FRP sheet is made of thermosetting fiberglass and reinforced
plastic. As a composite material, it is optically nonuniform.
Working long in the factory covered by FRP sheets won’t make the
workers feel tired. It is also energy-saving. Moreover, the
Anti-ultraviolet film covered on the surface can greatly extend
the service life of the sheets.
Normally, the
oxidation number of an FRP sheet is no more than *1%, which means
it is deflagrable. It burns itself when facing any flame, and the
higher the temperature the easier the burning will be. Once in a
fire accident, FRP sheet will burn up fast enough to make
oxygenexhaust. FRP sheet is
thermosetting, so there will no drops when it is burning. When
oxidation number is equal or higher than *8%, the sheet will be
flame resistant and self-extinguishing once away from fire. When
facing flames, high temperature, or pyrolysis, it will get into
sustained combustion.
Like other lighting sheets, the intensity of FRP will decline as
the temperature rises. When the temperature rises to a specific
value, its intensity will decline sharply. It is unlikely to age,
yellow, break or soften when the temperature varies from *0℃ to
*5℃. FRP can resist low temperatures while some other materials
can not. When the temperature drops to **0℃, its intensity tends
to rise if the temperature continues to decline.
