An Excellent Insulation Material for a Variety of Applications

BISCO HT-820 is a firm silicone foam that provides excellent thermal insulation and vibration dampening properties. With its unique characteristics, HT-820 has become a popular choice for a variety of insulation applications.

Key Features of BISCO HT-820

• High thermal resistance – HT-820 has a thermal conductivity of just 0.27 W/m-K, allowing it to effectively insulate against heat transfer.
• Low moisture absorption – The closed cell structure resists moisture ingress, retaining insulation performance.
• Excellent dimensional stability – There is minimal shrinkage due to the firm foam structure.
• Vibration dampening – The foam helps absorb vibrational energy.
• Wide service temperature range – Can be used from -115°C up to +260°C.
• UL 94 V-0 rated – Meets flammability standards for electrical devices.

Typical Applications

• Appliance insulation
• HVAC systems
• Automotive heat shields
• Pipe and duct insulation
• Financial Equipment

The firm foam structure and high density make HT-820 suitable for these applications where dimensional stability and robustness is required. The table below summarizes some key properties:

Answering Common Questions

Here are answers to some frequently asked questions about BISCO HT-820 foam:

What are the standard sheet sizes available?

HT-820 is available in sheet sizes of 48 x 96 inches and 48 x 48 inches in thickness ranging from 0.5 inch to 2 inches. Custom sizes can be produced on request.

Does it require any special protection or cladding?

No, HT-820 does not require any additional cladding or protection for most applications. The foam itself has a UL 94 V-0 rating.

What are the typical applications for this foam?

Typical applications include appliance insulation, HVAC systems, automotive heat shields, pipe and duct insulation. The high density foam is suitable where dimensional stability is important.

What is the recommended operating temperature range?

HT-820 can be used in operating temperatures from -115°C up to +260°C for short excursions. The maximum continuous use temperature is 200°C.

Is HT-820 foam glueable or laminable?

Yes, HT-820 can be laminated or bonded to other materials using adhesives or contact cement. The foam surface needs to be properly prepared and cleaned prior to gluing.
