How to Properly Store PC Dual-color Tubes to Prevent Discoloration

Polycarbonate is susceptible to UV-induced yellowing if not stored properly. Recommended storage guidelines:

1. Keep Away from Sunlight
Store tubes in original packaging or cover with opaque material.

2. Temperature Control
Ideal storage temperature is 15°C — 25°C. Avoid storing near heat sources.

3. Horizontal Storage
Store tubes horizontally with support every 500mm to prevent warping.

4. Shelf Life
UV-stabilized PC tubes: 24 months. Standard grades: 12 months.

5. Cleaning
Use soft cloth with mild soapy water. Never use solvents or abrasive cleaners.
