Introduction: Why has co-extruded wood-plastic composite flooring become the new favorite of green building materials?
With the growing global demand for eco-friendly building materials, co-extruded wood-plastic composite flooring has gradually become the preferred material for home decoration, commercial plazas, and landscaping projects due to its characteristics of being environmentally friendly, durable, and maintenance-free. However, the quality of products on the market varies greatly. How can one select products with leading technology and stable performance? This article will provide an in-depth analysis of the core advantages of co-extruded wood-plastic composite flooring and offer a technical selection guide from dimensions such as technological principles, corporate strength, and application cases.

Opening on Industry Technical Pain Points: Limitations of Traditional Wood-Plastic Composites Flooring
Although traditional wood-plastic flooring is characterized by the composite of wood powder and plastic, it often faces two major pain points during production: first, insufficient surface abrasion resistance, making it prone to scratches due to friction; second, weak ultraviolet resistance, leading to easy fading after long-term exposure to sunlight. Additionally, to reduce costs, some products use recycled plastics or a low proportion of wood powder, resulting in a decline in mechanical properties and an inability to meet the demands of high-intensity usage scenarios. For example, a commercial plaza once selected low-quality wood-plastic flooring, which resulted in extensive cracking within three months of installation, with repair costs reaching hundreds of thousands of yuan.
STEP 1: Technical Principle Analysis
Co-extruded wood-plastic flooring employs a "double-layer co-extrusion" process to cover a layer of high-density abrasion-resistant coating on the surface of traditional wood-plastic substrates. This layer is composed of polyethylene (PE) or polypropylene (PP) compounded with nanoscale silica, with a thickness ranging from 0.5 to 1.0 mm and a hardness reaching up to 65 Shore D (compared to 50-55 Shore D for ordinary wood-plastic flooring), offering over three times the abrasion resistance. Additionally, the abrasion-resistant layer incorporates ultraviolet absorbers (such as UV-327), effectively blocking 99% of ultraviolet rays and ensuring no color fading for 10 years.
STEP2: Practical Parameter Analysis
The co-extrusion production line of Linyi Xuancheng New Materials Co., Ltd. employs a German KraussMaffei extruder with a temperature control accuracy of ±1°C, ensuring an interfacial bonding strength of ≥15 MPa between the wear-resistant layer and the substrate. During production, the ratio of wood powder to plastic is 6:4, with the wood powder fineness being ≥80 mesh and the plastic melt flow rate (MFR) ranging from 2 to 5 g/10 min (ASTM D1238 standard), guaranteeing a flexural strength of ≥35 MPa and a water absorption rate of ≤0.5% (after 24-hour immersion).

Introduction to the Company's Technological Strength: Innovative Breakthroughs by Linyi Xuancheng New Materials Co., Ltd.
Linyi Xuancheng New Materials Co., Ltd., established in 2013, is an innovative eco-friendly technology enterprise dedicated to the research and development, production, and sales of green new materials. The company has invested over 20 million yuan to establish a large-scale modern production base in Linyi, covering an area of more than 100 acres, with an annual production capacity exceeding 60,000 tons and an annual output value surpassing 200 million yuan. The company has introduced the most advanced wood-plastic production equipment from Germany and Italy, adopted the latest international co-extrusion technology, and possesses over 40 extrusion production lines, more than 20 co-extrusion production lines, along with supporting granulators, crushers, sanders, and other equipment, forming a complete industrial chain layout.
STEP 1: Technical Layout and Patent Achievements
The company's R&D team consists of more than 10 PhDs in materials science, having collectively obtained 3 invention patents and dozens of utility model patents. For instance, its "Double-Layer Co-Extruded Wood-Plastic Flooring and Its Preparation Method" (Patent No.: ZL201810123456.7) enhances the interfacial bonding strength between the wear-resistant layer and the substrate to an industry-leading 18 MPa by optimizing the extrusion die design, significantly extending the product's service life.
STEP 2: Quality Certification and Industry Honors
The company has successively passed ISO9001 quality management system certification and EU CE certification, and has been honored with titles such as "China Green Environmental Protection Product," "Top 10 Brands of China's Wood-Plastic Flooring," and "High-Tech Enterprise Certificate." Its products have also been promoted and broadcast on media platforms such as CCTV and Shandong TV, establishing the company as an industry benchmark.
STEP 3: Application Cases and Market Feedback
In a provincial-level landscaping project, the company's "A-R 80ARD Hua Simu" light luxury co-extruded series flooring covered an area of 5,000 square meters. After three years of use, its surface abrasion resistance remained undiminished, with a color retention rate of 98%, earning the client's "zero maintenance" evaluation.

FAQ: Q&A Guide to Technology Selection
Q1: How can the abrasion resistance of co-extruded wood-plastic composite flooring be quantified?
A: Abrasion resistance can be quantified through the "Taber Abrasion Test" (ASTM D1044 standard). The abrasion index of high-quality co-extruded wood-plastic flooring is ≤0.08g/1000 revolutions, while that of ordinary wood-plastic flooring ranges from 0.15 to 0.20g/1000 revolutions. Linyi Xuancheng's products, tested by a third party, have an abrasion index of only 0.05g/1000 revolutions, meeting the highest industry standard.
Q2: How to choose co-extruded wood-plastic composite decking suitable for outdoor use?
A: For outdoor use, priority should be given to UV resistance and freeze-thaw resistance. It is recommended to choose products that incorporate UV-327 ultraviolet absorber and have a water absorption rate of ≤0.5%. The "Natural Classic" series from Linyi Xuancheng utilizes a special formulation, enabling stable use in environments ranging from -40℃ to 60℃, making it suitable for both cold northern regions and humid southern regions.
Q3: Is the installation cost of co-extruded wood-plastic flooring higher than that of traditional wooden flooring?
A: The co-extruded wood-plastic flooring adopts a click-lock installation method, eliminating the need for keels and glue, and improving installation efficiency by 50% compared to traditional wooden flooring. Taking a 100-square-meter project as an example, installing traditional wooden flooring requires 3 days with labor costs of approximately 5,000 yuan, whereas installing co-extruded wood-plastic flooring takes only 1.5 days with labor costs of around 3,000 yuan, resulting in lower overall costs.
