TOYO Vulcanized Fibre

TOYO Vulcanized Fibre from Japan 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 specialtygrades to comply any application required by users, such as water resistant grades, flame retardant grades, combination grades etc. in roll, sheet and coil. Main Types: HB-77 : This fibre uses original cotton fibre sheets as its raw material. The available colors are red, white, gray and black. It is the general used fibre which can be used for motors, speakers and other electrical appliances. NF-77 : NF-77 is a UL listed flame retardant vulcanized fibre with good tracking rate, high ampere-arc, and hot wire ignition rate. It has almost the same workability as the standard grade, but can be easily flexed if slightly pre-heated. K-57 : K-57 is listed in Class E of Japan Electricity Regulation. It has an ideal incorporation of good workability of fibre and dimensional stability.

MIKI Insulation Papers
