POLYBETT® EXTERIOR HPL WALL PANEL

Exterior HPL Wall Panel Structure

Exterior-HPL-Panels-structure

1. Layer Structure Interpretation (As Shown in Drawing)

·UV Protection Film (Top & Bottom)

Outer weather-resistant coating that blocks UVA/UVB rays, prevents surface fading and chalking under long-term sunlight exposure.

·Decorative Paper (Dual Sides)

Impregnated melamine decorative layer, providing rich solid color, wood grain or stone textures, scratch-resistant and easy to wipe graffiti.

·Multiple Layers of Kraft Paper Core

Dense phenolic resin-impregnated kraft paper stacked and high-pressure integrated into a solid homogeneous core, zero water absorption, anti-mildew, salt-fog resistant and dimensionally stable.
 

2. Core Advantages

·Symmetrical double-sided UV balance structure avoids panel warping under temperature fluctuation
·Full solid phenolic core, no swelling or delamination in coastal/high-humidity outdoor environments
·B1 flame retardant, impact-resistant, low long-term maintenance cost
