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.
Vmq silicone rubber properties.
Physical properties are generally low but are at least retained at higher temperatures.
They have high heat and oxidative stability outstanding low temperature flexibility and are resistant to many chemicals weathering ozone and sunlight uv.
Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost.

Complete guide on highly durable elastomer silicone rubber is a high performance elastomer characterized by an unusual combination of properties.
It has a fairly low tensile strength and a moderately high ductility among rubber materials.
These properties range from high temperature performance to durability excellent electrical insulation properties as well as its transparency.
Silicone rubber vmq and fvmq is a highly versatile elastomer that can be used in many diverse sectors.
Silicone elastomers are ideal for high and low temperature applications.
Silicone rubber vmq is generally considered inorganic meaning its backbone is not made up of carbon.
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.

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.

However fvmq offer poor hot air resistance when compared with vmq.
This si o si backbone also accounts for silicone s low glass transition temperature and stability in uv and ozone environments.
It is not resistant to super heated steam.
Electrical properties are excellent and resistance to weathering and ozone attack is outstanding.
The mechanical and physical properties are very similar to vmq.
