Silicone Gasket Sheet

ElastaPro is a U.S. manufacturer that produces silicone gasket sheet in a range of durometers, densities, grades, and thicknesses.

Solid Silicone Gasket Sheet

ElastaPro’s solid silicone sheet is available in durometers from 20 to 90 Shore A so that engineers can match hardness (durometer) to sealing force, compression requirements, and mechanical loading conditions.

Key Engineering Attributes

High temperature stability
Suitable for continuous exposure to elevated temperatures without embrittlement or compression set.
Wide range of specialty grades
ElastaPro offers commercial, general‑purpose, FDA‑compliant, fuel‑ and solvent‑resistant, electrically conductive, fiberglass‑reinforced, medical, high‑strength, extreme flame‑retardant, extreme high‑temperature, extreme low‑temperature, and metal‑detectable formulations.
Precision fabrication
Solid sheets support die‑cutting, water‑jet cutting, and CNC conversion for tight‑tolerance gasket geometries.

Applications

Solid silicone gasket sheets are ideal for static and dynamic seals, high‑temperature enclosures, medical devices, food‑contact equipment, and electronics requiring dielectric insulation.

Foam Silicone Gasket Sheet

Foam silicone sheet is engineered for applications requiring low compression force, lightweight sealing, and excellent thermal stability. It has a consistent cell structure and combines environmental durability with compatibility with precision fabrication.

Key Engineering Attributes

Low‑density structure for compressible, conformable sealing
Thermal and UV resistance suitable for outdoor and high‑temperature environments
Vibration damping for electronics, aerospace, and automotive assemblies
Low compression set for long‑term sealing reliability

Applications

Foam silicone gasket sheets are used in HVAC systems, lighting enclosures, battery packs, aerospace panels, and applications requiring EMI shielding when paired with conductive foams.

Sponge Silicone Gasket Sheet

ElastaPro’s sponge silicone sheet is a closed‑cell material designed for gasketing applications requiring environmental sealing, water resistance, and medium‑density compression. Their sponge sheets are available in continuous rolls up to ½ inch thick and sheets up to 2 inches thick, with a fine fabric‑finish surface for consistent sealing performance.

Key Engineering Attributes

Closed‑cell structure prevents water absorption and wicking
Medium‑density formulation balances compressibility and mechanical strength
Excellent environmental durability including ozone, UV, and temperature resistance
Available in thick sections for large‑gap sealing or cushioning applications

Applications

Sponge silicone is ideal for outdoor enclosures, NEMA/IP‑rated seals, transportation equipment, HVAC systems, and vibration‑isolating pads.
