1,Installation & Maintenance Best Practices

Installation Tips

• UV Layer Orientation: For outdoor use, always install the sheet with the UV-coated side facing the sun (manufacturers typically mark this side with a sticker or laser print).
• Fastening: Use stainless steel or aluminum fasteners with EPDM rubber washers to prevent water ingress and avoid direct contact between metal and PC (which can cause chemical corrosion). Pre-drill holes 2–3mm larger than the fastener diameter to accommodate thermal expansion (PC expands ~0.12mm per meter per °C).
• Sealing: Use PC-compatible silicone sealant at joints and edges to create a weathertight seal.

Maintenance Guidelines

• Cleaning: Wipe with a soft cloth or sponge and mild detergent (e.g., dish soap) mixed with warm water. Avoid abrasive cleaners (e.g., scouring pads) or solvents (e.g., alcohol, ammonia), which can scratch the surface or damage the UV layer.
• Inspection: For outdoor sheets, inspect annually for signs of UV damage (yellowing, surface crazing) or loose fasteners. Replace damaged sheets promptly to prevent water infiltration.
• Storage: Store unused sheets flat in a cool, dry, shaded area—avoid stacking heavy objects on top (to prevent warping) and keep them away from direct sunlight (to protect uncoated surfaces).

2, Customization Options

• Thickness: 1mm–20mm (common options: 3mm, 5mm, 8mm for most applications; 10mm+ for heavy-duty uses like machine guards).
• Colors: Clear (standard), tinted (e.g., bronze, grey, blue for heat reduction), opaque (e.g., white, black for privacy or signage).
• Coatings: UV protection, anti-scratch (hard coating for high-traffic areas), anti-fog (for humid environments like showers), anti-glare (for displays).
• Size: Standard widths up to 2.1m; lengths can be customized (up to 10m for continuous extrusion) to reduce joint gaps.
