Silicone Sheets & Rolls

Silicone sheets and rolls offer reliable sealing, cushioning, and insulation for projects that involve glass, acrylic, metals, and composites. Known for excellent thermal stability, they maintain performance across wide temperature swings, helping with heat shielding, oven doors, LED lighting, and HVAC ducting. Their resistance to UV, ozone, moisture, and many chemicals makes them a smart choice for outdoor glazing, marine environments, and cleanroom applications. Non-stick and low-taint properties support food-contact and pharmaceutical uses when a suitable grade (such as FDA-compliant or platinum-cured) is selected.

Common uses include gaskets and washers, vibration-damping pads under glass or acrylic panels, protective spacers, electrical insulation, and die-cut seals for enclosures. Rolls provide long, continuous lengths for door seals and production runs, while sheets are convenient for prototyping and small-batch fabrication. Many options are easy to cut with a knife, shears, or die, and are available with pressure-sensitive adhesive backing for quick installation.

Selection tips:
- Thickness: Choose from thin films for membrane seals to heavy gauges for gap filling and load distribution.
- Durometer (Shore A): Softer (e.g., 30–40A) for conformable sealing; medium (50–60A) for general gaskets; harder (70–80A) for higher compression and wear.
- Grade: General-purpose red oxide for elevated temperatures; translucent food/medical grades for compliance; electrically insulating for electronics.
- Structure: Solid silicone for durability; silicone sponge/foam (closed-cell) for lightweight compression sealing and thermal breaks.
- Size: Sheets for discrete parts; rolls minimize seams on long runs. Check width, length, and tolerance for your cut plan.

Performance benefits include low compression set for long-lasting seals, excellent dielectric properties, and strong weathering resistance that protects edges of glass and acrylic from abrasion and rattling. For best results, measure grooves precisely, target a slight interference fit, and allow 5–10% compression for static seals. If bonding to glass or acrylic, ensure surfaces are clean and consider primer or adhesive-backed options for a dependable, tidy installation.
