Description
Vulcanized fiber sheet 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.
We 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.Color: Gray, Black, Red, White, and other colors,Thickness Range: 0.010"
to 2",Standard Sheet Sizes: 48"x48" and 48"x84",Standard Roll Width: 48"
Features
Vulcanized fiber sheet offers flexibility, impact resistance, high tear strength and a smooth,
abrasion resistant surface. It can be machined, punched, slit, threaded, formed, molded
and wound into tubes for literally countless applications.
It provides excellent electrical insulation values, and is arc and track resistant. Even though
composed of cotton and wood pulp, standard VF can be used at operating temperatures of
110C-120C and has a flame resistance rating of U.L. 94HB. The use of additives and/or
coatings can provide a rating of 94VO, and laminating to polyester film will bring
the U.L. thermal rating up to 130C.
Applications
Vulcanized Fiber sheet is impervious to most organic solvents, oils, and petroleum
derivatives. This makes it an excellent choice for use in oil. Like wood, to which
it is related, VF will absorb water, but will not delaminate in its presence.
It will tend to "breath" or adjust its moisture content as the ambient moisture level
changes.
From raw materials to finished products, every process is tested and controlled professionally and seriously by our professional machines and person.
