EPDM rubber rollers and nitrile rubber rollers differ in several aspects, as follows:
Composition
EPDM rubber rollers: The main components are ethylene, propylene, and non-conjugated dienes; it is a copolymer of ethylene and propylene.
Nylonitrile rubber rollers: They are produced by emulsion polymerization of butadiene and acrylonitrile.
Performance Characteristics
Oil Resistance: Nitrile rubber rollers have excellent oil resistance, while EPDM rubber rollers swell significantly in common mineral oils and lubricating oils, making their oil resistance inferior to EPDM rubber rollers.
High and Low Temperature Resistance: EPDM rubber rollers exhibit excellent high and low temperature resistance, with an operating temperature range of -60℃ to +150℃; nitrile rubber rollers have poor low-temperature resistance but better heat resistance, and their overall high and low temperature resistance range is not as wide as that of EPDM rubber rollers.
Aging Resistance: EPDM rubber rollers exhibit excellent resistance to ozone, UV radiation, weathering, and aging, ranking first among general-purpose rubbers; nitrile rubber rollers have poor ozone resistance, limiting their use in environments with high ozone concentrations.
Electrical Properties: Nitrile rubber rollers have inferior electrical properties; EPDM rubber rollers have excellent electrical insulation.
Elasticity: Nitrile rubber rollers have slightly lower elasticity; EPDM rubber rollers have good impact elasticity.
Application Scenarios
EPD (Ethylene Propylene Diene Monomer) Rubber Rollers: Due to their excellent weather resistance, high and low temperature resistance, and electrical insulation, they are suitable for applications requiring high environmental adaptability and use in various climatic conditions, such as outdoor equipment and electrical equipment.
Nitrile Rubber Rollers: With their outstanding oil resistance, they are widely used in applications involving contact with oils and solvents, such as printing and textile dyeing industries, for the production of various printing rollers and textile dyeing rollers.
