Flame Retardants

Flame retardants and flame retardant plasticisers play an important role in the safety of products in various industries. Flame retardants are used to protect materials such as plastics and textiles from fire and to slow down the spread of fire. Flame retardant additives work by interrupting the spread of fire by forming an insulating burnt layer.

Flame retardants in the polymer industry are of crucial importance. Flame retardant additives can improve the flame retardant properties of polymers such as PVC, polyurethane and polyester without compromising their structural integrity. This is particularly important in applications such as construction, electronics and the automotive industry, where materials must meet certain fire safety standards.
