Explanation of flame retardant performance of pre oxidized silk felt

The pre oxidized silk felt uses pre oxidized short fibers, which have good flame retardancy. Excellent thermal stability, with an instantaneous temperature resistance of up to 1200 ℃ and a long-term operating temperature of 400 ℃

During combustion, fibers turn red, do not melt, do not soften or contract, and do not have molten droplets, making them quasi non combustible products; The limit oxygen index of pre oxidized felt is generally around 40, and special requirements can reach around 50.

Pre oxidized silk felt can be made into a thickness of 1-10mm or higher according to customer requirements, with a weight of 80-1000 grams per square meter, which is higher. Generally divided into two styles: dense and fluffy. Dense density, large thickness, small size, high strength; The fluffy type has low density, high thickness, and high porosity. But regardless of the style, it is required to be uniform, the surface should be as delicate as possible, and the number of stitches should be reduced.
