Silicone rubber is an excellent material for demanding conditions

Silicone profiles made of silicone rubber are perfectly suited for construction and metal industry applications. We can adapt its properties to fit various operating environments; the properties of silicone rubber include resistance to steam, pressure, moisture, chemicals and oils, UV and ozone, and electrical insulation. Silicone rubber has the best operating temperature range which makes it a perfect choice for transportation industries.

General properties of silicone rubber

-80 °C – +250 °C

Extruded hardness 10–80 ShA

Colours according to the RAL chart


In our collaboration with Honkarakenne, we had to consider many factors to provide the best possible profiles for log house construction. Read more about our collaboration.

Silicone for varying conditions

Silicone rubber has superior temperature resistance properties compared to other soft materials, which makes it the most common material for profiles used in fire doors, or in the door and window seals in rolling stock or maritime transportation with strict fire-safety regulations. It also has excellent UV/ozone resistance, making it a good option for window and balcony seals that need to be long-lasting.

Silicone rubber is resistant to steam, pressure, and moisture. Fluorosilicone is also resistant to various fuels and oils. Silicone has excellent electrical insulation properties.

Using various additives, we can adapt the properties of silicone to different operating environments. Such applications include special materials for the paper and pulp industries, where high-pressure and chemical resistance is key, or in the maritime industry where components may face harsh climates.

All profiles can be manufactured according to the RAL colour chart.

Foam silicone

Foam silicone allows for a soft seal and hard frame to be joined. Foam silicone stands out from our other profiles with its “spongy”, closed-cell silicone structure, which works almost like a foam mattress; it’s thick and sturdy, and holds its shape well, making it especially great for example insulating corners, where it provides support and keeps out the cold air and outside noise.

Long Service Life

Even though silicone as a raw material is not exactly recyclable, it has important advantages, like its long service life, that still makes it an ecological choice, especially when you get it from us. We at V.A.V. Group have the advantage of creating small to medium-sized batches, perfectly meeting the needs of manufacturers.
