Leather is not a substance that burns readily. However, to provide a better margin of safety to allow time for evacuation of vehicles or buildings, additional fire-resistant protection is necessary. Retardants prevent fires from starting or spreading by making the material more difficult to ignite and significantly reducing the spread of the flame, providing more time for passengers and public to escape.With the increasing use of combustible synthetic materials for furnishings, as well as wall and floor coverings, there has been a noticeable reduction in escape time. Hence, any increase in t escape time through the use of non-combustible materials is a major advantage.
Leather does not melt or form flaming drips during fires. However, the strict safety regulations for public transport and buildings, where the safety and protection of human lives are the key issue, mean that additional flame retarding properties are required.
The thinner the leather the more important the fire-resistance treatments are. Thorough penetration of the fire-resistance is essential to avoid having a layer directly under the finish coat that is not protected. The untreated layer was found to be effectively feeding the burning. With the correct selection of fire-resistant chemicals that are fixed in the leather cross-selection, the possible build up of gas under the finish coat is eliminated and leads to much improved fire-resistance performance.
>> Benefits at a glance:
- Highly effective protection against, and prevention of, fire
- No formation of toxic gases when exposed to fire
- Single or combination application depending on the desired protective effect
- Flexible in all applications
- Eco-friendly
