Pharmaceutical Diaphragm NBR EPDM PTFE Gasket 2 years service life
Product performance:
• 100% pure PTFE sealing surface, providing a clean pollution-free sealing surface.
• A unique composite process which firmly sticks PTFE to the rubber elastomer, preventing delamination and leakage.
• They're the choice in the electronics industry, chemical plants, and pharmaceutical factories.
• Resistant to chemical media other than acid-base metals and elemental fluorine.
• Good rigidity, strength and compression, resilience, compensation performance, which can meet high pressure and harsh conditions.

Introduction:
(Sanitary metering pump diaphragm) Metering pump composite rubber diaphragm as the name suggests, two kinds of rubber materials compound together to form a rubber diaphragm. Composite rubber diaphragm including natural rubber + PTFE rubber or natural rubber + nylon cloth surface, which PTFE rubber + ordinary rubber composite together to form the rubber diaphragm is widely used in the market, this composite rubber diaphragm has another name, called PTFE composite rubber diaphragm.
Materials:
EPDM is suitable for hygienic applications where the operating temperature does not exceed 100 ° C
EPDM - short for Ethylene - propylene - diene Monomer, its main characteristics for superior elasticity, oxidation resistance, ozone resistance and corrosion resistance, the film is suitable for polar material and steam, also hot water, cold water, alkaline medium and non-concentrated acid. The temperature range of EPDM is not as good as PTFE, and it is suitable for sanitary grade applications where the operating temperature does not exceed 100℃. For example, purified water systems. It should be noted that EPDM membrane is not recommended to be used for mineral oil, plant and animal lipids, aliphatic series or aromatic hydrocarbons, furnace solvents or concentrated acids, because EPDM will swell when encountering organic matter.
FKM is suitable for high thermal temperature and high chemical stability environment
FKM - is the abbreviation of fluorine rubber, refers to the main chain or side chain carbon atom containing fluorine on the synthetic polymer elastomer. In addition to the high elasticity characteristic of rubber, the introduction of fluorine atoms also gives fluorine rubber excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance.
