Gasket - materials
• The choice of rubber material depends on
– Fluids-chemical attack or not
– The combination of temperature and pressure
• Rubber materials change properties due to
– Time-the rubber relaxes
– Temperature-the rubber deteriorates
– Hardening by attack of oxidising agents(e.g., oxygen in air)
– Swelling or softening by absorption of chemicals in the fluids
• Common gasket types
– Nitrile – EPDM – FKM
• Nitrile (NBR)
• NBR (standard material) up to 110°C
• NBR-HT(hight temperature) up to 130°C
• NBR (FDA)-food grade for standard NBR
• NBR-HT(FDA)-food grade for high temperatures NBR
• NBR-LT-for low temperature inrefrigeration applications
•HNBR(hydrogenated) for duties where normal NBR swells and for higher temperatures up to 150°C, more expensive
–Resistant to :
Many hydrocarbons, fats, oils, greases, hydraulic fluids, sea water,chemicals.
–Attacked by :
Ozone (except PVC blends), ketones, esters, aldehydes, chlorinated and nitro hydrocarbons
• EDPM
• Standard material up to 150 °C
• EPDM (FDA)-food grade for EPDM.
–Resistant to :
Water, Animal and vegetable oils, ozone, strong and oxidizing chemicals.
–Attacked by :
Mineral oils and solvents, aromatic hydrocarbons.
• FKM, Fluorocarbon rubber
– Often called VITON (DuPont trade name) , used for aggressive chemical compounds
–Resistant to :
High temperature steam,aliphatic, aromatic and halogenated hydrocarbons, acids, animal and vegetable oils.
–Attacked by :
Ketones, low molecular weight esters and nitro containing compounds.
– Two different qualities usually used
• FKM A (VITON A)
• FKM G(VITON G) High performance and temperature resistance,much expensive than VITON A
