RUBBER EPDM O-RINGS:
1.Excellent resistance to weathering and ozone, water and steam, with good performance in castor
and some phosphate ester based fluids. Its low and high temperature capability is good, having
excellent resistance to set with good resilience. Also high temperature braking systems employing
castor based fluids for mouldings subjected to weathering and ozone and for seals in chemical
plant due to its good chemical resistance.
2.IEPDM is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems
that use fluids having a glycol or silicone base. This results in a highly fluorinated elastomeric
compound with exceptional temperature resistance, compatibility with a wide range of aggressive
chemical combinations and outstanding resistance to permanent deformation.
Chemical resistance:
1.Hot water and steam up to 149℃ with special compounds up to 260℃.
2.Glycol based brake fluids (Dot3 & 4) and silicone-based brake fluids (Dot 5)upto 149℃.
3.Many organic and inorganic acids.
4.Cleaning agents, sodium and potassium alkalis.
5.Phosphate-ester based hydraulic fluids (HFD-R).
6.Silicone oil and grease.
7.Many polar solvents (alcohols, ketones, esters).
8.Ozone, aging and weather resistant.
