Vmq Silicone Rubber Properties

Compared to fluorocarbon rubbers fluorosilicones provide a much wider operational temperature range as they can reach temperatures up to 175 c and go as low as 70 c.

Vmq silicone rubber properties.

Physical properties are generally low but are at least retained at higher temperatures. These properties range from high temperature performance to durability excellent electrical insulation properties as well as its transparency. Silicone rubber vmq is generally considered inorganic meaning its backbone is not made up of carbon. Silicone elastomers are ideal for high and low temperature applications.

It has a fairly low tensile strength and a moderately high ductility among rubber materials. The mechanical and physical properties are very similar to vmq. However fvmq offer poor hot air resistance when compared with vmq. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost.

Vmq silicone rubber. The si o si backbone of silicones are stronger longer and more flexible than c o bonds found in organic rubber materials. It is not resistant to super heated steam. They have high heat and oxidative stability outstanding low temperature flexibility and are resistant to many chemicals weathering ozone and sunlight uv.

Electrical properties are excellent and resistance to weathering and ozone attack is outstanding. Silicone rubber pmq pvmq vmq pmq rubber is a thermoset elastomer or rubber material.

Silicone rubber is an elastomer rubber like material composed of silicone itself a polymer containing silicon together with carbon hydrogen and oxygen silicone rubbers are widely used in industry and there are multiple formulations.

Silicone rubbers are ideal for high and low temperature applications. For assistance in identifying the appropriate polymer or material or to develop and formulate a silicone rubber compound to meet your specific application and performance requirements please contact rahco rubber inc. This si o si backbone also accounts for silicone s low glass transition temperature and stability in uv and ozone environments. Industrial grades of silicone rubber are generally based on polydimethylsiloxanes partially substituted with other organic groups such as alkyl vinyl or phenyl which regulate respectively the processability reticulation and resistance to low temperatures.
