Exciting news! Brand Felt Group is now an official Major Converter for Rogers Corporation. This gives our customers direct access to the full BISCO® cellular silicone line. We convert it in-house to your specs.
What Are Cellular Silicones?
Cellular silicones are silicone foams with a uniform cell structure. They compress under load and recover when released. They resist compression sets, even at high temperatures. This lets them hold a seal for a long time.
They also conform well to uneven surfaces. Rogers' BISCO® line covers a wide range of compression force. Grades run from ultra-soft BF-2000 to extra-firm HT-840. All BISCO® cellular silicones are rated UL94 V-0 and HF1 for flame resistance.
What is BISCO HT-800 Foam?
HT-800 is Rogers' medium-firm cellular silicone. It has excellent memory and low stress relaxation. It springs back after compression and holds its seal over time.
Key properties:
- Typical density of 22 PCF.
- Compression force deflection (CFD) of 6–14 PSI.
- Compact cell structure that blocks fine particles and wind-driven rain.
- Available in black and gray.
Built for Lighting
HT-800 is a strong fit for outdoor lighting and electronics enclosures. Here is why:
- Flame retardant: It adds a layer of fire safety inside the fixture.
- Electrically insulating: It keeps current where it belongs.
- Very low thermal conductivity: It limits heat transfer between parts.
- UV resistant: It stands up to years of direct sun.
- Tested: It passes the standard ASTM test battery required by the lighting industry.
Outdoor fixtures are often designed and tested for a 20-year service life. The gasket should last just as long. Neoprene dries out in the sun. Over time it cracks and leaks. HT-800 holds its properties for the life of the fixture.
What The HT-800 Does in a Lighting Fixture?
- Seals: It acts as a gasket around the electronics compartment. Water stays out.
- Spaces: It sits between metal parts. This stops friction and rattling.
- Shields: It protects components from the heat of the light itself.
Converted to Your Spec
We supply HT-800 as full rolls, stripping, and die-cut parts. Thicknesses run from 1/32" to 1/2". It is available plain or with adhesive backing. See HT-800 product details and the technical datasheet.
Need a Different Firmness?
HT-800 is one of several densities in the BISCO® line. Softer and firmer grades are also available. Browse the full BISCO® range, or contact our team to find the right fit.
