EPDM Rubber Pad
EPDM Rubber (ethylene propylene diene monomer rubber), a type of syntheti rubber, is an elastomer characterized by a wide range of applications. This is an M-Class rubber where the ‘M’ in M-Class refers to its classification in ASTM standard D-1418; the M class includes rubbers having a saturated chain of the polyethylene type. Dienes used in the manufacture of EPDM rubbers are dicyclo-pentadiene (DCPD), ethylidene norbornene (ENB), and vinyl norbornene (VNB).EPDM rubber is closely related to ethylene propylene rubber: ethylene propylene rubber is a copolymer of ethylene and propylene, whereas EPDM rubber is a terpolymer of ethylene, propylene, and a Diene-component.
Properties Of EPDM Pads:
It has very good properties in cold and not region i.e. weather, ozone & water resistance at wide range of service temperature (50°C to 140°C) with good resilience properties at low and high temperature, excellent heat ageing properties and acid resistance properties.Tiger Rubber Co. produces all types of EPDM Solid Rubber and Sponge Rubber, also manufacturing EPDM Flame resistance profiles to give flame resistance upto 30 to 40 seconds at continuous burning. resistance at wide range of service temperature (50°C to 140°C) with good resilience properties at low and high temperature, excellent heat ageing properties and acid resistance properties.Rubber, also manufacturing EPDM Flame resistance profiles to give flame resistance up to 30 to 40 seconds at continuous burning.
What is an EPDM Rubber Pad?
An EPDM rubber pad is a sheet or block of Ethylene Propylene Diene Monomer (EPDM) rubber,cut or moulded to a required size and thickness. EPDM is a synthetic rubber known for its stabilityoutdoors and in damp conditions, which is why the pads are widely used to cushion, isolate, seal and protect equipment and surfaces.The pads are placed under machines,laboratory instruments, compressors, pumps and HVAC units to reduce vibration and noise, and they also serve as gaskets, insulating mats and flooring layers.

Where EPDM Rubber Pads Are Used?
Anti-vibration mounting for lab equipment, motors, pumps, compressors and generators.
• HVAC and outdoor units such as chillers and condensers, where weather exposure matters.
• Flooring and mats in gyms, play areas and walkways for cushioning and grip.
• Gaskets and seals for doors, panels, tanks and pipework.
• Electrical insulation mats in front of panels and switchgear.
Applications of EPDM Rubber Pad
EPDM vs Other Common Rubbers
EPDM leads where weather, ozone and water exposure are the concern. If the pad will contact oils or fuels, a nitrile (NBR) or similar oil-resistant compound is the better choice.
FAQs
EPDM resists water and moisture very well, so it is suitable for damp and outdoor areas.
Yes. EPDM is valued for resistance to sunlight, ozone and weathering.
No. Mineral oils and fuels make EPDM swell. Use an oil-resistant rubber in those cases.
It depends on load and the amount of isolation needed. Share the equipment weight and use case with the supplier for a recommendation.
Sheets can generally be cut to size, and custom shapes are common. Confirm availability with your supplier.
