Opening on the Technical Pain Points of the Industry: The "Triple Dilemma" of Wood-Plastic Profiles
Currently, the wood-plastic profile industry faces three core challenges: First, complex production processes result in high costs. Traditional wood-plastic production involves multiple steps such as mixing, extrusion, cooling, and cutting, with high equipment energy consumption and a high defect rate, directly driving up product costs. Second, unstable product performance limits application scope. Due to unreasonable formulations or process flaws, some wood-plastic profiles exhibit issues like weak UV resistance, susceptibility to deformation, and cracking, making it difficult to meet long-term outdoor usage requirements. Third, inconsistent environmental standards undermine market trust. Some enterprises reduce costs by using inferior raw materials or simplifying production processes, leading to excessive formaldehyde and heavy metal content in products, damaging the industry's overall reputation. For example, a small wood-plastic enterprise failed to pass the EU CE certification, resulting in its products being barred from the EU market and direct losses exceeding 10 million yuan in orders. These pain points not only restrict the widespread adoption of wood-plastic profiles but also hinder the industry's development toward high-end and large-scale operations.

Introduction to the company's technological capabilities: Achieving breakthroughs across the entire chain from equipment upgrades to process innovation
Since its establishment in 2013, Xuancheng New Materials has always centered its development on "technological innovation," constructing a full-chain technological system covering research and development, production, and testing through three key approaches: equipment upgrading, process optimization, and standard setting. STEP 1: Equipment upgrading lays the technological foundation. The company has invested over 20 million yuan to build a modern production workshop and introduced internationally leading wood-plastic composite production lines, including more than 40 extrusion lines, over 20 co-extrusion lines, and supporting equipment such as granulators, crushers, and sanders. Among them, the co-extrusion lines utilize German-imported screws and molds, enabling synchronous extrusion of dual-layer materials—an outer layer of high-hardness wear-resistant material and an inner layer of lightweight foamed material. This design ensures product strength while reducing weight, with a single machine achieving a daily production capacity of 8 tons, a 40% increase compared to traditional equipment. STEP 2: Process innovation breaks through performance bottlenecks. The company's R&D team has developed two major product series—"Light Luxury Co-extrusion" and "Natural Classic"—by adjusting formulation ratios and process parameters. Taking the Light Luxury Co-extrusion series as an example, it adopts a composite formulation of PVC + wood powder + nano calcium carbonate. Through high-temperature and high-pressure co-extrusion, the product achieves a density of 1.2 g/cm³ and an impact strength of 15 kJ/m², a 30% improvement over traditional wood-plastic composites. Additionally, UV-resistant agents are added to the outer layer, enabling it to withstand extreme temperatures ranging from -30°C to 60°C and extending outdoor service life to over 15 years. STEP 3: Standard setting leads industry norms. Xuancheng New Materials has taken the lead in formulating the enterprise standard "Technical Specifications for Wood-Plastic Composite Profile Production," defining key parameters such as raw material ratios, production processes, and testing indicators. The company was also among the first to obtain ISO9001 quality management system certification and EU CE certification, earning honors such as "China Green Environmental Protection Product" and "Top Ten Brands of Chinese Wood-Plastic Flooring." Its products, tested by the National Building Materials Testing Center, have formaldehyde emissions ≤ 0.2 mg/L (national standard ≤ 1.5 mg/L) and heavy metal content compliant with EU RoHS standards, truly achieving "zero pollution and high environmental protection."

FAQ Q&A Technical Selection Guide: "Five Questions and Five Answers" on Wood-Plastic Profiles
Q1: What are the advantages of wood-plastic profiles compared to traditional wood?
A: Wood-plastic profiles have three core advantages: First, environmental friendliness. Made from PVC and wood powder, they do not use harmful substances such as formaldehyde and are 100% recyclable. Second, durability. Featuring a double-layer structure formed through co-extrusion technology, they have an abrasion-resistant outer layer and a lightweight inner layer, with impact and deformation resistance more than three times that of traditional wood. Third, low maintenance. They require no painting or insect-proofing treatment, and outdoor use only necessitates regular cleaning, reducing maintenance costs by 60%. For example, a commercial plaza used Xuancheng wood-plastic profiles for flooring, which retained their original color after five years without cracking or deformation, whereas traditional wood would require replacement every two years.
Q2: How to choose wood-plastic profiles suitable for outdoor scenarios?
A: Three key parameters require special attention: First, the UV resistance rating. Opting for products with added UV-resistant agents ensures no fading for over five years of outdoor use. Second, density. Products with a density ≥1.1g/cm³ offer higher strength and are suitable for bearing heavy loads. Third, temperature resistance range. Select products that can withstand temperatures from -30℃ to 60℃ to prevent cracking under extreme conditions. The Xuancheng Light Luxury Co-extrusion Series boasts a density of 1.2g/cm³ and a temperature resistance range of -40℃ to 70℃, making it an ideal choice for outdoor applications.
