What is silicone rubber

Silicone has – in contrast to rubber – an indivisible structure. The shape of silicon rubber does not change under the influence of heat, cold or dryness, which is why it is widely used in the pharmaceutical, medical and food industries. Just like NBR rubber and SBR rubber, silicone rubber is also a synthetic rubber.

What are the properties of silicone rubber?

Silicone rubber can well withstand temperatures up to 160°C. It is highly weather-resistant, has outstanding elasticity and can be produced in any colour (even transparent). The material is not resistant to oil, fuel, acids and bases. It has a low wear resistance and tensile strength, attracts dust and is a static product.

Silicone rubber can be produced with a low hardness so that it remains ‘soft’ and highly flexible. In addition, it possesses good electrical resistance and silicon gloves are therefore often used for electrical operations.

What are the applications for silicone rubber?

The pharmaceutical and medical industries often use silicone rubber, amongst other materials, for the application of breast implants and anaesthetic face masks. The food industry also uses silicone rubber, e.g. for closing rings in children’s drinking cups or to store food in closed containers (flexible silicone covers).  Silicone sealant is also widely known: it is water-proof, can withstand high temperatures and reduces mould formation. It is often used in kitchens and bathrooms.
