With excellent workability and physical property, but poor oil resistance, thermal resistance and ozone resistance, NR is generally used widely in tires, shoes, hose, belt and others. Rubber rollers made of NR are suitable for applications that need not thermal resistance, oil resistance but desire low cost.
SBR has similar nature and uses to NR. In Taiwan, TSRC began producing this synthetic rubber since 1967.
NBR is oil-resistant synthetic rubber, commonly known as Hycar, and widely used in printing rolls. It has excellent thermal resistance and abrasion resistance. In Taiwan, Nantex is one of the factories that has been producing NBR rubber.
CR is the synthetic rubber first developed by DuPont of US (commercially known as “Neoprene”), has extraordinary mechanical strength, wear resistance and elasticity, as well as adequate oil resistance, chemical resistance, thermal resistance and ozone resistance. It is widely used in normal industrial rubber rollers.
EPDM has poor impact resistant, but is excellent in resistance to polar solvents like ketones and esters. Also, it is of good thermal resistance and chemical resistance. Therefore, EPDM is widely used in rollers for surface treatment and printing and industrial rollers that are thermal or chemical resistant. Its drawback is poor wear resistance.
As another synthetic rubber developed by DuPont (commercially known as “Hypalon”), CR is excellent in thermal resistance, chemical resistance, ozone resistance, climate resistance and wear resistance. Its drawback is high price.
Scientifically called as Poly Urethane Rubber, PU has excellent mechanical property, wear resistance and solvent resistance, and has poor thermal resistance and alkaline resistance. It is generally manufactured by liquid-assisted injection molding and widely used industries like iron making, paper making and glazing.
IIR has polar solvent resistance, thermal resistance and chemical resistance but is poor in oil resistance, elasticity and workability. It is difficult to vulcanize and is generally used in inner tubes for cars. Rubber rollers of this material are used in printing rolls that are resistant to polar solvents and common thermal resistant industrial rollers.
