BELLOFOAM™ 7829 vs. BISCO® HT-800 | UL 94 V-0 Fire Retardant Silicone Comparison

BELLOFOAM™ 7829 vs. BISCO® HT-800

Comparing UL 94 V-0 Fire Retardant Silicone Sponge Materials

When evaluating UL 94 V-0 rated silicone sponge materials, two names often come up: BELLOFOAM™ 7829 from Bellofram Elastomers and BISCO® HT-800 (also referred to as Rogers HT-800) from Rogers Corporation.

Both materials are designed for demanding applications that require:

• Flame resistance
• Reliable sealing
• Long-term durability
• Thermal stability

This article compares BELLOFOAM™ 7829 UL 94 V-0 silicone sponge and BISCO HT-800 fire resistant silicone foam to help engineers, purchasing teams, and OEMs determine the right solution for their application.

What Is BELLOFOAM™ 7829?

BELLOFOAM™ 7829 is a closed-cell silicone sponge sheet material engineered for sealing and cushioning applications that require:

• UL 94 V-0 flame retardancy
• Excellent compression set resistance
• Low stress relaxation
• Strong UV and ozone resistance
• Long service life in harsh environments

It is commonly used in:

• Electrical enclosures
• LED gasketing
• Transportation systems
• Industrial equipment
• HVAC systems
• Battery and energy storage applications

BELLOFOAM™ 7829 is a fire retardant foam solution manufactured in the USA and available with value-added services such as adhesive backing and flash cut parts.

What Is BISCO® HT-800 (Rogers HT-800)?

BISCO® HT-800, manufactured by Rogers Corporation (as known as Rogers HT-800), is a medium-firm silicone sponge material known for:

• UL 94 V-0 flame resistance
• Consistent compression properties
• Environmental durability
• Electrical insulation performance

HT-800 is widely used in applications requiring fire resistant silicone foam with reliable sealing performance in elevated temperature environments.

Does BELLOFOAM™ 7829 Meet UL 94 V-0?

Yes. BELLOFOAM™ 7829 is UL 94 V-0 rated, meaning:

• Flame extinguishes within 10 seconds
• No flaming drips
• Meets stringent vertical burn test criteria

For OEMs requiring fire retardant foam or fire resistant silicone for their applications, this rating is critical for safety compliance.

How Does BELLOFOAM™ 7829 Compare to Rogers HT-800?

While both materials offer UL 94 V-0 flame resistance and durable sealing performance, key differentiators of BELLOFOAM™ 7829 include:

1. Thickness Availability

• Available in thicknesses up to 2 inches without lamination
• Still typically lighter in weight than HT-800

2. Low Minimum Order Quantities

• Order as little as one sheet
• Suitable for prototyping and small production runs

3. Value-Added Capabilities

• Adhesive backing options
• Flash cut custom gaskets

4. U.S.-Based Manufacturing

• Manufactured domestically
• Reduced lead times
• Responsive technical support

For customers seeking an alternative to BISCO HT-800 or Rogers HT-800, BELLOFOAM™ 7829 offers similar performance with added flexibility in ordering, specs, and fabrication.

When Should You Choose Fire Resistant Silicone Foam?

Applications that typically require UL 94 V-0 fire retardant foam include:

• Electrical enclosures
• Power distribution equipment
• Battery systems
• Rail and transportation components
• LED lighting assemblies
• Industrial control panels

In these environments, fire resistant silicone sponge helps:

• Limit flame spread
• Improve safety compliance
• Maintain seal integrity under thermal stress
• Extend equipment lifespan

Frequently Asked Questions

Is BELLOFOAM™ 7829 equivalent to BISCO HT-800? BELLOFOAM™ 7829 offers comparable performance characteristics to BISCO HT-800 in terms of flame retardancy, compression performance, and environmental durability, while also providing greater thicknesses, flexible order quantities, and fabrication options.

Is Rogers HT-800 UL 94 V-0 rated? Yes, Rogers HT-800 is UL 94 V-0 rated. BELLOFOAM™ 7829 carries the same flame retardant classification.

What is the difference between fire resistant silicone and fire retardant foam? Fire resistant silicone refers broadly to silicone materials that resist ignition and flame spread. Fire retardant foam typically refers to materials that meet standardized flame ratings such as UL 94 V-0.

Choosing the Right UL 94 V-0 Silicone Sponge

Both BELLOFOAM™ 7829 and BISCO® HT-800 (Rogers HT-800) are proven performers in high-temperature, flame-sensitive environments.

However, if your project requires:

• Greater thickness availability
• Low minimum order quantities
• Custom fabrication
• Domestic support

BELLOFOAM™ 7829 delivers performance with added flexibility.
