High Temperature Solid Silicone Rubber Sheets
Heat Resistant Silicone Rubber Sheet Supplier
High-temperature solid silicone sheets are used in equipment where continuous thermal exposure and sealing integrity are required. The material maintains mechanical compression force under heat, withstands thermal cycling, and resists permanent deformation, making it suitable for gasket fabrication and thermal process sealing in industrial environments.
- Continuous thermal cycles
- Mechanical compression and sealing
- Exposure to steam, oils, or food media
- Precision fit against metal or composite surfaces
- Clean processing requirements (food or medical)
The material withstands:
Continuous: 200–250 °C (392–482 °F)
Peak exposure: 300 °C (572 °F), depending on grade
Low temperature flexibility: −60 °C (−76 °F)
This performance provides sealing stability under both heat and vibration without hardening, cracking, or significant compression set.
High Temperature Silicone Sheet
High-temperature solid silicone sheets are engineered for continuous thermal exposure and mechanical sealing requirements in industrial equipment. Unlike foam or sponge silicone materials, solid silicone maintains compression strength and dimensional stability under load, making it suitable for gasket fabrication, heat press pads, equipment sealing, and thermal interface applications where both temperature and sealing integrity are critical.

---Lead Time & Minimum Order
Standard stock items have low MOQs starting from 1–2 rolls, while custom items can be negotiated according to total square meters. Typical lead time ranges from 7–15 days based on order volume and customization levels.
---Quality Assurance
Each batch undergoes hardness, thickness, and visual checks with recorded batch data for traceability. Compliance with food-contact regulations is verified through third-party laboratory testing when required by the customer.
Solid Silicone vs Alternative Elastomers
| Material | Continuous Temp | Notes |
|---|---|---|
| Silicone | 200–250°C | Best for food/pharma and low compression set |
| EPDM | 90–120°C | Good steam resistance, lower temperature capability |
| NBR | 80–100°C | Fuel and oil resistance, limited high temperature performance |
| FKM / Viton | 150–180°C | Excellent chemical resistance, higher material cost |
| PTFE | 230°C | Non-elastomeric, poor compression recovery compared to silicone |
Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone sheets in roll form are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.

Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test rolls can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.

After-Arrival Support
If any damage or discrepancies are discovered during unloading or inspection, customers may contact us within 7 days with photos and batch information. Our team will respond promptly to assess the situation and provide a reasonable solution.
Happy Customers
Year after year, multiple industries recognize Suconvey Rubber as a leader in quality, service, and innovation. We’re proud to be one of the top rubber products manufacturers in the world.
Frequently Asked Questions
