Product Description

-Smooth & Non-stick Surface: Uniform sleek surface ensures no sticking, no marks and no residue after hot pressing and peeling, protecting workpiece surface perfectly.

- Excellent Resilience & Stability: Fine and uniform closed-cell structure provides lasting compression recovery, not easy to deform after long-time use.

- Wide Temperature Resistance: Works stably from -60°C to 300°C, suitable for extreme cold and high-temperature industrial environments.

- Anti-aging & Weather Resistant: Strong resistance to UV, ozone and chemical corrosion, extending service life greatly.

- Safe & Eco-friendly: Made of premium silicone material, non-toxic, odorless and harmless, compliant with industrial safety standards.

- High Insulation & Cushioning: Great thermal insulation, shock absorption and sound insulation performance.

- Customizable: Custom thickness, width, length, hardness, single-sided or double-sided adhesive backing are available.

Applications

Smooth surface silicone foam rolls are widely used in industries requiring high cleanliness, high flatness and non-stick performance:

  • Heat Press Industry: Heat press cushion, thermal pressing pad, transfer printing backing pad, no-mark hot pressing lining.

  • Electronics Industry: Precision electronic shock absorption, gap filling, thermal insulation and sealing gaskets for circuit boards and electronic equipment.

  • Packaging & Sealing: High-temperature heat sealing buffer, anti-stick lining for packaging machines.

  • Food & Machinery: Food machinery anti-stick gaskets, high-temperature equipment protective lining.

  • Industrial Insulation & Sealing: Thermal insulation for industrial equipment, anti-slip and shockproof cushioning, high-temperature resistant sealing strips.

  • Automotive & New Energy: Buffer and insulation materials for new energy equipment and automotive internal accessories.
