We request that you confirm your website account is valid and verify your email address. EPDM Caps. EPDM is a copolymer of ethylene, propylene and a small amount of non-conjugated diene monomers (3% - 9%) which provide cross-linking sites for vulcanization (rubber hardening). Elongation: 600% Maximum. For this reason they are useful in external harsh environments. Marco Rubber & Plastics is an industry leader in custom sealing solutions that go beyond the limits of catalog commodities. What is EPDM? Life cycle analysis of EPDM produced with AMC technology shows that it has much lower environmental impact than producing Ziegler-Natta EPDM,(1) including: Lets talk about your EPDM needs. It is widely accepted around the world due to its excellent resistance to steam, water and heat, as well as ozone, sunlight, mild acidic, alkali and oxygenated solvents. Available in both bale and free-flowing pellet forms, the NORDEL EPDM portfolio is progressively expanding with new products tailored to meet specific customer and industry needs. It is cross-linked in the process of sulfur or peroxide vulcanization. EPDM has good resistance to nitrogen, potassium and sodium. and up to +180C (+355F) in steam. The noise can be alleviated using specialty coatings that are applied at the time of manufacture of the seal. 1.

[4], 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). Ethylene, propylene, and catalyst systems are polymerized in an excess of hydrocarbon solvent. Inner diameter: 25 mm - 102 mm. Thomas Regional are part of Thomasnet.com. With similar properties to silicone rubber below 250 degrees F, EPDM is resilient, has low electrical conductivity, and adheres easily to metals. Its versatility and excellent durability make it a top choice for all sorts of tasks, from sealing against water ingress to providing insulation in freezer room seals. Even though it's a tough material, that doesn't mean it has to be tough to work with. EPDM (ethylene propylene diene monomer) is a synthetic rubber made up of ethylene, propylene, and diene monomers. Company. History of EPDM Wire and Cable. 1.4-dioxane. If you are unsure of the compatibility of your chemical, we recommend testing a sample of the material in question with the chemical. Some stocks may require more than 5 phr if the formula is highly extended (up to 10 phr still shows little detriment to state-of-cure). It is an electrical insulator.As such, EPDM can be formulated to be resistant to temperatures as high as 150C, and, properly formulated, can be used outdoors for many years or decades without degradation.
