Epdm Rubber Material Properties

The lip sealing ring ensures quick and efficient jointing of the pipe system while providing a tight seal in case of both pressure and vacuum.

Epdm rubber material properties.

Epdm ethylene propylene diene rubber. This type of rubber also acts as a less expensive alternative to silicone as it can last for long periods of time with proper use. With its origins tracing back to the para rubber tree grown in south america wide spread appeal of this new viable product appealed to various nations for the unique material properties of rubber with little knowledge about the functions of this new. Discovered in the early 1700 s natural rubber material was presented to the royal science academy of france as a valuable resource interest.

Epdm rubber ethylene propylene diene monomer rubber is a type of synthetic rubber that is used in many applications. The epdm elastomer is one of the more interesting types of rubber. Epdm is an m class rubber under astm standard d 1418. The m class comprises elastomers having a saturated chain of the polyethylene type the m deriving from the more correct term polymethylene.

Blücher sealing rings are available in three different rubber qualities epdm nbr and fpm. With similar properties to silicone rubber below 250 degrees f epdm is resilient has low electrical conductivity and adheres easily to metals. Ethylene propylene diene rubber epdm has polar fluid resistance heat resistance till 175 c low temperature flexibility and outstanding electrical insulation. Ethylene propylene diene monomer epdm is a copolymer of ethylene propylene and a small amount of non conjugated diene monomers 3 9 percent which provide cross linking sites for vulcanization.

Epdm also known as ethylene propylene diene monomer is an extremely versatile material used in a variety of applications from automotive products to hvac parts. A lip sealing ring constitutes the seal between socket an spigot end. Chemically known as ethylene propylene diene monomer rubber it possesses many traits that are characteristic of conventional elastomers such as tear resistance a high tensile strength and a low compression set of course this doesn t set epdm products apart from other elastomers like sbr or nbr that also have similar. Rubber material selection guide epdm or ethylene propylene abbreviation ep epr ept epdm astm d 2000 classification aa ba ca da chemical definition ethylene propylene diene rrp compound number category 80000 series durometer or hardness range abrasion resistance impact resistance vibration dampening physical mechanical properties 30.

It s also very flexible with 600 elongation and a tensile range of 500 2500 psi while functioning well in temperatures from 50 degrees f 45 c to 350 degrees f 177 c. The epdm properties that are listed below are for our most popular epdm 70 durometer 70a rubber material.
