Dressings - All Burnfree dressings are designed for first aid use on all types of burn injuries. The dressings are constructed of a special soft, open cell foam and are elastic enough to allow possible swelling or the need to flex joints. Burnfree dressings are non-adherent and the inert foam will not shed threads, strands or fibres that could get embedded in the wound. The pliable foam holds 50 times its weight in gel, meaning the gel will always stay in contact with the burn.
