Product Description
Molded rubber diaphragm NR/EPDM/SBR/NBR/CR, manufacture NBR/CR/NR/CSM/VITON/EPDM rubber diaphragm

Commercial Grade Neoprene rubber is an excellent general purpose polymer for most applications.  This grade of rubber is used as a barrier or gasket material and can also be used inside rooms for sandblasting and impact resistance for industrial needs.
Commercial Grade Neoprene is known for its resistance to oil, gasoline, sunlight, ozone and oxidation material providing excellent cold temperature flexibility, abrasion resistance, repeated flexing applications, wide temperature range and has a physical toughness.

We can make diaphragms of various sizes, in different shapes in Natural, Neoprene, EPDM, Silicone and Viton rubber.

1) Available material: Material for NBR, FKM, FPM, VITON(FKM)&Dow elastomers, Neoprene, HNBR, Natural rubber, SBR, IR, IIR(butyl rubber), ACM ect. KTW approved for material EPDM.

2) All manufacturing processes confirm to the ISO/TS16949, SGS, RoHS, REACH

3) Customer's design and specifications are accepted.

4) Color and shape can be changed upon request. Available in various sizes and colors.

5) Our professional R&D team can provide you higher quality products with competitive price and all documents such as PPAP, CONTROL PLAN, PFMEA etc.

6)Have advanced CNC machine and technique to cut bonding washer molds by ourself.

7)Responds very well with resistance to ozone, high temperatures, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. The universal O-ring.

8)Widely used in automobile, electrical appliances and other industry. Good function of sealing and attenuating shock
9) EPDM70 Black (E7001Z59) can meet WRAS KTW DVGW(W270), and have all the certificates.

A diaphragm seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained. Diaphragms are also used to protect a process fluid from the pressure sensor.
