Rexalon Polycarbonate Sheet

Impact Strength

The Impact strength of Rexalon solid P.C. sheet is 200 times that of glass.

Light Weight

The weight of Rexalon solid P.C. sheet is only about half that of glass and will help in saving of structural costs.

Transparency

Rexalon solid P.C. sheet are crystal clear and the light transmission of clear sheets is about 88%.

UV Protection :

During the production of Rexalon solid P.C. sheets, high density Ultra Violet ray absorbent is co-extruded. The sheets do not decolour or yellow.

Resistance to Weather :

Rexalonsolid 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 Rexalon solid P.C. sheet, and hence can prevent heat loss and save more energy.

Flame Resistance :

Rexalon solid P.C. sheet's behavior conform to the standard of difficult - flammability material and is rated class B-1 according to QB8624- 1997.
