Multi Wall Polycarbonate Sheet

twin wall polycarbonate sheet


Description

Excelite multi wall polycarbonate sheet has the fearures of stable structure,high stength.It is a type of engineering plastic of excellent integration capability,ideal material for roofing panel,It can support greater purlin spacing,the maximum reducation of profiles,allowing the designer to have more space to play in the selection.At the same time,the diagonal support increased lateral stability of the multi wall polycarbonate sheet has played a positive role in making the sheet's overall structure more reasonable.multi-layerstructure formed cavity to increase the thermal insulation performance,compared with the same thickness of ordinary sheet with a lower U value.

Multi wall polycarbonate sheet has lots of advantages such as highimpact,good heat-retaining properties,high security,and excellent sound insulation.
