HT200 Sound Block Silicone

BISCO® HT200 Sound Block materials are specifically designed to reduce the transmission of sound within interior spaces while inhibiting the spread of fire and smoke. The elastomeric materials use filler technology to solve acoustic, fire and smoke issues within a variety of markets.

Compliant to Fire, Smoke and Toxicity standards such as EN45545-2 and BS6853, HT200 is the ideal material to reduce sound on wall panels, flooring and ducting.

Manufactured in roll form, this material is sold by weight rather than thickness and can be converted into strip or gasket shapes with or without adhesive backing.

Features and Benefits

Flame retardant

Flame retardant properties ensure compliance to international safety standards for Mass Transit.

Filler technology

Filler technology reduces the spread of flame and toxic smoke during accidents, which are a leading cause of injuries.

Sound transmission

Sound transmission can be “tuned” by adjusting the areal density or weight of the materials. (speak to a member of our team for more information).

Rubber elastomer

Rubber elastomer has good tear strength with excellent resistance to compression set, UV light, moisture, and cleaning alcohols.

Maintains properties

Maintains properties at temperatures between -67°F and 482°F (-55°C and 250°C).
