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
