Epdm Rubber Material Properties

Epdm rubber ethylene propylene diene monomer rubber is a type of synthetic rubber that is used in many applications.

Epdm rubber material properties.

The epdm elastomer is one of the more interesting types of rubber. The diene is usually dicyclopentadiene ethylidene nobornene or 1 4 hexadiene. Blücher sealing rings are available in three different rubber qualities epdm nbr and fpm. 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.

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. The m class comprises elastomers having a saturated chain of the polyethylene type the m deriving from the more correct term polymethylene. Epdm is an m class rubber under astm standard d 1418. Ethylene propylene diene rubber epdm has polar fluid resistance heat resistance till 175 c low temperature flexibility and outstanding electrical insulation.

Discovered in the early 1700 s natural rubber material was presented to the royal science academy of france as a valuable resource interest. Epdm is made from ethylene propylene and a diene comonomer that enables. 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. 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.

With similar properties to silicone rubber below 250 degrees f epdm is resilient has low electrical conductivity and adheres easily to metals. The epdm properties that are listed below are for our most popular epdm 70 durometer 70a rubber material. 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. A lip sealing ring constitutes the seal between socket an spigot end.
