material
1. EPDM
Epdm can resist heat, light, oxygen, especially ozone. Epdm is essentially non-polarity, polarity solution and chemicalresistant, bibulous 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
①High and low temperature resistant, working temperature can be 250ºC, good mechanical toughness; even if temperature drops to -196ºC also can keep 5% elongation.
②Corrosion – resistence to most chemical and solvents, showing inertia, strong acid resistance, water and various organic solvents.
③High lubrication – the lowest friction coefficient in solid materials.
④Non- adhesion – is the smallest surface tension in a solid material and does not adhere to any substance
EPDM
PTFE
Silicon
