There are strict regulations regarding the fire safety of rail vehicles in most countries of the world. A large number of passengers in a confined space with limited escape possibilities, such as in a tunnel, require special material properties.
In addition to the flammability of materials, fire side effects such as smoke density and smoke toxicity must also be taken into account. These strict requirements massively limit the product selection.
In particular, the halogen-free phosphorus-based products of the Disflamoll® and Reofos® series help to meet the requirements placed on rubber and plastic parts for rail vehicles. Levagard® products can be used in a variety of PUR-based materials such as cushions and coatings.
