# [Material Spotlight: BISCO HT-800 Medium Silicone Foam](https://blog.marianinc.com/blog/bisco-ht-800)

Posted by [Katie Sullivan](https://blog.marianinc.com/blog/author/katie-sullivan)

 May 27, 2020 12:02 PM

Per the Rogers Corporation Website, Rogers “*BISCO® HT-800 Medium Cellular Silicone offers the lightness of foam with the enhanced sealing capabilities of sponge rubber.*” In this post, we'll dive a little deeper into this excellent material.

[![Bisco_Logo_1000px_RGB_171026](https://blog.marianinc.com/hs-fs/hubfs/Bisco_Logo_1000px_RGB_171026.jpg?width=300&name=Bisco_Logo_1000px_RGB_171026.jpg)](https://marianinc.com/materials/bisco-silicones/)

[Silicone foam materials](https://marianinc.com/materials/bisco-silicones/), in general, are excellent materials for many reasons. Silicone elastomers will function within the largest temperature range of any elastomer. Commonly, silicones are thermally stable from -100°F to 500°F. They are highly resistant to UV. Silicone is odorless, stain-resistant, and hypoallergenic. Lastly, in terms of gaskets, compression set may be the most common cause of failure in a gasket. A silicone material, especially BISCO HT-800, will outlast all other material choices when it comes to c-set. ([Read our blog post about compression set here.](https://blog.marianinc.com/blog/compression-set))

BISCO HT-800 is an excellent material choice for gaskets that are intended for sealing and protecting outdoor enclosures that house sensitive electronic elements, including communications equipment, electronic devices, and lighting enclosures. This material is uniquely formulated by Rogers Corporation with a compact cell structure that provides enhanced sealing from moisture, fine dust particles, and fire. It also offers vibration isolation and shock absorption.

## **BISCO HT-800 Features and Benefits**

- Temperature range: -67°F to 392°F
- Available in thicknesses from 0.031 to 0.500 in.
- Typical density of 22 PCF
- CFD range of 6-14 PSI
- Rated to the most stringent flame standards.
- FDA compliant
