What Is a Silicone Rubber Sheet?
A silicone rubber sheet is a flat elastomer material manufactured from silicone rubber and supplied in rolls, lembaran, strips, or custom-cut shapes.
Silicone rubber is based on a silicon-oxygen polymer backbone, which gives it a combination of:
High and low temperature resistance
Flexibility and elasticity
Good weather resistance
Ozone resistance
ketahanan terhadap sinar UV
Electrical insulation
Good aging resistance
Low moisture absorption
Good sealing performance
The exact properties depend on the silicone compound, kekerasan, ketebalan, reinforcement, curing method, and manufacturing process.
Key Features of Heat Resistant Silicone Rubber Sheet
1. High Temperature Resistance
One of the main reasons manufacturers select silicone rubber is its ability to maintain useful physical properties at elevated temperatures.
Typical silicone rubber sheet grades can withstand temperatures significantly higher than many general-purpose elastomers. Depending on the formulation, industrial silicone sheets may be designed for continuous service around-50°C to +200°C, with specialized grades offering higher temperature capability.
The actual continuous and intermittent temperature limits should always be confirmed according to the technical data sheet for the selected grade.
This makes silicone rubber sheet suitable for applications involving:
Heating equipment
Thermal sealing
Ovens
Industrial machinery
Electrical equipment
Automotive components
Heat-resistant gaskets
Thermal insulation
2. Flexible and Elastic
Silicone rubber remains flexible over a wide temperature range.
This flexibility allows the material to:
Bend around curved surfaces
Conform to irregular surfaces
Absorb vibration
Maintain sealing contact
Accommodate thermal expansion
Provide cushioning between components
For applications requiring repeated movement or compression, silicone rubber can provide a useful combination of elasticity and dimensional stability.
3. Good Tear Strength
Silicone rubber can be formulated for improved mechanical performance, including good tear resistance.
Tear strength is particularly important when a sheet is:
Cut into gaskets
Installed around holes
Bent repeatedly
Compressed between components
Exposed to mechanical handling
Used around corners or irregular edges
For demanding mechanical applications, the appropriate silicone grade should be selected based on the required tensile strength, elongation, kekuatan sobek, kekerasan, and operating temperature.
4. Excellent Weather Resistance
Silicone rubber has good resistance to environmental aging and is widely used in outdoor and exposed applications.
It generally offers good resistance to:
UV radiation
Ozone
Weathering
Oxidation
kelembaban
Temperature fluctuations
This makes silicone rubber sheet suitable for equipment exposed to sunlight, outdoor environments, and changing temperatures.
5. Electrical Insulation
Silicone rubber is also used as an electrical insulating material.
Depending on the grade and application, silicone sheets can be used for:
Electrical insulation
Cable protection
Electrical enclosure sealing
Transformer components
Electronic equipment
Heat-resistant insulating pads
For electrical applications requiring specific dielectric, flame-retardant, or regulatory performance, the exact grade and test requirements should be specified before production.
Heat Resistant Silicone Rubber Sheet Applications
Industrial Gaskets and Seals
Silicone rubber sheet is commonly converted into gaskets, sealing pads, and custom seals.
It can be used to create:
Flat gaskets
Flange gaskets
Equipment seals
Access-panel seals
Heat-resistant sealing pads
Custom die-cut seals
Its flexibility allows the material to conform to mating surfaces while maintaining sealing contact.
Heat-Resistant Pads
Silicone rubber sheet can be used as a protective or insulating pad around equipment exposed to heat.
Aplikasi termasuk:
Heat-resistant machine pads
Thermal barriers
Heating equipment
Heat press equipment
Industrial ovens
Heat-resistant spacers
The appropriate thickness and silicone grade should be selected according to the temperature and mechanical load.
Aplikasi Otomotif
Silicone rubber is widely used in automotive and transportation applications because of its temperature stability, fleksibilitas, and environmental resistance.
Potential applications include:
Engine compartment seals
Heat-resistant gaskets
Protective pads
Electrical insulation
Vibration isolation
Sealing components
The selected compound must be compatible with the specific automotive environment, including temperature, minyak, fuels, coolants, and other fluids.
Electrical and Electronic Equipment
Silicone rubber sheet can combine flexible sealing with electrical insulation.
Typical applications include:
Electrical equipment seals
Insulation pads
Electronic component protection
Enclosure gaskets
Heat-resistant electrical barriers
For electrical applications, customers should specify required dielectric strength, flame-retardant requirements, and applicable standards.
Food and Processing Equipment
Certain silicone rubber compounds are available for applications involving food processing and contact with specific substances.
Namun, not every silicone rubber sheet is food grade.
If the product will directly contact food, drinking water, pharmaceuticals, or other regulated materials, the required regulatory standard must be confirmed before production.
Silicone Rubber Sheet Specifications
We can provide silicone rubber sheets in different specifications according to the application.
Lembaran karet silikon merahis one of the most recognizable industrial silicone sheet products and is frequently used for gaskets, sealing components, heat-resistant pads, dan aplikasi industri.
Other colors can also be manufactured according to the required application or visual identification system.
How to Select the Right Silicone Rubber Sheet
Selecting the correct silicone sheet requires more than simply choosing a thickness and color.
1. Temperature
Provide:
Minimum operating temperature
Normal operating temperature
Maximum continuous temperature
Maximum intermittent temperature
Temperature is one of the most important factors when selecting a silicone rubber compound.
2. Kekerasan
Silicone rubber sheets can be produced in different hardness levels.
A softer silicone sheet may be suitable for:
Sealing
Bantalan
Low-pressure gaskets
Flexible pads
A harder grade may be preferred for:
Structural support
Higher compression resistance
Mechanical applications
Dimensional stability
3. Ketebalan
Thickness should be selected according to the required sealing, isolasi, bantalan, and mechanical performance.
Thin silicone sheets are useful for:
Electrical insulation
Thin gaskets
Protective layers
Thicker sheets are suitable for:
Bantalan
Thermal barriers
Heavy-duty sealing
Vibration isolation
4. Chemical Exposure
Tell us what chemicals or fluids will contact the silicone sheet.
Examples include:
Air
Oils
Cleaning agents
Chemicals
Coolants
Food products
Pharmaceutical solutions
Silicone has good resistance to many environmental conditions, but it isnot universally resistant to every chemical or fluid. Compatibility should be verified for the actual application.
5. Mechanical Requirements
For applications involving stretching, pemotongan, compression, or repeated movement, mempertimbangkan:
Tensile strength
Tear strength
Pemanjangan
Compression set
Kekerasan
Abrasion resistance
If the sheet will be used as a gasket, the required compression and sealing pressure should also be provided.
