EPDM Rubber Gaskets

From the rooftops of our homes to the cars we drive every day, EPDM has cemented its place as one of the most versatile and common rubber elastomers on the market today. This synthetic material can tackle many tricky chemicals, tough insulating applications, and with stand the best Mother Nature can throw at your project.

Blaylock Gasket & Packing is proud to be your preferred source for EPDM (Ethylene Propylene). We proudly stock Ethylene Propylene in a wide variety of thicknesses, durometer, and sizes to create the perfect EPDM gaskets for you. Whether you need sheets, rolls or custom gaskets, EPDM may be an ideal material for your specific application. As always, we partner with massive corporations, but we’re proud to be small business-friendly, refusing to hold our customers hostage by excessive minimums.

What is EPDM?

EPDM is the shortened acronym for Ethylene Propylene Diene Monomer. EPDM rubber has excellent resistance to ozone, steam, strong acids and alkali. Not recommended for use with solvents and aromatic hydrocarbons. There are different grades of EPDM and we would be happy to help you select the proper material to ensure an adequate seal. We also offer EPDM extrusions, molded parts and O-Rings.

What are the advantages of EPDM?

TOUGHNESS: One of EPDM’s main strengths lies in its ability to handle the great outdoors. EPDM resists aging when exposed to harsh conditions like weather, UV and higher temperatures. EPDM also can offer lower electrical conductivity. Peroxide-cured EPDM offer even higher temperature and chemical resistance.

AFFORDABILITY: While there are some chemicals and environments where EPDM would not be a good choice (always check with our team) EPDM is cheaper than many other high-temp and chemical resistant materials.

VARIETY: If dimensional stability is required, we offer a nylon reinforced EPDM. Need a seal in the kitchen, Blaylock offers a white FDA EPDM. We run the gambit on EPDM materials – from commercial grade to mil-spec EPDM. Our NSF 61 rated EPDM is perfect for potable water applications in places like bottling plants, water departments, water storage facilities and treatment plants.

Types of EPDM

Blaylock offers a wide variety of EPDM materials – our team is ready to help you find the ideal material. We can custom compound EPDM as well.

COMMERCIAL GRADE EPDM

Our most economical EPDM, but a superior material, nonetheless. For most applications where EPDM is required our commercial grade product will do the trick.

COMMERCIAL EPDM BY THE NUMBERS
COLOR	DUROMETER	TEMPERATURE	THICKNESS
Black	40-70	-30 to 200F	1/32” to 1”

These numbers are a general guide and are subject to change at any time. Our team offers materials to meet any project. If you have special requirements for things like color, tensile, temperature, durometer, etc, please reach out to our team. Just because material listed doesn’t meet your spec does not meet it is not available.

Properties and application parameters shown throughout this datasheet are typical. Your specific application should not be undertaken without independent study and evaluation for suitability. For specific application recommendations consult Blaylock Gasket. Failure to select proper sealing products could result in property damage and/or serious personal injury.

FOOD GRADE EPDM

Our white FDA EPDM is manufactured with FDA white list ingredients per FDA Title 21 of CFR177.2600. It is non-marking and a popular choice in food and pharmaceutical applications. It is a superior, long-life sheet designed specifically for general gasketing, countertops and skirting in all areas of food processing and pharmaceutical and cosmetics manufacturing.

WHITE FDA EPDM BY THE NUMBERS
COLOR	DUROMETER	TEMPERATURE	THICKNESS
WHITE	60 (others available)	-30F to 200F	1/16” to ¼”

CLOTH-INSERT REINFORCED EPDM

We reinforce our quality EPDM material with a 5oz Nylon to offer greater dimensional stability and strength.

CLOTH-INSERT EPDM BY THE NUMBERS
COLOR	DUROMETER	TEMPERATURE	THICKNESS & PLY
Black	60	-30F to 200F	1/16” to ¼” (1 & 2 Ply Available)

PEROXIDE CURED EPDM

Most EPDM materials are sulfur cured. Blaylock offers a superior peroxide-cured EPDM product for added strength and resistance. Peroxide curing ups the temperature resistance, reduces aging and improves compression set data. Peroxide cured materials also offer increased chemical resistance in many applications. Our team can help determine if you need this exceptional product.

PEROXIDE CURED EPDM BY THE NUMBERS
COLOR	DUROMETER	TEMPERATURE	THICKNESS
Black	60	275 -300F (Depends on Compound)	1/16” to ¼”

NSF-61 RATED EPDM

Formulated for applications where gasketing encounters potable water. This material is sulfur cured and is available in smooth and fabric finish. This material meets ANSI/AWWA C111/A21.11 and ASTM D1330

NSF 61 EPDM BY THE NUMBERS
COLOR	DUROMETER	TEMPERATURE	TENSILE
Black	75	-20 to 250F	1500psi

SPEC GRADE EPDM
