Typical Properties of Medium Density Fiberglass Reinforced Flame Retardant Closed Cell Silicone Sponge
Description: Medium density fiberglass reinforced flame retardant closed cell silicone sponge material designed for use in gaskets applications that require a soft compressible material. This material is UV and ozone resistant and takes a low compression set. In addition to having a high tensile strength, medium density fiberglass reinforced flame retardant closed cell silicone sponge offers resistance to low and high temperatures and provides users with a service temperature of -103°F to +450°F. A flame retardant and highly compressible material, the fiberglass gives this silicone sponge material dimensional stability, which is useful when cutting close tolerance parts.
M&P Sealing’s closed cell silicone sponge gasket material is available in a wide range of densities from soft to extra-firm with varying densities and formulations available in between. Medium density fiberglass reinforced flame retardant silicone closed cell sponge can be converted into rolls ranging from 1/4″ wide up to 36″ in width. Available in dark blue (standard) or grey in color, the surface has a fine fabric finish on both sides and can be manufactured in rolls or sheets with a thickness range from as thin as 1/32″, to as thick as 1/2″. M&P Sealing has the ability to supply medium density fiberglass reinforced flame retardant closed cell silicone sponge without adhesive or choose from either our standard acrylic adhesive or our high-temperature acrylic adhesive. M&P Sealing has the capacity to die-cut or waterjet cut medium density fiberglass reinforced flame retardant silicone closed cell sponge to meet your exact prototype and production requirements.
