Inert materials of biological type are used for the manufacture of silicone seals. Siloxane rubbers serve as the basis for their creation. Thanks to this combination, the heat-resistant sealant for furnaces has unique properties and is used very widely in a wide variety of industrial areas. With the help of a silicone profile, various types of joints are sealed.
In the EU countries, high-quality raw materials of varying degrees of hardness and accuracy are used in the production of sealing elements.
Distinguishing Features
The heat-resistant silicone seal has the following qualities:
- The material is heat and frost resistant. This allows the products to be used both at very low (up to -65 oС) and high (+270 oС) temperatures.
- Sustainable. The safety of the material guarantees its inertness.
- Highly resistant to the sun (both light and radiation) and ozone.
- Excellent mechanical strength. This providesproduct durability.
- Elasticity..
- Excellent gas permeability, which is 15-20 times higher than analogues from rubbers of organic origin.
- Good chemical resistance and resistance to physiological fluids. Due to this, the seals do not react to the influence of water, even boiling water, as well as alcohols, phenols, fuels, s alt solutions.
- Resistant to all types of mineral and edible oils. This number includes vegetable, confectionery fats, and other similar substances.
In addition, silicone products have excellent dielectric performance and electrical insulation properties.
Specifications
Heat-resistant oven seal features features such as:
- Tensile elongation. Its performance is 200%.
- A - 55-65 arb. Shore hardness units.
- More than 60 kg/cm2 of nominal tensile strength.
- Resistance to repeated deformation.
- Low residual memory.
- Ultimate wear resistance.
- Greater flexibility.
- Incombustibility.
- The ability to "hold" tears and cuts.
Types of products
In order to be able to choose the most suitable heat-resistant seal for furnaces for a particular installation, manufacturers produce products with different sections:
- Round.
- Square.
- Rectangular.
- Profile.
- Custom.
This allows for the best possible temperature and sealing performance for various processes.
Scope of application
The most commonly used heat-resistant sealant for ovens in the confectionery and bakery industry. It is installed in smoking, proofing, drying cabinets. But this is not the whole list of areas where silicone products are used. Due to their properties and characteristics, they are installed as seals in the following units:
- In machines that process and manufacture food products. We are talking about the confectionery and meat and dairy industries.
- In pneumatic, fuel, hydraulic systems: they provide sealing of various types of joints.
- In vacuum systems operating in extreme temperature conditions.
- In gas exhaust equipment - for sealing and insulation.
- In autoclaves.
- In a variety of thermal equipment to ensure sealing.
Due to the fact that the heat-resistant seal for furnaces can serve as an excellent electrical insulating material, it is used for arranging electrical devices and electrical equipment. Also install silicone seals in:
- Heat chambers.
- Cutters.
- Smoke generators.
- Freezers and refrigerators.
- Openings for windows, doors, hatches, portholes in shipbuilding and mechanical engineering.
Sothe conclusion suggests itself: silicone seals are used wherever it is necessary to protect components from an electric field, heat, moisture, light, dust, cold, and also dampen vibrations, noise and vibration. Sealant for furnaces has shown itself excellently over a wide range of temperatures in different climatic zones.
