Flame retardant filter cotton is a filter material used in spray working environments and equipment with fire resistance requirements.

　　Materials and characteristics

　　According to filtration efficiency, it can be divided into two categories: initial efficiency and medium efficiency;

　　There are two types based on flame retardancy; 1. Not flammable when exposed to open flames; When encountering an open flame, it only contracts and does not burn, which can be tested using the vertical method

　　3. A gradually dense random mesh structure made of flame-retardant fibers and special post-processing, with high dust collection rate

　　4. It combines the characteristics of other similar filter cotton
