Global Manufacturing Powerhouse & Intelligent Production Hub for Next-Generation Polymer Composites.
Understanding the transition from traditional timber and masonry to advanced PVC and Wood-Plastic Composites (WPC).
The global architectural and building materials sector is undergoing an unprecedented structural transition driven by global ESG (Environmental, Social, and Governance) mandates, deforestation restrictions, and the demand for zero-lifecycle maintenance materials. Traditional natural timber, while aesthetically pleasing, suffers from inherent physical degradation: dimensional instability under hydrothermal stress, susceptibility to fungal decay (basidiomycetes), termite infestations, and high carbon emissions associated with frequent chemical sealing and painting.
Custom PVC (Polyvinyl Chloride) and WPC (Wood-Plastic Composite) formulations developed by Linyi Rich New Materials Co., Ltd. bridge the mechanical gap between organic wood aesthetics and inorganic polymer durability. By micro-encapsulating refined hardwood cellulose fiber matrixes (wood flour) within virgin or recycled polyolefin thermoplastics (polyethylene, polypropylene, or rigid PVC), our co-extrusion technology creates a synergistic composite material that neutralizes water absorption while providing high flexural modulus and structural integrity.
Information Gain Insight: Unlike standard PVC profiles, enterprise-grade WPC extruded at Linyi Rich incorporates nano-particle calcium carbonate (CaCO3) reinforcement, thermal stabilizers, UV absorbers (HALS), and coupling agents (maleic anhydride grafted polyolefins). This chemical configuration minimizes the linear thermal expansion coefficient (CLTE) to under 3.5 × 10^-5 /°C, ensuring stability even under extreme diurnal temperature swings from -40°C to +85°C.

Leveraging the Linyi Industrial Cluster for Unrivaled Scale, Cost-Performance Ratios, and Speed-to-Market.
Located in Linyi, Shandong—the wood processing capital of China—our factory accesses high-purity wood flour and PVC resins locally. This eliminates multi-tier intermediate transport costs and stabilizes raw material pricing.
With 120 automated WPC grating lines, 40 outdoor panel lines, and 12 UV panel workshops, we produce over 25 million square meters annually. We absorb supply surges effortlessly without compromising delivery timelines.
Equipped with over 200 custom extrusion dies and automated multi-axis CNC engraving stations. We support OEM/ODM projects requiring tailored profile geometries, custom fluting, embossing, and precise grooving.
Engineered for commercial interiors, hospitality facades, residential decking, and specialized acoustic environments.
Our indoor WPC wall panels and grating profiles represent an advanced acoustic and decorative wall cladding system. Utilizing high-frequency extrusion technology, these hollow-core and fluted designs act as sound diffusers while offering resistance to humidity and moisture. They are ideal for high-traffic hotel lobbies, office receptions, and residential feature walls. The integrated tongue-and-groove system allows rapid installation over sub-frames, cutting labor costs by up to 60% compared to traditional plaster and wood paneling.
For exterior application under aggressive sun, rain, and freeze-thaw cycles, Linyi Rich manufactures 360-degree fully capped co-extrusion WPC decking and wall panels. The outer shell comprises an ultra-durable engineering polymer shield that prevents moisture penetration, fading under UV radiation, and stain damage. Perfect for coastal boardwalks, commercial outdoor dining areas, and residential poolside decks, these products retain their color integrity for decades without requiring staining or sealants.
Engineered with a dense core containing 70% natural limestone powder (CaCO3) and 30% PVC polymer, SPC flooring offers maximum dimensional stability. Unlike luxury vinyl tile (LVT), SPC is 100% waterproof and completely resistant to indentation under heavy commercial furniture. Featuring click-lock installation (Unilin patented joints) and attached acoustic Underlayment (IXPE/EVA), SPC floor panels provide superior acoustic damping (Impact Sound Reduction ΔLw up to 19dB).
Our UV-cured PVC marble sheets substitute heavy, expensive natural marble slabs. Utilizing high-definition photographic transfer films coated with double-layer UV-curable fluorocarbon lacquer, these panels provide a Scratch Resistance rating of 3H+ while offering fire resistance (B1 grade). Coupled with our eco-friendly Bamboo Charcoal Wood Veneers—which integrate activated bamboo carbon particles into the PVC matrix for air purification and mold control—designers gain unlimited flexibility for luxury commercial spaces.
Combining aesthetic timber slats with sound-absorbing recycled PET felt backings, our acoustic wall panel collection targets room acoustics (Reverberation Time control). Achieving a Noise Reduction Coefficient (NRC) between 0.85 and 0.95 across human speech frequencies (250Hz - 4000Hz), these panels are tailored for auditoriums, recording studios, conference rooms, and modern open-plan offices. Custom irregular cutting via multi-axis CNC routers enables bespoke architectural layouts.
Tailoring Material Formulations for Specific Geographic Weather Conditions & Global Building Codes.
Formulated with enhanced Hindered Amine Light Stabilizers (HALS) and impact modifiers (CPE), our WPC decking withstands harsh sub-zero temperatures without brittle fracturing, meeting ASTM D7031 and ASTM D7032 performance criteria.
Engineered with elevated thermal deflection temperatures (HDT > 85°C) and anti-static surface treatments. Resists surface heat buildup and prevents sand abrasion in Saudi Arabia, UAE, and Qatar desert climates.
100% compliant with REACH Regulation (EC No 1907/2006), phthalate-free, lead-stabilizer-free, and tested to EN 13501-1 Class B-s1, d0 fire safety standards for public commercial buildings.
Zero water absorption formulations equipped with anti-microbial bio-inhibitors. Prevents mold, algae formation, and structural softening in high-humidity tropical conditions.
