Direct factory supply featuring advanced thermal stability, high flame retardancy, and automated dimensional extrusion accuracy.
Linyi Rich New Materials Co., Ltd. is a modern industrial enterprise integrating research & development, polymer chemistry engineering, automated extrusion manufacturing, and global supply chain logistics. Headquartered in Linyi City, Shandong Province—Asia's premier hub for composite materials—the company operates a state-of-the-art 100,000 square meter intelligent production base.
Driven by a workforce of over 300 professional technicians and material scientists, Linyi Rich operates at the intersection of eco-friendly formulation design and high-capacity extrusion. As an authoritative OEM/ODM partner for global distributors, project specifiers, and architectural contractors, our custom Listone WPC (Wood-Plastic Composite) lines set benchmark standards for dimensional tolerances, fire retardancy, and structural resilience.
How advanced matrix composite technology is displacing traditional timber and stone in modern commercial construction.
Commercial and high-density residential developments have historically relied on solid timber, real stone veneers, and medium-density fiberboard (MDF). However, these materials pose persistent structural vulnerabilities: solid wood exhibits hygrothermal instability causing warp, checking, and rot under variable relative humidity ($RH > 65\%$); MDF releases formaldehyde VOC emissions and degrades rapidly in moisture-prone zones; natural stone introduces massive dead-load weight penalties requiring reinforced substructures.
Listone WPC bridges the mechanical gap by compounding 60% micro-milled bamboo/hardwood fibers with 30% recycled high-density polyethylene (HDPE) or PVC matrixing, combined with non-toxic chemical coupling agents. This achieves near-zero moisture absorption (<0.5%) while preserving the tactile aesthetic of linear slatted wood ("Listone").
With international building codes enforcing strict Life Cycle Assessments (LCA) and Environmental Product Declarations (EPD) aligned with ISO 14025, real estate developers demand zero-deforestation exterior cladding and interior wall paneling.
As a leading Custom Listone WPC Manufacturer & Factory, Linyi Rich utilizes closed-loop thermo-recycling. Our co-extrusion technology embeds ultra-violet stabilizers (UV-9) and hindered amine light stabilizers (HALS) within the outer shell layer, guaranteeing a 15-to-25 year operational lifespan without toxic chemical paints or recurring oil sealants.
Rigorous laboratory metrics validated through Intertek, SGS, and ISO 9001 quality management protocols.
Engineered with micro-encapsulated ammonium polyphosphate flame retardants, achieving EN 13501-1 Class B-s1, d0 and ASTM E84 Class A ratings for minimal smoke release.
Linear Thermal Expansion Coefficient of $\le 0.15\%$ across operational climate extremes (-40°C to +65°C), preventing wall buckling, joint gaps, or profile distortion.
24-hour immersion water absorption rate under $0.35\%$. Immune to swell damage, fungal decay, termite infestation, and bacterial degradation in high-humidity zones.
