Silicone rubber has many unique qualities, which enable the extensive use of silicone rubber for different applications.
- The hardness area of silicone rubber is wide: 20 – 90 ShA. The higher the hardness value, the harder the product will be. The very soft materials (20 ShA) are used, for example, for sealing boxes that do not allow hard pressing.
- Silicone rubber also has a large operating temperature range. Regular qualities retain their properties between -50°C and +200°C Special qualities reach a resistance of -90°C. With additional materials, thermal resistance can even be increased up to 300°C.
- Silicone rubbers also include qualities that resist oil and chemicals. They can withstand a limited amount of acids and alkalines, among other things.
- Conducting silicone rubber can be used for EMI-shielding. In addition, various gaskets can be produced from a conducting material with an extruder.
- Colouring of silicone rubber is easy to make. Silicone rubber colours are silicone based and certain tones from the RAL colour chart are available ready-to-use. In addition, colours can be mixed by following the formula, if the ready-to-use tones are not suitable.
- Silicone rubber has a good ozone and UV light resistance, which allows silicone products to preserve their colour and elasticity even in strong sunlight.
- Flame resistant silicone rubbers include qualities with different classifications. Flame resistant silicones with especially high classification (BS standard) do not release poisonous gases. Ceramic powder will form on their surface during burning, protecting the rubber from being destroyed completely. These silicone rubber elements are used, for example, in underground railways.
- Silicone rubber products have FDA and BFR approvals, which allows these products to be used, for example, in contact with skin and food preparation or food production equipment. Silicone rubber is biologically inert.
