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.
Silicone foam materials, 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.)
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.
Marian has been converting Rogers materials since the 1970s. We are a long-standing Rogers Preferred Converter with access to many of their high-performance materials. Marian die-cuts thousands of custom gaskets from BISCO HT-800 for our customers every year.
