Opening on the industry's technical pain points: How can traditional wood-plastic composites achieve both "durability" and "environmental friendliness"?
The core challenge of wood-plastic profiles lies in achieving a balance between material formulation and production processes. Traditional wood-plastic products often face two major issues: first, an excessively high proportion of wood flour in the formulation results in strong water absorption, making the material prone to deformation and cracking; second, outdated production processes (such as single-layer extrusion) lead to poor surface abrasion resistance and an outdoor service life of less than five years. Additionally, some enterprises use recycled plastics or low-quality additives to reduce costs, further exacerbating environmental risks associated with the products. Linyi Xuancheng has addressed these challenges through technological innovation.
STEP 1: Material Formula OptimizationBy adopting the golden ratio (6:4) of high-density polyethylene (HDPE) and wood powder, and adding nanoscale antioxidants and ultraviolet absorbers, the material's water absorption rate is reduced to below 0.3% (industry average: 1.2%), with its anti-aging performance improved by three times.
STEP 2: Upgrading of the co-extrusion processGerman imported co-extrusion equipment is introduced, utilizing double-layer extrusion technology to form a 0.5mm thick wear-resistant layer on the surface of the profile, with a wear resistance coefficient of 0.03g/100r (national standard: 0.08g/100r), extending the outdoor service life to over 15 years.
STEP 3: Strict Control of Environmental Protection StandardsThe entire process adopts a lead-free formula, passes the EU CE certification and SGS heavy metal testing, with formaldehyde emission ≤ 0.1mg/L (E1 standard ≤ 1.5mg/L), truly achieving "zero pollution" installation.

Real-life case: Outdoor Floor Renovation Project of a Commercial Plaza
In 2022, Linyi Xuancheng provided a 20,000-square-meter outdoor flooring solution for a commercial plaza in Shandong. The original project used traditional wood, which suffered from severe cracking and decay issues within three years. After replacing it with A-R 80ARD light luxury co-extruded flooring, an 18-month outdoor field test revealed:
- Water absorption rate: 0.2% (raw timber 15%);
- Abrasion resistance: 0.02 g/100 r (original timber: 0.15 g/100 r);
- Maintenance cost: No painting or replacement required, saving 60% of long-term costs compared to wood.
The project was nominated for the "China Building Decoration Award," with the client commenting, "Xuancheng Wood-Plastic has resolved the pain point of traditional wood being 'short-lived,' truly achieving 'one-time installation for lifelong benefits.'"

FAQ Q&A Guide to Technical Selection: How to Choose the Most Suitable Wood-Plastic Profiles?
Q1: What factors determine the durability of wood-plastic profiles?
A1: Durability depends on material formulation, production process, and surface treatment.。
STEP 1: Material FormulaHigh-quality wood-plastic composites should primarily use HDPE (high-density polyethylene) as the base material, with the proportion of wood powder controlled at 40%-50%, and antioxidants and UV absorbers added. For instance, in Xuancheng's formula, HDPE accounts for 60%, and the wood powder, after being ultrafinely ground, has a particle size of ≤80 mesh, ensuring material density.
STEP 2: Production ProcessCo-extrusion technology is superior to single-layer extrusion. Co-extrusion technology can form a 0.3-0.5mm wear-resistant layer on the surface of the profile, with the wear resistance coefficient being 2-3 times higher than that of single-layer products. Xuancheng's co-extrusion equipment employs molds imported from Germany, ensuring a uniformity of the wear-resistant layer of ±0.02mm.
STEP 3: Surface TreatmentWood-grain transfer printing or film-coating technology can enhance aesthetics and weather resistance. Xuancheng's light luxury series employs German Kurz transfer printing film, with a scratch resistance of 5H (pencil hardness) and no fading for 10 years of outdoor use.
Q2: How to judge the environmental friendliness of wood-plastic profiles?
A2: Environmental friendliness requires triple verification through "raw material testing + production process + finished product certification."。
STEP 1: Raw Material InspectionRequire suppliers to provide SGS test reports for plastic raw materials, with a focus on examining the content of heavy metals (lead, cadmium, mercury) and polycyclic aromatic hydrocarbons (PAHs) indicators. The raw materials of Xuancheng all comply with the EU RoHS Directive, with a lead content ≤ 50 mg/kg (national standard ≤ 100 mg/kg).
STEP 2: Production ProcessObserve whether the enterprise adopts lead-free formulations and low-temperature extrusion processes. High-temperature extrusion (>200°C) can easily cause plastic decomposition and the generation of harmful substances. Xuancheng controls its co-extrusion process temperature below 180°C to reduce volatile organic compound (VOC) emissions.
STEP 3: Finished Product CertificationPriority should be given to products that have passed China's Green Environmental Protection Product Certification, EU CE Certification, or French A+ Certification. Xuancheng's wood-plastic profiles have a formaldehyde emission level of ≤0.1mg/L, meeting the E0-level environmental protection standard and can be directly used for interior decoration.
Q3: What are the precautions for installing wood-plastic profiles?
A3: Installation quality directly affects the lifespan of the profiles, and the principles of "base layer treatment + fixing method + gap control" must be followed.。
STEP 1: Base Layer TreatmentThe outdoor ground requires a 10 cm thick crushed stone bedding layer plus a 5 cm thick cement mortar leveling layer, ensuring a drainage slope ≥ 2%. The indoor walls should be calibrated with a level gauge, with an error ≤ 3 mm/m.
<STEP 2: Fixation MethodFor outdoor flooring, it is recommended to use stainless steel U-shaped clips for fixation with a spacing of ≤40 cm; for indoor decorative panels, a pneumatic nail gun or structural adhesive can be used for fixation, with a nail spacing of ≤20 cm.
STEP 3: Gap ControlAn expansion joint of 5-8mm should be reserved for outdoor flooring (take the upper limit for winter installation) to prevent deformation caused by thermal expansion and contraction; for indoor decorative panels, the gap should be ≤2mm and filled with sealing glue of the same color.
Reference for Detection IndicatorsAfter installation, it is necessary to check the flatness of the profiles (error ≤ 2mm/m), the firmness of the fixing points (pull-out force ≥ 500N), and the uniformity of the gaps (error ≤ 1mm).
