Pioneering High-Safety Composite Material Engineering and Sustainable Architectural Cladding Solutions Worldwide
Linyi Rich New Materials Co., Ltd. stands as a premier modernized industrial and trading enterprise, seamlessly integrating advanced research & development, continuous extrusion production, and international logistics. Headquartered in Linyi City, Shandong Province—China’s epicenter for timber processing and composite material innovation—the enterprise operates an expansive, intelligent production infrastructure covering 100,000 square meters and employs over 300 highly skilled professional technicians and engineers.
As fire compliance codes become increasingly stringent across commercial, residential, and industrial construction sectors globally, traditional timber and standard WPC cladding materials no longer meet structural safety benchmarks. Responding to this global paradigm shift, Linyi Rich New Materials has focused extensive R&D resources on perfecting fire-retardant B1-grade Wood-Plastic Composites (WPC), rigid core Stone-Plastic Composites (SPC), and high-density interior acoustic paneling systems.
How Advanced Intumescent Chemistry and Polymer Synergies Eliminate Flammability Risks in Wood Composites
Upon thermal exposure, our proprietary flame-retardant additives undergo an endothermic reaction. They release non-combustible gases (water vapor and carbon dioxide) while forming a dense, carbonaceous protective char layer on the surface. This physical barrier suppresses oxygen access and cuts off heat transfer to the inner core polymer matrix.
Unlike legacy fireproofing techniques that rely on toxic halogenated compounds, Linyi Rich utilizes non-toxic Ammonium Polyphosphate (APP), Aluminum Trihydrate (ATH), and Magnesium Hydroxide (MDH). This ensures extremely low smoke density (s1 class) and zero toxic halogen gas release during fire emergencies.
Through micro-encapsulation and high-shear twin-screw extrusion, micro-refined wood fibers (30-50 mesh) are completely encapsulated by flame-inhibiting HDPE/PVC polymers. This leaves no exposed cellulose channels for flame propagation or moisture absorption.

| Limiting Oxygen Index (LOI) | < 21% | 23% - 25% | ≥ 34% (Self-Extinguishing in Air) |
Unlocking Unrivaled Manufacturing Capacities, Cost Efficiencies, and Stringent Quality Assurance
With 120 continuous WPC grating extrusion lines and 40 dedicated outdoor wall panel production lines, our manufacturing floor achieves an annual output of over 12 million square meters. We guarantee rapid turnarounds for mega-scale infrastructure projects, eliminating supply chain bottlenecks.
Situated in Shandong's primary chemical and wood processing hub, Linyi Rich maintains direct strategic alliances for eco-resin, refined wood fiber, and flame-retardant chemical supply. This vertical integration reduces raw material cost fluctuations by up to 18% compared to Western competitors.
House over 200 proprietary extrusion molds and advanced multi-axis CNC carving equipment. We allow architects and commercial developers to customize flute profiles, interlocking joinery systems, wood-grain textures, and bespoke fireproofing specs tailored to regional building codes.
Every production batch undergoes strict quality control protocols under ISO9001, ISO14001, and CE certification standards. Factory-direct testing evaluates tensile strength, thermal expansion coefficients, density, and fire reaction kinetics prior to container shipment.
Where Fire Safety Meets Architectural Aesthetics
Used extensively in luxury hotel lobbies, corporate headquarters, and high-rise interior corridors. Our B1 fire-rated fluted WPC wall panels deliver high thermal insulation and acoustic absorption while fulfilling stringent municipal fire codes for public gathering spaces.
Hospitals, universities, and public libraries require zero-formaldehyde emissions alongside class-leading fire retardancy. Our non-toxic, moisture-resistant indoor WPC wall paneling ensures hygiene, impact endurance, and fire evacuation protection.
Designed for residential and resort developments in coastal and high-temperature wildfire regions across North America, Southern Europe, and Australia. Heavy-duty co-extruded outdoor WPC cladding resists UV degradation, saltwater corrosion, and airborne spark ignition.
Subway concourses, airport terminals, and train station interior acoustic ceilings require materials that do not emit dense smoke during fires. Our acoustic wood slat panels meet strict ASTM E84 and EN 13501 standards for safe public transit environments.
