Kanecaron/Protex does not melt or drip when ignited. Instead it forms a char barrier through carbonization.

Thermoplastic fibers, such as polyester or nylon, have the potential risk of molten droplets forming which could stick to the skin and cause severe burns. FR polyester shares the same characteristics. Kanecaron/ Protex helps to reduce the risk of molten droplets when blended with thermoplastic fibers. The degree to which Kanecaron/Protex can help reduce the risk of molten droplets will depend on the blend ratio of Kanecaron/Protex used.

The Flame Retardancy of Kanecaron (BS5852:1990 source) —Upholstery

Self-extinguishes after the removal of the flame source, forming a carbonized barrier to prevent the spread of fire.

Burns and melts, followed by a flame spread through the hole and into the foam
