Standard Color: Blue Working Temperature Range: -30° C to + 110° C PU is premium polyurethane for superior sealing performance for use in general hydraulic applications (Not suitable for hot water), it has excellent mechanical properties such as high tensile strength, abrasion resistance, tear strength, and extrusion resistances.
Nitrile Rubber (NBR)
Standard Color: Black Working Temperature Range: -40° C to+ 100° C Nitrile Rubber is general purpose elastomer for Hydraulic and Pneumatic systems and used as seal energizer for low pressure applications such as pneumatic, it has excellent resistance to mineral oil, greases, water, hydrocarbon fuels, compression set resistance and good elastic properties, it is not suitable to automotive brakes fluid.
Standard Color: Black Working Temperature Range: -25° C to 150° C HNBR rubber, improves wear and extrusion resistance over standard NBR, HNBR has outstanding resistance to heat, ozone, weathering, mineral oil, crude oils, with amines, fuels, greases, aliphatic hydrocarbons, and industrial chemicals, it has very good mechanical properties and has extended high temperature range.
Standard Color: Orange/Dark Red Working Temperature Range: -60° C to+ 200° C Silicon Rubber has great cold flexibility as well as high thermal resistance. It has excellent de-electric properties and very good resistance to attack by oxygen, ozone and sunlight. It has poor strength & tear resistance to mineral oils.
Fluorinated Rubber FKM(Viton)
Standard Color: Brown Working Temperature Range: -30° C to+ 220° C Viton Rubber is excellent resistance to mineral oils, hot water, steam, fuels, alcohol, hot oils, aliphatic and aromatic hydrocarbon, it has poor resistance to methanol, ketones & esters also exhibits excellent chemical resistance for use in harsh environments such as phosphate esters.
PTFE / VIRGIN
Standard Color: White Working Temperature Range: -195° C+ 250° C Used mainly for o-rings, backup rings and machined parts used in special applications requiring chemical inertness and limited strength. Ideal for use in cryogenic applications PTFE/ Glass Filled PTFE Standard Color: Off-White Working Temperature Range: -195° C to +250° C Typical application: Used where there is a need for improved wear and increased coefficient of friction. Ideal for high dynamic applications e.g. high rotation pumps
