Heat-resistant sealant for furnaces: features, characteristics, application

For the manufacture of silicone seals inert materials of a biological type are used. The basis for their creation are siloxane rubbers. Thanks to this combination, the heat-resistant sealant for furnaces has unique properties and is used very widely in various fields of the industrial sphere. Compounds of various types are sealed with a silicone profile.

In the EU countries, the production of sealing elements uses high-quality raw materials of varying degrees of hardness and accuracy.

Distinctive features

Heat-resistant silicone sealant has the following qualities:

1. The material is heat and frost resistant. This allows the use of products both at very low (up to -65 ^o ), and at high (+270 ^o ) temperatures.
2. Environmental friendliness. The safety of the material guarantees its inertness.
3. High resistance to the effects of the sun (both light and radiation), as well as ozone.
4. Excellent mechanical strength. This ensures product longevity.
5. Elasticity. ^.
6. Excellent gas permeability, which is 15-20 times higher than the analogs of rubbers of organic origin according to these indicators.
7. Good chemical resistance and resistance to liquids of physiological types. Due to this, seals do not respond to the influence of water, even boiling, as well as alcohols, phenols, fuels, saline solutions.
8. Resistance to all types of mineral and edible oils. This number includes vegetable, confectionery fats, and other similar substances.

In addition, silicone products are characterized by excellent dielectric characteristics and electrical insulating properties.

Specifications

Heat-resistant sealant for furnaces is characterized by such properties as:

1. Elongation at elongation. Its performance is 200%.
2. A - 55-65 conv. Shore hardness units.
3. More than 60 kg / cm2 of conditional tensile strength.
4. Resistance to repeated deformation.
5. Low residual memory.
6. Extreme durability.
7. Great flexibility.
8. Incombustibility.
9. The ability to "hold" tears and cuts.

Types of products

In order to be able to choose a heat-resistant seal for furnaces that is most suitable for a particular installation, manufacturers produce products with different cross sections:

1. Round.
2. Square.
3. Rectangular.
4. Profile.
5. Non-standard.

This allows you to ensure maximum preservation of the desired temperature and tightness during various processes.

Application area

Most often they use heat-resistant sealant for ovens in the confectionery and baking sector. 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 sealants in the following units:

1. In apparatuses processing and manufacturing food products. It is about the confectionery and meat and dairy industry.
2. In pneumatic, fuel, hydraulic systems: with their help provide sealing of connections of various types.
3. In vacuum systems operating in extreme temperature conditions.
4. In gas extraction equipment - for sealing and insulation.
5. In autoclaves.
6. In a variety of thermal equipment to ensure sealing.

Due to the fact that the heat-resistant sealant for furnaces can serve as an excellent insulating material, it is used to equip electrical devices and electrical equipment. Silicone seals are also installed in:

1. Heat chambers.
2. Cutters.
3. Smoke generators.
4. Freezers and refrigerators.
5. Apertures of windows, doors, hatches, portholes in shipbuilding and engineering.

So, the conclusion suggests itself: silicone seals are used wherever it is necessary to protect the components from the electric field, heat, moisture, light, dust, cold, and also dampen vibrations, noise and vibration. Sealant for furnaces proved to be excellent with a wide range of temperature indicators in different climatic zones.
