Lifespan of polycarbonate sheet

The lifespan of polycarbonate (PC) sheets is influenced by material quality, usage environment, and maintenance, generally ranging from 10 to 20 years, with some high-quality products exceeding 20 years under ideal conditions.

Key factors affecting their lifespan include:

1. UV Protection Layer Quality:

High-quality PC sheets have a co-extruded UV-resistant coating that effectively prevents yellowing and reduced light transmittance. If the coating is missing or deteriorated, the sheet may show significant aging within 3-5 years.

2. Installation Property:

Failure to account for thermal expansion and contraction, over-tightening screws, or improper sealing can lead to stress cracking, deformation, or leakage, significantly shortening the actual lifespan.

3.Chemical Environment:

Prolonged exposure to strong solvents (such as acetone and aromatic hydrocarbons) can cause stress cracking or material degradation, affecting durability.

4.Cleaning and Maintenance:

Regularly cleaning the surface of dust and contaminants, and avoiding scratching with hard tools, helps extend the sheet’s performance stability period.
