In public transport and in public buildings safety is one of the most important aspects. This concerns also the prevention of fire. Therefore, all the interiors have to meet a range of fire-resistance specifications.
The TFL PROTECT LINE significantly improves the already good burning behaviour of leather articles. So passengers in planes, trains, buses and cars can enjoy a safe and relaxed journey.
Leather is not a readily burnable substance. 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, which allows 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 the escape time. Hence, any increase in the escape time by using 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. A 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 a 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
Picture 1 and 2 (below, from left): The Bunsen burner is held for a defined time, typically 12 seconds or 60 seconds, under a vertical sample and then withdrawn. For a further 15 seconds the burning behaviour incl. the flaming time, glow time and burn length of the test material are measured.
Picture 3 (below, from left): The untreated leather continues to burn slowly after the flame is removed.
TFL Protect Line offers a variety of eco-friendly chemicals for the wet-end and finishing processes:
