What is the Difference Between Silicone Rubber and EPDM? Posted by Sally Yu  on May 21, 2018 When selecting a rubber for use, many Engineers end up needing to make a choice between selecting silicone or EPDM. We obviously have a preference for silicone(!) but how do the two match up against each other? What is EPDM and if you find yourself needing to choose between the two, how do you decide? Here is our quick-fire guide to EPDM… What is EPDM? EPDM stands for Ethylene Propylene Diene Monomers and it’s a type of high density synthetic rubber. It’s not as heat resistant as silicone but is able to withstand high temperatures up to 130°C. Because of that it’s used as a component within a wide variety of industries including industrial, construction and automotive. In lower temperatures, EPDM will reach brittle point at -40°C. EPDM is also popular as an outdoor rubber as it’s resistant to weathering including acid and alkali resistance. As such, you’ll typicall...

WHY USE SILICONE RUBBER? Posted by Sally Yu  on May 21, 2018 Silicone rubbers are rubber compounds with both organic and inorganic properties, as well as highly pure fumed silica as two main components. They possess many characteristics which are not present in other organic rubbers and have important roles in numerous industries, such as electrical, electronics, automobiles, food, medical, household appliances and leisure products. Silicone rubber is uniquely different from conventional rubber in that the molecule structure of the polymer consists of long chains of alternating silicone and oxygen atoms. This polymer therefore has an organic and inorganic nature. The inorganic part makes the polymer very resistant to high temperature and gives good electrical insulating properties and chemical inertness, while the organic components make it extremely flexible. Characteristics Heat Resistance: Silicone rubbers are extremely heat resistant as compared to normal...
