Flexible Fabricated Products
High-Temperature Resistant Sealing Gaskets
Code prefix SGK
High-temperature resistant gaskets, fire-resistant gaskets, sealing gaskets and irregular-shaped gaskets are cut and formed from various high-temperature resistant fabrics and papers, in the specifications and shapes required. Common base materials include fiberglass cloth, ceramic fiber cloth, bio-soluble fiber cloth, ceramic fiber paper and ceramic fiber blanket, as well as coated fabrics such as silicone-coated, vermiculite-coated, acrylic-coated and graphite-coated cloth. Composite fabrication with several base materials is supported, and steel wire mesh or aluminium mesh can be combined into the gasket. Overall dimensions, material combinations and structural style are customised to the customer's requirement.

01 — Product description
Cut from the material the joint needs
High-temperature resistant gaskets, fire-resistant gaskets, sealing gaskets and irregular-shaped gaskets are cut and formed from various high-temperature resistant fabrics and papers, in the specifications and shapes required. Common base materials are fiberglass cloth, ceramic fiber cloth, bio-soluble fiber cloth, ceramic fiber paper and ceramic fiber blanket, together with coated fabrics such as silicone-coated, vermiculite-coated, acrylic-coated and graphite-coated cloth.
Composite fabrication with several base materials is supported, and steel wire mesh or aluminium mesh can be combined into the gasket. Overall dimensions, material combinations and structural style are customised to the customer's requirement.
Working condition suitability and restrictions
Gaskets made from different base materials differ in temperature resistance, corrosion resistance, insulation and protection. Selection follows the site working condition, temperature, medium and pressure. Gaskets suit dry static sealing, thermal insulation and fire protection, and are not suitable for strong acid or alkali corrosion, long-term liquid immersion, high-speed medium erosion or high-frequency severe friction.
Usage precautions
- Cutting and processing fiber-based gaskets releases dust; ventilate, wear dust-proof protection and dispose of waste under local environmental regulations.
- Composite metal mesh gaskets must suit the installation to avoid conductive and electrochemical corrosion between the metal and the equipment.
- Test suitability against the actual temperature, pressure and medium before use; over-condition use is prohibited.
- All technical data are for reference; users should test suitability and follow relevant safety regulations.

Service limits
- Base materials differ in temperature resistance, corrosion resistance and insulation; select against the site temperature, medium and pressure.
- For dry static sealing, insulation and fire protection: not for strong acid or alkali, long-term immersion, high-speed media erosion or high-frequency severe friction.
- Composite metal mesh gaskets must suit the installation to avoid conductive and electrochemical corrosion between the metal and the equipment.
- Cutting releases fiber dust; ventilate, wear dust protection and dispose of waste under local environmental regulations.
