modulus of elasticity for rubber sealing compounds
Modulus of rigidity (MPa) Silicone rubber for low-temperature applications KE-136Y General purpose silicone rubber KE-951 Nitrile rubber Chloroprene rubber Chloroprene rubber deteriorates rapidly and discolors at temperatures between 150°250°C, but there is little change in silicone rubber
The Elastic (Storage) Modulus:Measure of elasticity of material. The ability of the material to store energy. The Viscous (loss) Modulus: state to a rubber state in an amorphous material Mechanical: Sheet Molding Compound Cure in Shear Sandwich 19.51MPa 40 60 80 100 120 140 & 0.001 0.01 0.1 1 10 100 V 03D 0.001 0.01 0.1 1 10 100 Modulus of Elasticity for Rubber Sealing Compounds Learn why knowing Modulus values can be helpful in choosing a compound for your application.
If you need properties that are slightly different than the ones listed below, we can compound the formulation of the rubber material so that the Nitrile rubber specifications suit your needs. Finding the correct material especially if you are using it for an O-ring seal is important as the seal can degrade easily if the material is not compatible. Physical Properties of Rubber Satori Seal CorporationAug 11, 2017 · An engineer was installing a rubber seal on a door. The rubber he used had high modulus. The door was hard to close because the rubber resisted being deformed. He then used a compound with low modulus that deformed easily allowing the door to close easily. Measuring Youngs Modulus. Youngs Modulus is measured during a Tensile Strength test.
Modulus of Elasticity; The Test. The Tensometer stretches a specimen, or dumbbell, cut from a sheet of rubber, until it breaks. During the test, the force required and length of the gauged section are measured continuously. These measurements are used to calculate the various results, which considers the actual dimensions of the test specimen. Section II Basic O-Ring Elastomersthe wild, on commercial rubber plantations or manufactured synthetically by the chemical industry. Today, more than 32 synthetic rubbers are known, the most important ones are listed in Table 2-1. Modern elastomeric sealing compounds generally contain 50 to 60% base polymer and are often described simply as rubber.
5. Designing with Rubber Stress versus Strain Modulus Modulus, as used by the rubber industry, refers to stress at a predetermined elongation, usually 100%. It gives a comparison for good extrusion resistance. Modulus normally increases with increase in hardness and is probably the best indicator of the strength of a compound, all other factors VITON® Fluorelastomers An overview - Rubber SEALING ELEMENTS Viton® O-rings ERIKS offers a large number of Genuine Viton® compounds for a wide range of sealing applications. Hereunder, youll find the most commonly produced types. Original VITON® compounds - main types Standard Compounds - VITON® A Type Description 51414:70°+-5° IRHD black and green:standard quality
Sep 05, 2019 · While Modulus and Durometer are somewhat related, there can be a pretty large variance in modulus values between two compounds of the same durometer. In an application that requires a rubber seal to be stretched into place, a low modulus compound might be considered to make assembly easier.
