Choose the Right Material
In fact, rubber raw materials include NBR,HNBR,EPDM,FKM,Silicone，and Silicone（food grade），etc. Before determining the customization, we need to determine which rubber raw material to use. The properties and applicable scenarios of the raw materials may be very different.
VITON(FKM)
Working temperature: -20℃~200℃ Performance :High temperature resistance, chemical resistance, suitable for polar solvents. Application range: Often used in high temperature, chemical corrosion, oily environment, in metallurgy, chemical industry, automotive engineering, electric power and other industries.
EPDM
Working temperature: -50℃~150℃ Performance : Resistant to most oils and solvents (except ketones and esters). Application range: It is often used in the working environment that requires chemical corrosion resistance and oil resistance. It is widely used in the fields of metallurgy, chemical industry and automobile.
NBR
Working temperature: -40℃~120℃ Performance : Excellent oil resistance, water resistance, abrasion resistance, deformation resistance, but not suitable for polar solvents. Application range: Commonly used in fuel tanks, lubricating oil tanks, grease, silicone oil glycol series, used in oil, hydraulic leak-proof systems, etc.
Silicone(VMQ)
Working temperature: -70℃~220℃ Performance : Environmental protection, non-toxic, good elasticity, good electrical insulation properties, heat resistance, cold resistance, ozone resistance, atmospheric oxidation resistance; Poor tear resistance and friction resistance. Application range: Commonly used in household appliances, food machinery, daily necessities, toys and other industries that come into contact with people.
HNBR
Working temperature: -40℃~150℃ Performance: Upgrade on the basis of the performance of cyanide rubber, with higher working temperature, better wear resistance, alkali resistance, acid resistance, ozone resistance, Weather resistance, etc. Applications: Water seals, oil seals, hydraulic systems, etc.
PU
Working temperature: -40℃~90℃ Performance: Excellent wear resistance, good elasticity, high hardness, oil resistance and solvent resistance. Application range: widely used in machinery industry, automobile manufacturing, petroleum industry, mining industry, electrical and instrument industry, construction industry, medical and health and sports goods manufacturing and other fields.
