SILICONE SPONGE SHEET

We supply several grades of silicone sponge sheet. Each grade comes with its own unique specifications specifically designed for high performance.

The heat resistant silicone sponge we offer is considered closed cell which means the cells are non-interconnecting. The complete enclosure of each cell means our sponge sheets are ideal for applications where mechanical properties (elasticity, tensile strength, elongation, hardness and fatigue limit) are important.

At the moment we offer 3 standard commercial grades; soft (3-8 psi), medium (6-14 psi) and firm (12-20 psi), as well as specialty grades such as blue/grey flame retardant UL 94 HB sponge. All materials are come in a wide range of thicknesses, are flexible, compressible, and offer non-stick characteristics.

SILICONE SPONGE BENEFITS

Closed cell silicone sponge sheet offer customers a highly versatile material that is easy to convert or fabricate. It is also bacteria and mildew resistant with good thermal stability. As such, it is often the rubber of choice for gaskets and seals in applications where dust and water need to be kept out. In addition, to the qualities above silicone sponge is also:

• Food Safe - through raw materials and proper processing closed cell silicone sponge can be FDA approved.
• Low Compression Set - great ability to rebound to its original thickness, this trait makes it well suited for application under compressive load.
• Ozone & UV Resistant - very good weathering properties makes it an ideal choice for outdoor applications.
• Temperature Resistant - excellent material for extreme hot or cold applications.
• Water & Moisture Resistant - a closed cell structure means low water absorption and can be used in applications where minimal water entry is essential.

SILICONE SPONGE APPLICATIONS

Closed cell silicone sponge can be converted or fabricated into many products. These end uses typically require materials that are quality consistent, dependable and can deliver outstanding performance while meeting critical safety standards in harsh working environments. For silicone sponge sheets, such as ours, potential end uses can include:

• Automotive - seals & vibration damping pads
• Construction - gaskets, seals & vibration damping pads
• Food & Beverage - gasket & seals
• HVAC - gaskets, insulation, seals & vibration damping pads
• Led Lighting - gaskets, strips, seals & vibration damping pads
• Mass Transit - insulation & vibration damping pads
• Oil & Gas - gaskets, insulation & seals
