How to Identify The Quality Of Polycarbonate sheet?

To identify the quality of a polycarbonate sheet, you can consider the following factors:

Price: While comparing quotations from different suppliers, if there is a significant price difference for the same specifications of polycarbonate sheet, it may indicate a difference in quality. However, keep in mind that the lowest price does not always guarantee the best quality.

Transparency: High-quality polycarbonate sheets made from 100% virgin raw material should have a transparency level of more than 92%. Look for sheets that have no visible impurities, pockmarks, or yellowing. Recycled or mixed material sheets may appear yellow or dark.

 

 

 

PE Protection Film: Check if the PE protection film is firmly attached to the surface of the polycarbonate sheet without falling off. This indicates better production equipment, technology, and quality control.

Wall Thickness and Gravity: Some manufacturers may produce polycarbonate sheets with lower gravity to offer a better price. However, this can result in thinner walls compared to standard or over-standard gravity sheets. By comparing the unit gravity and wall thickness, you can distinguish the quality of the sheet. Higher unit gravity and wall thickness generally indicate better quality.

Bending Performance: High-quality polycarbonate sheets made from virgin material should have outstanding bending strength. They should be able to withstand repeated bending without easily breaking. Poor quality sheets made from recycled or mixed material may be brittle and break easily.

Flatness: Tear off the PE protection film and examine the surface of the polycarbonate sheet. A high-quality sheet should have a flat and smooth surface without any potholes, scratches, or wavy lines. Poor quality sheets may have surface imperfections.

By considering these factors, you can make a more informed decision when purchasing polycarbonate sheets and ensure that you are getting a product of good quality.
