Every Silicore^® Padding Product is made with Silicore^® Fibers, unique siliconized hollow core shafts that don’t mat down, retain their loft and allow air flow. The silicone coating lubricates each fiber to reduce friction and shear force while preventing moisture penetration or retention. The breathable cotton/polyester fabric is fully washable, dryable, and radio-translucent. Silicore^® Padding Products pass the requirements described in 16 CFR Part 1632 Standard for the Flammability of Mattresses and Mattress Pads, (FF-72, Amended). Bed, Full Wheelchair and Chair Pads are also reversible with a moisture resistant nylon on the other side.
