Woven and non-woven fabrics
LASTAN™️
Organic non-woven fabric with excellent flame retardancy
LASTAN™️ has higher flame retardancy than most other organic non-woven fabrics. Even in case of fire, LASTAN™️ does not easily burn and blocks heat as well as flames due to various post-processing methods applied to it. With its soft and supple texture, it is highly regarded as an optimal material that meets the needs related to disaster prevention, safety, and industrial materials.

Flame retardancy
Fabrics with an LOI (limiting oxygen index) of 26.5 or higher are said to be self-extinguishing, and fabrics with an LOI higher than the above are called flame retardant fabrics. LASTAN™️ has an LOI much higher than the standards. It is a non-flammable non-woven fabric that never burns in the air. Regarding the UL94 Standards which indicate the flame resistance of materials, LASTAN™️ has obtained the highest level, 5VA. It is the most suitable base fabric and surface material for high-performance functional materials that meet various flameproof and fire-retardant standards.
Heat resistance
LASTAN™️ is highly heat-resistant to retain its original shape without burning, melting, and shrinking even when it comes into contact with fire. LASTAN™️ has obtained a "non-combustible" certification after Material Combustion Test for Railroad Vehicles, which evaluates the non-combustibility performance of materials used for railway vehicles. Regarding measures against railway vehicle fires, a section of technical criteria related to railways which are specified in a Ministerial Ordinance issued by the Ministry of Land, Infrastructure, Transport and Tourism stipulates as follows: “The body of passenger cars shall be built with the appropriate structure and materials so that they can prevent prospective fires from starting and spreading."
LASTAN™️ is used as a heat-resistant material for railway vehicles because of its nonflammability property.
Excellent processability
Traditional inorganic fiber such as glass fiber and aramid fiber has a hard texture. On the other hand, LASTAN™️ has a very soft, supple touch and wool-like texture, while keeping excellent flame resistance. In addition, it is extremely lightweight compared to carbon fiber and inorganic fiber. With these features, LASTAN™️ is suitable for various types of post-processing such as making composites composed of LASTAN™️ and other materials.
Flame retardant insulation
LASTAN™️ contributes to a comfortable vehicle interior environment by shutting off heat radiated from the engine.
Electrical insulation
Many electric wires are used in automobiles. The wires include those for headlights, air conditioners, and computerized engines. LASTAN™️ can prevent the fire due to short-circuit of electrical wire from spreading to other parts of the vehicle.
Flameproof material around LiBs
Interest in the environmental impact of increased greenhouse gas emissions has been growing year by year, and the shift from gasoline vehicles to EV vehicles is accelerating. On the other hand, fire from EV vehicle batteries has become a problem, and automotive manufacturers are looking for measures to prevent the fire. Applying LASTAN™️ around LiBs would delay the spread of fire due to LiB thermal runaway, which ensures enough time for the passengers to evacuate from the burning vehicle.
Efforts toward the environment
RoHS Directive:(Directive on the Restriction of the use of certain Hazardous Substances in electrical equipment)
In Europe, since July 1, 2006, the RoHS Directive has been enacted to restrict the use of hazardous substances in electrical and electronic equipment. The Directive regulates the use of six harmful substances: Lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE.
The raw materials of LASTAN™️ also comply with other regulations including the REACH and the TSCA. Contact us for further information on conditions such as compliance with the latest REACH SVHC List.
REACH:Registration, Evaluation, Authorization and Restriction of Chemicals
The REACH Regulation is the comprehensive regulations of the European Parliament and the European Council on the registration, assessment, authorization, and restriction of chemicals, which entered into force on 1 June 2007.
