Fire resistance

Noncombustible A   level

C   ~ D flammable, plus flame retardants into class B flame retarga

Noncombustible A   level

Smoke toxicity

Inorganic   flame retardant materials, non-toxic

The   combustion release toxic gas

Inorganic   flame retardant materials, non-toxic

Skin irritation

Fine   fibers, no shot, Fine fibers, no shot, no stimulation of the skin

No   stimulation of the skin

The   fiber coarse cause itching, slag ball lead thorny affect construction

Hydrophobicity

Hydrophobicity

Hydrophobicity

No   hydrophobicity

Tensile properties (Tensile properties)

150~200mm,   fiber grows insulation tensile higher performance, better seismic performance

Tensile   strength of small, fragile

≤40mm,tensile strength of   small, fragile

Life

No   pulverization phenomenon, can use for a long time

Long   time exposure on the outside will turn yellow, brittle

Natural   powdering the life time is greatly shortened, after a period of time after   the appearance of slag ball down, cotton body hanging elongated, and even   rupture
