What are the characteristics of high temperature sealing silicone?

High temperature resistant silicone leather plate is a common performance silicone raw material for making silicone molds, and ordinary silicone sheets are resistant to high temperatures between 200 and 300 degrees Celsius. The maximum temperature can reach 400 degrees Celsius in a certain period of time, and it is often used for silica gel with special performance requirements. High temperature resistant silicone leather board characteristics 1, with good temperature adaptability (-60-330 degrees Celsius), aging resistance, adhesion, high and low temperature resistance, solvent resistance, acid and alkali resistance, more flexibility and other characteristics; 2. Good sealing performance, strong and durable, and can be reused; 3. Moisture-proof, earthquake-resistant, corona-resistant, anti-leakage, etc.

4. It is widely used in bonding and sealing with high temperature resistance requirements.

Main uses: 1.Electrical insulation: Silicone sheet has a high level of electrical insulation, can withstand high voltage load, and can be made into insulating cloth, sleeve and other products.

2.Silicone sheets can soften scars, prevent scar hyperplasia, and finally achieve the effect of reducing scars.

3.Anti-corrosion: Silicone rubber coated with glass fiber cloth, which can be used as an internal and external anti-corrosion layer for pipelines and deposits, with excellent anti-corrosion performance and high strength, and is an ideal anti-corrosion material. [1]

The main features of red leaf silicone high-temperature sealing silicone are:

1. Silicone rubber profiles, produced by imported or domestic silicone;

2. The profile can be used in the temperature range of -50 to +250 for a long time;

3. Working at high temperature will not pollute food and medicine, and the materials meet food standards;

4. The profile is soft, the hardness is not affected by the climate, and it has good aging resistance;

5. The specifications of the profile are complete, and they can also be matched with a variety of colors. If there are special specifications, you can negotiate and customize.

Generally, glass glue can withstand about 250 degrees. Cheap plasticizers will volatilize quickly above 100 degrees, causing the glass glue to lose its elasticity and become brittle and crack. At present, most of the silicone glass adhesives on the market are added with cheap plasticizers, and the short-term temperature resistance can be as high as 250 degrees, and the first-class silicone glass glue can be used for a long time below 200 degrees after being fully cured.

High-temperature resistant glass glue (also known as: high-temperature sealant, high-temperature resistant glue) refers to special glass glue that can withstand a certain temperature. Glass glue classification:

According to different materials, it can be divided into high-temperature resistant organic glue and high-temperature resistant inorganic glue; According to the classification of heat resistance temperature, it can be divided into resistance

High-temperature resistant glass adhesive is mainly suitable for bonding, repairing and sealing all kinds of parts under high temperature working conditions, and has the advantages of high bonding strength, good sealing performance and corrosion resistance.

Classification of sealants: 1. Ordinary anaerobic adhesive has a temperature resistance of 140 and is cured in isolation from air, such as threadlocking agent, cylindrical parts retaining agent, etc. 2. Silicone sealant, moisture absorption and curing, widely used, according to the model temperature resistance is between 150 -300, such as plane sealant, cylinder head high temperature sealant.

3. Adhesive sealant, two-component reinforcing agent reaction curing, rigid after curing, temperature resistance between -50 -250, suitable for surface damage, deformation and other occasions with large gaps, such as equipment fillers.

It depends on where the sealant is used, just using the brand I have used, such as Baiyun brand sealant, most sealants can withstand the temperature range after curing is generally between -50 and 150.

Some sealants can withstand high temperatures, and high-temperature sealants can be divided into organic and inorganic high-temperature sealants according to the type of material.

Most of the organic high-temperature sealants have the characteristics of water resistance and vibration resistance, and still have toughness or elasticity after the colloid solidifies, and the difference in product quality is mainly reflected in the different heat resistance temperatures.

Inorganic high-temperature sealants are not water-resistant, can only be used in dry places, and are hard after the colloid solidifies, and the brittleness is not the same.

Some sealants are able to withstand high temperatures and can be used in environments above 300 degrees. High-temperature sealants are divided into organic sealants and inorganic sealants according to the type of material.

Organic sealants have water resistance and vibration resistance, toughness and elasticity after curing, and there is a certain difference in heat resistance in the quality of their products.

Inorganic high-temperature sealants are not water-resistant, can only be used in dry places, and the colloids are hard after curing, and the vulnerability is different.

For the sealant with outstanding high temperature resistance, it can be used normally in an environment of more than 300 degrees.

In particular, high-quality adhesives can withstand high temperatures and can be used with confidence.

It does not matter even if it is exposed to high temperatures for a long time, and it is suitable for long-term use in environments of more than 300 degrees.

There are many types of sealants, and they are oxygen-resistant and can withstand temperatures between 100 and 200 degrees. Ultra-high temperature is still dominated by gaskets, and sealants are still not good.

What are the characteristics of high-temperature sealants? Will high-temperature sealants corrode electronic components? For your question, there are many types of sealants, some sealants have high temperature resistance, this sealant is more prominent in high temperature resistance, and belongs to a kind of sealant that relies on moisture vulcanization, this sealant has high temperature resistance, so the use of the field is still relatively wide, so in the process of use, if high or low temperature will corrode electrical components?

High-temperature sealant characteristics The high-temperature sealant has temperature-resistant performance after curing, and the performance will not change between minus 55 degrees and minus 200 degrees, and it still maintains good bonding performance, and the electrical components will not be degummed. High resistance.

Generally, anaerobic adhesive is resistant to 150 degrees, and some other brands say that it can withstand up to 230 degrees.

What are the characteristics of high-temperature resistant silica?

The high temperature resistance of silica gel can reach about 350 degrees.

The high temperature resistance of silica gel can reach about 350 degrees. The high temperature resistance of ordinary silica gel is between 200 degrees and 300 degrees, but there are some special silica gels, which can increase the high temperature resistance to about 350 degrees in a short period of two hours.

The performance characteristics of silicone

1. Silica gel has high temperature resistance and low temperature resistance

The molecular structure of the silicon atom in the silica gel is relatively unique, the methyl group is connected, and the molecule presents a helical structure, and the bond angle length is relatively large, so it has high thermal stability. In addition, the flexibility of silica gel is relatively good, so it has a low embrittlement temperature, which can meet the needs of minus 80 degrees Celsius.

2. Silica gel has chemical resistance

After the volatilization of oily or polar solvents, silica gel can quickly restore its properties to avoid softening or swelling, so it has good chemical resistance.

3. Low surface activity, physiological inertia

Silica gel is a semi-inorganic polymer material, which contains active compounds, and can be modified through special modification to increase the fire resistance, flame retardancy and aging resistance of silica gel.

4. Compression deformation resistance

Whether it is in a high temperature or low temperature environment, the compression resistance and deformation resistance of silica gel are relatively good, and the stable state that can be obtained will be better, and it can be processed according to the requirements of the market, such as the production of silica gel into a sealing rubber ring.

Heat-resistant silicone is a very commonly used silicone product, and the general silicone can withstand high temperatures of 200 to 300 degrees Celsius. Silica gel that can reach up to 350 degrees Celsius in a short period of time, e.g. two hours, is often used on silica gels with specific properties. This silicone can be customized according to the user's requirements.

Among many substances, silica gel belongs to the category of high temperature resistance. In terms of properties, ordinary silicone can withstand high temperatures of 200-300 degrees Celsius. In addition, in a short period of time (e.g. two hours), the maximum temperature of silicone is about 350 degrees Celsius.

If it is a high-temperature resistant silica gel, it can withstand temperatures of 300-500 degrees Celsius.

Silica gel, also known as silicate gel, is a highly active adsorption material and is an amorphous substance. The main component of silica gel is silica, which is chemically stable and does not burn.

Generally speaking, silica gel can be divided into two categories: organic silica gel and inorganic silica gel according to its properties and components. Inorganic silica gel is a highly reactive adsorption material.

Silica gel is divided into macroporous silica gel, coarse-pore silica gel, B-type silica gel, and fine-porous silica gel according to the size of its pore size. Because the pore structure is different, their adsorption properties are also different.

How many degrees can high-temperature resistant silica gel withstand.
