Impact
Strength
The Impact
strength of
solid P.C. sheet is 200 times that of glass. |
Light
Weight
The weight of
solid P.C. sheet is only about half that of glass and will help in
saving of structural costs. |
Transparency
solid P.C. sheet are crystal clear and the light transmission of
clear sheets is about 88%. |
UV-protection
During
the production of
solid P.C. sheets, high density Ultra Violet ray absorbent is
co-extruded. The sheets do not decolour or yellow. |
Resistance
to Weather
solid P.C. sheet has good weather ability, it can maintain excellent
properties in wide temperature range from -40°C to + 120°C. |
Thermal
Insulation
The K-valve
of glass is 1.20 times that of
solid P.C. sheet, and hence can prevent heat loss and save more
energy. |
Flame
Resistance
solid P.C. sheet's behavior conform to the standard of difficult -
flammability material and is rated class B-1 according to QB8624-
1997. |
