Vulcanized fiber sheet (FLAME RETARDANT /HEAT RESISTANCE /WATER RESISTANCE ) Vulcanized fiber sheet (FLAME RETARDANT /HEAT RESISTANCE WATER RESISTANCE
Flame Retardant: YMVF-77

U.L. Listed 94 V-O

Thickness: .010”-.062”

Hot Wire Ignition: 300 sec. Min.

Heat Deflection: 120C

Flexibility: Good		 Vulcanized fibre is a material manufactured by gelatinizing several plies of high purity cellulose papers. It has extremely high internal bond strength, and mechanically excellent punching, forming, machining and many other unique properties. TOYO proudly carries specialty grades to comply any application required by users, such as water resistant grades, flame retardant grades, combination grades etc. in roll, sheet and coil

Heat Tolerance:
40,000 hrs.: 120C
(JIS K6911) 200C

Flame Listing 94 HB

Thickness: .020”-.100”

Water absorption: < 10%

Moisture is to fibre what heat is to metal. Normal moisture content (at typical ambient temperature/humidity ranges) is 5%-8%. This amount of moisture in fibre contributes to its resilience, punching and forming capabilities. Water softens or plasticizes it. In use, moisture can cause dimensional changes and should be protected against via a coating. Again, most of these effects can be minimized or eliminated through proper application selection and a quick water resistant coating.
