Their stability, waterproof performance, durability, and aesthetic effect make them a preferred alternative to traditional wood, PVC panels, and gypsum boards.<\/p>\n\n\n\n<p>For international distributors, construction contractors, wholesalers, and project buyers, understanding <strong>what raw materials are used to produce WPC wall panels<\/strong> is crucial. Raw materials determine the panel\u2019s mechanical strength, lifespan, fire resistance, environmental performance, and overall cost.<\/p>\n\n\n\n<p>This article provides a comprehensive and deeply professional explanation of <strong>the raw materials for WPC wall panels<\/strong>, including material composition, performance roles, ratios, sourcing standards, and how different formulations influence the final product quality. As a <strong>China-based WPC wall panel manufacturer<\/strong>, we also share our internal factory insights to help you evaluate suppliers more accurately.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Introduction: Why Material Composition is Key to WPC Wall Panel Quality<\/h2>\n\n\n\n<p>WPC is a composite material combining <strong>wood fibers<\/strong> \u0648 <strong>plastic polymers<\/strong>, reinforced with <strong>stabilizers<\/strong>, <strong>colorants<\/strong>, <strong>lubricants<\/strong>\u060c \u0648 <strong>functional additives<\/strong>.<\/p>\n\n\n\n<p>The performance of WPC panels depends heavily on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The purity of raw materials<\/li>\n\n\n\n<li>The ratio of wood powder to plastic<\/li>\n\n\n\n<li>The type of plastic resin<\/li>\n\n\n\n<li>The quality of additives<\/li>\n\n\n\n<li>The production process<\/li>\n<\/ul>\n\n\n\n<p>Different factories use different grades of materials, which directly affect:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Performance Factor<\/th><th>Low-Grade

Materials of WPC Wall Panels<\/h2>\n\n\n\n<p>WPC wall panels are mainly composed of the following:<\/p>\n\n\n\n<p><strong>Wood Powder (Wood Fiber \/ Bamboo Fiber)<\/strong><\/p>\n\n\n\n<p><strong>Plastic Resin (PVC \/ PE \/ PP, most commonly PVC for indoor wall panels)<\/strong><\/p>\n\n\n\n<p><strong>Calcium Carbonate (CaCO\u2083)<\/strong><\/p>\n\n\n\n<p><strong>Stabilizers<\/strong><\/p>\n\n\n\n<p><strong>Color Masterbatch<\/strong><\/p>\n\n\n\n<p><strong>Lubricants<\/strong><\/p>\n\n\n\n<p><strong>Functional Additives (Fire retardants, UV absorbers, impact modifiers, etc.)<\/strong><\/p>\n\n\n\n<p>Below is a detailed breakdown of each raw material, its role, quality grades, and how it affects the final product.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Wood Powder: The Main Structural Component of WPC<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1.What is Wood Powder?<\/h3>\n\n\n\n<p>Wood powder (or wood fiber) comes from natural wood, bamboo, or agricultural waste such as sawdust.<\/p>\n\n\n\n<p>It is typically ground into:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>20 mesh<\/li>\n\n\n\n<li>40 mesh<\/li>\n\n\n\n<li>80 mesh<\/li>\n\n\n\n<li>100+ mesh<\/li>\n<\/ul>\n\n\n\n<p>The finer the powder, the smoother the finished surface.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.Functions of Wood Powder<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Enhances rigidity and structural strength<\/li>\n\n\n\n<li>Provides natural wood grain feel<\/li>\n\n\n\n<li>Improves panel stability<\/li>\n\n\n\n<li>Reduces shrinkage and deformation<\/li>\n\n\n\n<li>Enhances screw-holding ability (important for ceiling\/wall installations)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3.Quality Levels<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table

fiber<\/strong><br>For outdoor decking\/cladding: <strong>55%\u201370% wood fiber<\/strong><\/p>\n\n\n\n<p>As a manufacturer, we only use <strong>A-grade dried wood\/bamboo fiber<\/strong>, moisture controlled below 1.5% to ensure stable extrusion quality.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Plastic Resin: Determines Waterproof and Durability Levels<\/h2>\n\n\n\n<p>Plastic resin is the <strong>second key component<\/strong>.<\/p>\n\n\n\n<p>Common resins include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>PVC (Polyvinyl Chloride)<\/strong> \u2192 Most used for interior wall panels<\/li>\n\n\n\n<li><strong>PE (Polyethylene)<\/strong> \u2192 Mostly for decking and outdoor cladding<\/li>\n\n\n\n<li><strong>PP (Polypropylene)<\/strong> \u2192 High strength but more expensive<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">1.Why PVC is the Best for WPC Wall Panels?<\/h3>\n\n\n\n<p>PVC provides:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Excellent waterproof performance<\/li>\n\n\n\n<li>Strong flame retardancy<\/li>\n\n\n\n<li>High dimensional stability<\/li>\n\n\n\n<li>Good bonding with wood fiber<\/li>\n\n\n\n<li>High extrusion strength<\/li>\n\n\n\n<li>Long service life<\/li>\n<\/ul>\n\n\n\n<p>WPC wall panels for interior decoration are almost always <strong>PVC-based WPC<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.Types of PVC Resin<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table

option<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">3.PVC Purity Directly Affects Quality<\/h3>\n\n\n\n<p>High-purity PVC ensures:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>No odor<\/li>\n\n\n\n<li>Smooth surface<\/li>\n\n\n\n<li>Excellent waterproof performance<\/li>\n\n\n\n<li>Stable extrusion<\/li>\n<\/ul>\n\n\n\n<p>Low-quality PVC leads to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bubbles in the panel<\/li>\n\n\n\n<li>Poor density<\/li>\n\n\n\n<li>Deformation at high temperature<\/li>\n\n\n\n<li>Faster
