Buyer guide: FKM vs NBR vs EPDM: which rubber for seals and hoses?
Frequently asked questions
Which polymer is best for oil-resistant parts?
NBR is the usual choice for oil and fuel resistance; higher acrylonitrile content gives more oil resistance. For higher temperatures, ACM or FKM may be needed.
Do you stock EPDM for automotive hoses and profiles?
Yes, several EPDM grades suitable for hoses, weatherstrips and extruded profiles are regularly in stock.
Where can I buy EPDM or NBR rubber in Chennai?
Riddhi Polymers holds EPDM, NBR, SBR, BR, CR and silicone grades in stock in Chennai and supplies manufacturers across South India.
