Different material for your reference
1.EPDM
Epdm can resist heat, light,oxygen, EPDM essentially non-polarity, polarity solution and chemical resistant, bibulous rate is low, it has good insulating properties.
2.Silicon
Insoluble in water and any solvent, non-toxic and tasteless, chemical properties stable, except strong alkali, hydrofluoric acid not react with any material.
3. PTFE
1.High and low temperature resistant, working temperature can be 250°C, good mechanical toughness;even if temperature drops to -196 degree also can keep 5% elongation.
2.Corrosion - resistance to most chemicals and solvents, showing inertia, strong acid resistance, water and various organic solvents.
3.High lubrication -the lowest friction coefficient in solid materials.
4.Non-adhesion -is the smallest surface tension in a solid material and does not adhere to any substance.
