The Golden Formula of Basic Raw Materials
WPC wall panels are essentially a cross-disciplinary combination of wood and plastic:
Wood fiber (30-70%): Typically made from renewable resources such as wood flour, bamboo flour, or rice husks, providing natural texture and rigid support.
Thermoplastic plastics (20-50%): Using recycled plastics such as PE, PP, or PVC as the matrix, imparting waterproof and corrosion-resistant properties.
Coupling agent: Builds molecular bridges at the wood-plastic interface, solving the compatibility problem between natural and synthetic materials.
IThe Secret Weapon for Enhanced Performance
These trace additives make the wall panels more durable:
Foaming agent: Forms a microporous structure, reducing weight while improving thermal insulation performance.
Antioxidant: Resists UV degradation, preventing fading during outdoor use.
Lubricant: Improves processing flow, resulting in a smoother and more delicate surface.
Flame retardant: Enhances the material's fire resistance rating, increasing safety during use.
Intelligent Layered Structural Design
Modern WPC wall panels often employ a sandwich structure:
Top layer: High-density wear-resistant layer, scratch-resistant and easy to clean.
Core layer: Foamed composite layer, balancing lightweight, thermal insulation, and sound insulation.
Bottom layer: Moisture-proof balancing layer, counteracting deformation stress caused by temperature and humidity.
