Flame-resistant fiber Lastan™

With an advancing, diversifying and aging of society, incidences of fire and human-made disasters increase, along with growing risks of related accidents.
With the formulation of the Product Liability Act, we are required to prevent the above-mentioned risks as much as possible.

Our flame-resistant fiber Lastan™ has high resistance to heat and flame.
In the event of an accident, it won't burn.
With various postprocessing processes, Lastan™ shields heat and flame, and as the most suitable material for the fire safety related area and industrial material area, it meets social needs and receives a high evaluation.

Manufacturing process of Lastan™

Features of Lastan™ spatter sheet

• Fiber made from special acrylate fiber by carbonization-firing.
  Uses fibers which have high resistance to flame and heat.
• Higher flame resistance (LOI value) than the traditional flame-retardant fibers and heat resistant fibers.
• Even at high temperature or upon contact with flame, won't melt but will merely glow in the air.
  Excellent dimensional stability.
• Lightweight fiber with a soft texture and causes no dust problems such as those caused by asbestos.
• High resistance to flame and heat against slag and sparks during welding or fusing processes.
  Sheet which is resistant to tearing.
• JIS A 1323 compliant product

Notes

• When heated for a long time at a high temperature, oxidation degradation can occur in the same way as with glass and asbestos.
• Because fibers are fired, black fibers can come off in some product types.
• Cannot be dyed.

Limited oxygen index of Lastan™

A higher limited oxygen index (LOI) means a higher resistance to flame.
Lastan™ is an organic fiber with excellent flame resistance.

LOI
Lastan™		Carbonized while the current condition is preserved.
PBI
Novoloid		Carbonized while the current condition is preserved.
Aramid		Softening, shrinking.
Fireproof wool
Modacrylic fiber		Burning while being shrunk and fused.
Wool		Burning while being softened and sintered.
Polyester		Burning while being shrunk and fused.
Nylon		Burning while being shrunk and fused.
Rayon		Burning without softening and fusing.
Cotton		Burning without softening and fusing.

* LOI (Limited oxygen index) JIS K 7201: Minimum oxygen volume fraction required to keep burning.
