Epdm Rubber Material Properties

Epdm is an m class rubber under astm standard d 1418.

Epdm rubber material properties.

Epdm is made from ethylene propylene and a diene comonomer that enables. Epdm rubber ethylene propylene diene monomer rubber is a type of synthetic rubber that is used in many applications. Discovered in the early 1700 s natural rubber material was presented to the royal science academy of france as a valuable resource interest. Blücher sealing rings are available in three different rubber qualities epdm nbr and fpm.

The diene is usually dicyclopentadiene ethylidene nobornene or 1 4 hexadiene. Epdm ethylene propylene diene rubber. 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. The m class comprises elastomers having a saturated chain of the polyethylene type the m deriving from the more correct term polymethylene.

If you need epdm properties that are different than the ones shown in the chart below we can reformulate the compound of the epdm material so that the epdm rubber specifications suit your needs. 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. 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. A lip sealing ring constitutes the seal between socket an spigot end.

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. With similar properties to silicone rubber below 250 degrees f epdm is resilient has low electrical conductivity and adheres easily to metals. 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. The epdm properties that are listed below are for our most popular epdm 70 durometer 70a rubber material.

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.
