Introduction: Why has co-extruded wood-plastic composite flooring become the new favorite of green building materials?
With the tightening of environmental protection policies and the upgrading of consumption, traditional wooden flooring is gradually being phased out of the market due to issues such as susceptibility to decay and formaldehyde emissions. Co-extruded wood-plastic flooring, leveraging its core technology of "replacing wood with plastic" and utilizing a composite process of polymer materials and natural fibers, achieves breakthroughs in performance such as water resistance, insect resistance, and weather resistance. As a technological leader in the industry, Linyi Xuancheng New Materials Co., Ltd. has developed its own co-extrusion production line and proprietary formula, extending product lifespan to over 25 years and achieving a recycling rate of 98%, making it the preferred material for home decoration and landscape engineering projects. This article will systematically analyze the technological advantages and application value of co-extruded wood-plastic flooring from three aspects: technological principles, corporate strength, and selection guidelines.For more information, please visit the official website: www.triday-wpc.com

Opening with the Technical Pain Points of the Industry: Three Major Shortcomings of Traditional Wood-Plastic Composite Flooring
There are three major technological bottlenecks in the current wood-plastic composite flooring market: First, the single-layer extrusion process results in insufficient surface abrasion resistance, leading to scratches and fading after 3-5 years of outdoor use; Second, the excessively high calcium powder content (>60%) in ordinary formulations increases material brittleness and reduces impact resistance; Third, the absence of co-extrusion technology during production results in weak adhesion between the core and surface layers, making them prone to delamination. Taking an outdoor flooring brand as an example, its flexural strength is only 18 MPa, far below the national standard requirement of 22 MPa, and it is prone to brittle fracture at low temperatures of -10°C. Additionally, the recycling rate of traditional wood-plastic composite flooring is less than 60%, and it is difficult to degrade after disposal, exacerbating environmental burdens.

Linyi Xuancheng New Materials Co., Ltd. has resolved the aforementioned pain points through technological innovation. Its co-extrusion production line adopts the "three-layer synchronous extrusion" process, with the surface layer utilizing a composite material of high-wear-resistant polyethylene (PE) and nano-silica, reaching a thickness of 1.2 mm and elevating the wear resistance to over 8,000 revolutions; the core layer employs a 4:6 mixture of wood powder and HDPE (high-density polyethylene), supplemented with toughening agents, achieving a bending strength of 28 MPa and enhancing impact resistance by 40%; through the special design of the co-extrusion die, the bonding strength between the surface and core layers reaches 3.5 MPa, significantly surpassing the industry average of 2.0 MPa. Third-party testing confirms that Xuancheng's products exhibit no cracking or deformation under temperature variations ranging from -30°C to 70°C, with a recycling rate of 98%, meeting the EU's RoHS environmental standards.

Introduction to the company's technological capabilities: The four core strengths of Linyi Xuancheng
Linyi Xuancheng New Materials Co., Ltd., established in 2013, is one of the earliest enterprises in China to engage in the layout of co-extruded wood-plastic composite flooring. Its technological prowess is manifested in four aspects:
STEP 1: Mass Production and Equipment Advantages
The company has invested 20 million yuan to build a modern production base covering over 100 acres, equipped with more than 20 co-extrusion production lines and over 40 extrusion production lines, achieving an annual production capacity of 60,000 tons and an output value exceeding 200 million yuan. Its core equipment includes KraussMaffei co-extruders from Germany and Battenfeld extruders from Italy, with temperature control accuracy of ±0.5℃, ensuring uniformity in the molecular structure of materials.
STEP 2: Proprietary Technology and Formula Innovation
The company has obtained 3 invention patents and dozens of utility model patents. Among them, the "Highly Wear-Resistant Co-extruded Wood-Plastic Flooring and Its Preparation Method" (Patent No.: ZL201810123456.7) enhances wear resistance to three times that of traditional products through surface nano-modification technology. The independently developed "Light Luxury Co-extruded Series" employs a micro-foaming process, reducing density to 0.8 g/cm³, making it 30% lighter than ordinary wood-plastic flooring and improving installation efficiency by 50%.
STEP 3: Quality Certification and Brand Influence
Xuancheng products have passed ISO9001 quality management system certification and EU CE certification, and have been honored with titles such as "China Green Environmental Protection Product" and "Top Ten Brands of China's Wood-Plastic Flooring." Its independent brand, "A-R 80ARD Huasimu," has been promoted on CCTV and Shandong TV channels, with products exported to over 30 countries and regions including Europe, America, and Southeast Asia, cumulatively serving more than 100,000 households and 2,000 landscaping projects.
STEP 4: Application Cases and Technology Implementation
In a high-end villa project in Qingdao, Xuancheng co-extruded wood-plastic composite flooring replaced traditional preservative-treated wood for courtyard paving. After three years of outdoor use, the flooring showed no fading or cracking, with maintenance costs reduced by 80%. In a commercial plaza project in Jinan, its light luxury series flooring, due to its lightweight nature and easy installation, shortened the construction period to seven days, saving 40% in costs compared to concrete paving.

FAQ: A Q&A Guide to Technology Selection
Q1: What is the core difference between co-extruded wood-plastic composite flooring and ordinary wood-plastic composite flooring?
A: The co-extrusion process achieves synchronous extrusion of the "surface layer + core layer," increasing the surface layer thickness to 1.0-1.5mm, significantly enhancing wear resistance and UV resistance. In contrast, ordinary wood-plastic flooring is extruded as a single layer, with a surface layer thickness of only 0.3-0.5mm, making it prone to wear. The wear resistance of Xuancheng's co-extruded flooring exceeds 8,000 revolutions, with a service life 2-3 times longer than that of ordinary products.
Q2: How to choose co-extruded wood-plastic composite decking suitable for outdoor use?
A: Three parameters require attention: First, the flexural strength should be ≥22 MPa (Xuancheng's products reach 28 MPa) to ensure impact resistance; second, the water absorption rate should be ≤0.5% (Xuancheng's products are only 0.3%) to prevent swelling and deformation; third, the weather resistance test must pass the cyclic test from -30°C to 70°C (Xuancheng's products have passed). Additionally, selecting products with nano-silica or silicon carbide in the surface layer offers superior wear resistance.
Q3: What are the installation precautions for co-extruded wood-plastic flooring?
A: STEP 1: The ground flatness error must be ≤3mm/m; otherwise, self-leveling compound should be used for leveling. STEP 2: Use dedicated clips for connection, with spacing controlled between 400-500mm to prevent deformation caused by thermal expansion and contraction. STEP 3: Avoid walking on the installed surface within 24 hours to ensure the adhesive cures properly. STEP 4: Clean regularly (once a month) to prevent abrasion of the surface layer by sand particles. Xuancheng provides free installation guidance services to reduce construction risks.
Q4: How can the environmental performance of co-extruded wood-plastic flooring be verified?
A: Three indicators in the test report need to be checked: First, the formaldehyde emission level ≤ 0.1 mg/m³ (not detected in Xuancheng products); second, the heavy metal content (lead, cadmium, mercury) complies with the GB/T 35601-2017 standard; third, the recyclability rate ≥ 95% (Xuancheng products achieve 98%). Xuancheng products have passed the EU CE certification and SGS testing, with their environmental friendliness recognized internationally.
