Rubber properties

What are the properties of natural rubber? Named for its property as an eraser to rub out pencil marks, rubber is widely used. Use the rubber comparison chart to find the most economical seal. Or better yet, use the rubber chart to find which material will best suit your environment.

For example, if you need to find rubber compression properties , rubber weather resistance or even rubber ozone resistance for your O-rings, you can find the best combination of elastomer. Please use one of the following formats to cite this article in your essay, paper or report: APA.

Physical Properties of Rubber – a Buyer and Designer’s Guide. The most common properties of rubber are its elasticity, resistance to water and its use as an electrical insulator. Rubber is quite stretchy, as indicated by the nature of rubber bands. The final properties of a rubber item depend not just on the polymer, but also on modifiers and fillers, such as carbon black, factice, whiting and others.

Rubber particles are formed in the cytoplasm of specialized latex-producing cells called laticifers within rubber plants. Rubber compounding is a very broad and technical fiel since basic rubbers or elastomers are mixed with various chemicals and ingredients (and even with each other) to obtain desired physical properties. EPDM - Ethylene Propylene Diene Rubber.

Ethylene propylene diene monomer (EPDM) is a copolymer of ethylene, propylene and a small amount of non-conjugated diene monomers (– percent) which provide cross-linking sites for vulcanization: The diene is usually dicyclopentadiene, ethylidene nobornene, or hexadiene.

Natural rubber has been used as a versatile material in engineering for many years. It combines high tensile and tear strength with an outstanding resistance to fatigue. To achieve the properties required for a given products, raw natural rubber can be compounded. EPDM rubber (Ethylene Propylene Diene Monomer rubber ) is a high-density synthetic rubber primarily used for outdoor applications like rubber roofing. It has dynamic and mechanical properties between natural rubber and synthetic rubber.

We make it in America and Ship Worldwide. Make sure you review all of our other popular materials to ensure that the material you choose is correct for your application. Besides the material properties of a rubber mount, which is deducted by the structure of the recipe, it can be developed through constructively measurements of the elastic elastomer, so it could be perfectly adjusted to the required application. This type of synthetic rubber can be cheaply produced and has some good properties not found on natural latex materials.

The reason for the success of this synthetic rubber is, of course, its unique properties and diverse applications. Silicones are polymers with a Si-O-Si backbone. There are different types depending on functional groups in the structure and curing mechanisms. Key properties include thermal stability, chemical stability, electrical insulation and low toxicity.

Main applications are flexible seals, o-rings etc. EPDM (Ethylene Propylene Diene Monomer) EPDM seals and gaskets are well known for ozone, weathering and aging resistance. EPDM rubber also has excellent water and steam resistance, maintains its flexibility at low temperatures, features excellent resistance to alkalis, acids and oxygenated solvents, and is very color stable.

The fatigue resistance and low temperature properties of SBR are usually inferior to natural rubber , whereas its heat-aging properties and abrasion resistance are better. Like natural rubber , SBR is vulnerable to thermal and oxidative degradation due to the presence of double bonds in the polydiene backbone.
