Solid silicone

Solid Silicone – Flexible and Resistant

Solid silicone, also known as silicone rubber, is a chemically inert, elastic material used mainly in industrial applications requiring resistance to extreme conditions. Also referred to as MVQ (siloxane polymers).

Advantages of Silicone

• Excellent electrical properties

• High elasticity and pressure damping

• Controlled gas permeability

• Resistance to torsion, compression, cracking

• Stability during long-term oxidation

• Operating temperature range: from −60 °C to +180 °C (temporarily up to +250 °C)

• Protection against UV, IR, ozone

• Steam resistance up to 3 bar

• Non-flammable, durable, compliant with food-grade standards

• Smooth and hygienic surface

• Resistance to a wide range of chemical substances

Technical Parameters

The manufacturer must test:

• Shore A hardness 50–70

• Tensile strength and elongation at break (DIN, EN, ASTM standards)

• Compression set according to DIN/BS

• Thermal conductivity (VDE)

• Brittleness temperature, UV resistance, electrical parameters, and operating range up to +180 °C

Food and Medical Certification

According to EU regulations, silicone may come into contact with food or skin only if it complies with FDA 21 CFR 177.2600 – this guarantees food-safe silicone.

Colors and Areas of Application

Available colors: white, transparent, black, brick-red. Applications include:

• Seals, gaskets

• Electrical and thermal insulation

• Food, medical, pharmaceutical, and packaging industries

• Construction and machinery industry

Usage Limitations

Silicone is not used with:

• Strong inorganic and organic acids/alkalis

• Esters, ethers, aromatics/fuel components (e.g. toluene, xylene), ketones (acetone), steam > 100 °C

Resistance to Operating Environments

Silicones perform well in contact with:

• Mineral oils, solvents, food-grade alcohols, water ≤ 100 °C, ozone, ammonia, margarine, vegetable oils, and low-concentration hydrocarbons

Silicone Sheets

Available dimensions: thickness 0.5–50 mm, width 10–1200 mm, length up to 10 m, Shore A hardness 5–90, and various colors.
