Sbr is widely used in tires shoe soles gaskets and even chewing gum.

Nr sbr rubber compound.

Welcome to our rubber chemical resistance chart. It maintains flexibility at lower temperatures. Styrene butadiene co polymer sbr is a synthetic rubber that is often substituted in part for natural rubber based on the comparative raw materials cost. Styrene content in the range of 10 25 contributing to good wearing and bonding characteristics.

Calcium carbonate 5 20 parts by weight. By 1929 german chemists at ig farben had developed a series of synthetic elastomers by copolymerizing two compounds in the presence of a catalyst this series was called buna after butadiene one of the copolymers and sodium. Sbr rubber compounds perform well in water alcohol silicone oil and grease non mineral oil based brake fluid and weak acids. Polybutadiene is used in combination with other rubbers because of its low heat buildup properties.

Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. Cleanout rubber sheets are uncured un vulcanized and show traces of polymers that were cleaned with the respective material. And 15 to 20. Use this rubber chemical resistance chart to make sure that the elastomer or o ring seal you choose will be compatible with the particular environment.

The materials have original tire compound s chemical additives because of that vulcanization time is long so its shelf life is long. Natural rubber 100 0 phr. Sbr is a product of synthetic rubber research that took place in europe and the united states under the impetus of natural rubber shortages during world wars i and ii.

The random copolymer has characteristics like natural rubber and contains. Halobutyl rubber is used for the tubeless inner liner compounds because of its low air. Sbr rubber compounds are susceptive to petroleum oils and fuels strong acids uv ozone mineral oils and aromatic aliphatic or halogenated hydrocarbons. Styrene butadiene rubber sbr has excellent impact strength good resilience tensile strength abrasion resistance and ageing stability.

While the butadiene unit is composed approximately 60 to 70 trans 1 4. Styrene butadiene rubber sbr or styrene butadiene is a synthetic rubber comprising of styrene and butadiene monomers.
