Industrial Dominance & Next-Generation Composite Manufacturing Infrastructure
Linyi Rich New Materials Co., Ltd. stands as an industry-leading modernized enterprise integrating advanced R&D, high-precision extrusion manufacturing, global supply chain logistics, and architectural material consulting. Headquartered in Linyi City, Shandong Province—China’s premier logistics and wood composite hub—our state-of-the-art manufacturing campus spans over 100,000 square meters and houses an elite workforce of more than 300 senior technicians and chemical engineers. We specialize in producing engineering-grade Panel Dinding WPC (Wood Plastic Composite Wall Panels), UV Marble Sheets, SPC Flooring, Acoustic Wall Systems, and Bamboo Charcoal Veneers designed for global distribution.
Operating 120 fully automated high-speed extrusion lines yielding an annual capacity of over 12 million square meters. Engineered with flawless wood grain texturing and flame-retardant thermoplastics.
Powered by 4 high-precision rigid core extrusion systems outputting 3 million square meters annually. Features 100% waterproof stone-polymer matrices with zero formaldehyde emissions.
Equipped with 40 heavy-duty customized lines producing 2 million square meters per year. Formulated with UV stabilizers and anti-aging agents specifically for extreme climatic stress.
An in-depth technical analysis of Wood-Plastic Composite physics, molecular stability, and structural superiority.
The structural integrity of Panel Dinding WPC (Wood Plastic Composite Wall Panels) relies on a precisely calibrated balance between micro-milled wood fibers (60%), recycled/virgin thermoplastic polymers such as High-Density Polyethylene or PVC (30%), and specialized chemical processing additives (10%).
Through high-temperature twin-screw extrusion, coupling agents like Maleic Anhydride Grafted Polypropylene (MAPG) establish covalent bonds between the hydrophilic cellulose hydroxyl groups and the hydrophobic polymer resin. This eliminates interstitial micro-gaps, resulting in absolute moisture resistance, zero linear swelling, and structural rigidity superior to traditional timber.

Unlocking Supply Chain Economies of Scale, Upstream Material Synergy, and Manufacturing Efficiency.
Linyi is China's recognized wood products capital. Our direct access to micro-milled timber flour and local PVC polymer refiners drastically lowers raw material procurement costs while ensuring 100% batch consistency.
Our 120 extrusion lines are outfitted with computerized gravimetric feeders, real-time laser wall-thickness sensors, and automated inline cooling tanks, minimizing dimensional tolerance to within ±0.15mm.
Located in close proximity to Qingdao Port, Linyi Rich provides optimized container loading patterns (up to 1,800 sqm of paneling per 40ft HQ container), substantially reducing freight costs per unit.
Empowering Architectural Distributors, Wholesalers, and Commercial Contractors Worldwide.
We engineered over 200 proprietary extrusion molds, allowing enterprise buyers to specify exact profile geometry:
