Silicone Rubber (VMQ)

Rubber

Silicone rubber, also known as VMQ (Vinyl-Methyl-Silicone), is a high-performance elastomer that excels in temperature resistance, flexibility, and chemical inertness. The material retains its elastic properties over a wide temperature range and is resistant to ozone, UV radiation, and aging. This makes silicone rubber ideal for applications in the medical sector, food industry, electronics, and aerospace.
Well-known trade names for silicone rubber include Silastic®, Elastosil®, Nusil®, and Silbione®. These grades are used worldwide in applications where high performance and reliability are essential.

Properties of Silicone Rubber

Exceptional temperature resistance from -60 °C to +230 °C (short-term up to +250 °C)
Excellent flexibility and elasticity, even at low temperatures
High resistance to ozone, UV radiation, and weather
Chemically inert and biocompatible, suitable for medical and food applications
Low compression set, maintains shape under long-term load
Electrically insulating properties, suitable for electronic applications
Available in various colors and hardness levels (Shore A 10–90)
Resistant to steam and hot water
Long lifespan with minimal maintenance

Thanks to these properties, silicone rubber is a reliable choice for applications where durability, flexibility, and resistance to extreme conditions are essential.
