gas resistance, engine oil/gasoline (ethanol gasoline), etc.
