Rubber Compression Molding Photogallery EPDM is short for the chemical formulation name known as Ethylene propylene diene monomer. While Ethylene Propylene Diene Monomer, or more commonly known as EPDM, gasket properties stem from its synthetic and inorganic composition, these industrial rubber gaskets are created for nature! Rubber News Furthermore, EPDM materials are far less costly and more durable than silicone materials. EPDM’s dynamic and mechanical properties are, in general, between natural rubber and SBR. This synthetic rubber is actually able to retain high elasticity and flexibility despite cold temperatures. Rubber Molding Industries, Qualiform, LLC EPDM is one of the most commonly used rubber elastomers in the world and can be manufactured in a variety of different processes including continuous extrusion, molded products, O-rings, and die-cut. Sulfur-cured EPDM is the least costly and provides better tear and abrasion resistance compared to peroxide-cured compounds. Able to withstand such harsh conditions, EPDM has definitely proved itself as the material to beat for any outdoor applications. EPDM Sheet Rubber. Everything You Wanted to Know About FDA Approved Rubber! However, it should not be used in applications involving contact with petroleum products, food-based applications or applications with continuous exposure to aromatic hydrocarbons. A Rubber Bumper Protects Property From Damage!

Qualiform offers custom rubber molding services, rubber compression molding, rubber injection molding, rubber transfer molding, and rubber to metal bonding. Of course the latter is contingent on the actual EPDM rubber and gasket product EPDM is available in a variety of blends, durometers, and tensile strengths. 1999 - 2019 Rubber-Cal All rights reserved. The molecular structure contains a single bond, which is what provides EPDM these strong characteristics. Developed in the 1950’s, EPDM was designed specifically for the Middle East because of the large range of temperature fluctuations that occur in the desert. Here are the most important reasons for buying EPDM rubber and gasket products: Can be produced in an assortment of durometers. Rubber Durometer Chart – From Soft to Hard. EPDM provides superior properties for outdoor and high temperature applications. EPDM offers exception resistance to UV, ozone, weathering, aging and various chemicals, Offers stability in extreme high and low temperatures, Versatility allowing for use in many industries and applications, Durability and longevity for continuous use, ASTM D-2000 Classification AA, BA, CA (Standard Classification System for Rubber Products in Automotive Applications), Chemical Definition: Ethylene Propylene Diene Monomer, Adhesion to Rigid Materials: Good – Excellent, Organic Acids (Concentrated): Fair – Good, Non-Petroleum Based Brake Fluids: Good – Excellent, Halofluorocarbons Refrigerant: R-12, R-13, Halofluorocarbons Refrigerant with Oil: Poor, Minimum for Continuous Use (Static): -60ºF, Maximum for Continuous Use (Static): +300ºF. Show Ethylene Propylene Diene Rubber (EPDM) materials with Elongation of 150 - 800 % at 20 °C, Show Ethylene Propylene Diene Rubber (EPDM) materials with Tensile strength of 5 - 33 MPa at 20 °C, Sealing profiles, O-rings, hoses, cable sheathing, Compression molding, extrusion, vulcanization. Rubber to Metal Bonding - saving you, Thermally Conductive Sealants & Adhesives, Electrically Conductive Silicone Sealants & Adhesives. The EPDM properties that are listed below are for our most popular EPDM 70 durometer … 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). EPDM rubber remains effective in a temperature range of -54 degrees Celsius to 150 degrees Celsius. It is often used for applications that are exposed to outdoor or high heat environments. Technical Properties of EPDM; Polymer Properties: Specific Gravity: 0.87: Shelf Life: One Year: Pot Life: 3-4 Hrs depending on temperature. As a top EPDM rubber products manufacturer, Qualiform offers unmatched processing, development and testing capabilities. EPDM is a uniquely versatile, general purpose rubber. Rubber Extrusion Process EPDM compounds are frequently used with foods, water, steam and phosphate ester fluids (Skydrol) applications and offer the excellent resistance to brake fluids (glycol base), weather, and ozone. This makes them ideal for electrical applications as well because they insulate the electrical currents from water to avoid any dangerous situations. EPDM gasket material is one of the few rubbers that can repel ambient heat and ozone rays effectively. We also use them to provide you more relevant information and improve our platform and search tools. Sold in blended (less expensive) or 100% EPDM versions. Finding the correct material especially if you are using it for an O-ring seal is important as the rubber can degrade quickly if the material is not compatible with your environment. Neoprene Rubber For example it is used an industrial rubber and gasket seal where steam is present, which is generally outdoor. EPDM also exhibits mechanical properties found in both natural rubber and synthetic rubber. Rubber Gaskets and Seals Physical & Mechanical Properties / Chemical Resistance / Thermal Properties / Environmental Performance / EPDM Rubber Applications. Rubber Injection Molding It is an ideal roofing material as well as many other outdoor, HVAC, automotive and industrial applications. While this rubber material is chemically designed to be well-adjusted to outdoor settings, it does not give up any of the beneficial properties of natural rubber. This site uses cookies. Our expert technical staff is available for consultation in regard to design and property requirements for customers looking to develop a recycling star for their application or media processing. In other words one EPDM part may not be anything like another just because they both have EPDM content. For the best experience on our site, be sure to turn on Javascript in your browser. Factors Affecting Rubber Tolerances L IMITATIONS : EPDM is not recommended for use with petroleum oils, fluids, or solvents because significant swelling would result. Matmatch uses cookies and similar technologies to improve your experience and measure your interactions with our website. Luckily this can be somewhat remedied by applying a specialty coat to increase the chemical resistance of EPDM. List your company on Matmatch now and reach engineers around the world looking for such materials. Whether to help homes weather out storms or … breaking down, becoming brittle, etc. ASTM D2000-01 Grade M5CA714 A25 B35 C32 EA14 F17 G21, ASTM D2000-75 Grade5CA720 A25 B35 C32 L14 F17 G21. EPDM is a synthetic rubber elastomer that exhibits outstanding ozone, weather, and heat resistance and has excellent electrical insulating properties. It is often used for applications that are exposed to outdoor or high heat environments.
