ht-6360 rolls material
It is often known that a lot of the silicone foams, and silicone sponges that NEDC converts into gaskets are flame retardant. Recently, we did a blog on flame retardant silicone foam/sponge materials. Most gasketing materials are decently fire retardant- however the certifying to it is another discussion. However, it is not uncommon for people to begin to look for solid silicone rubber that is also flame retardant and certified to UL 94 V0.
Use of Flame Resistant/Retardant Silicone Rubber Gaskets
Out of all the silicone rubber gasketing that NEDC converts flame retardant silicone rubbers are among the most unique. The interesting thing about is that it has all the properties of typical gasketing materials while also having the extremely unique flame retardancy that is not common when it comes to silicone rubber gaskets. When it comes to solid rubber gasketing- there are not many materials available at all that meet UL 94 V0, nevermind silicone rubber materials. The two highlighted gasketing materials listed below are available in 65A, or 55A. Flame Retardancy is a common requirement across consumer electronics, but even more importantly rail, and aerospace transportation. Having firesafe transportation is critical to ensuring safety across applications. These materials are designed to protect sensitive equipment from flame damage. As expected, these type silicone rubber materials come with a wide temperature range (-80°F to 425°F). In addition, they meet FAR requirements.
