Why Does Yongte Recommend That WPC Manufacturers Equip WPC Co-extrusion Machine?

As a professional manufacturer of WPC decking machinery with continuous innovation and technological upgrading, Yongte strongly recommends WPC manufacturers to equip WPC co-extrusion machine to make high quality WPC products. For instance, in a previous project for a Canadian customer, we provided a turnkey co-extrusion system that utilized recycled plastic and PCB recycled fiberglass for the core WPC layer, paired with weather-resistant material for the surface layer. Similarly, in our WPC production project for an Indian client, the customer employed road waste mixed with various colored plastics for the core layer, complemented by an anti-aging co-extruded surface layer featuring custom colors. Additionally, our Romanian customer has adopted the co-extrusion system to replace traditional single-layer WPC, now offering products with over 10 years of warranty.

Process and Structural Innovation Of WPC Co-extrusion Machine

The co-extrusion process enables synchronized extrusion of multi-layer materials, forming a "sandwich" structure—comprising a wear-resistant surface layer, a tough intermediate structural layer, and a moisture-proof base layer. Each layer achieves high interfacial bonding strength (e.g., 1.2MPa), ensuring stable overall performance. Compared to traditional single-material pressing, co-extruded wood-plastic flooring represents a qualitative leap in outdoor durability, stability, and aesthetic appeal, making it the ideal choice for outdoor flooring applications.

Core performance advantage of WPC co-extrusion products

The core performance advantage of co-extruded wood-plastic outdoor flooring lies in its composite structure formed by synchronous extrusion of multiple layers. The key innovation is the application of a high-density, wear-resistant, and weather-resistant co-extruded surface layer over the wood-plastic substrate, achieving comprehensive upgrades in performance, durability, maintenance, and environmental sustainability, making it ideal for complex outdoor environments.

1. Weather resistance and anti-aging: The co-extruded surface layer (e.g., ASA) exhibits high UV resistance and fading resistance, with a fading rate of ≤5% after 1000 hours of UV aging test. Some products maintain a grade 4 or higher appearance even after 10000 hours of testing, with an outdoor service life of 15-60 years. The dimensional change rate under thermal cycling (82°C to-40°C) is ≤0.3%, effectively preventing warping and deformation.

2. Waterproof, moisture-resistant, and mold-proof: The 360° co-extruded coating layer with near-zero water absorption completely blocks moisture penetration, preventing mold growth, rot, and cracking. Ideal for humid environments like coastal areas and swimming pools.

3. Wear-resistant and scratch-resistant: The surface hardness reaches 82HDB, offering 4-5 times greater wear resistance than standard wood-plastic composites. It withstands daily foot traffic, heavy object pressure, and friction, reducing scratches and maintenance costs.

4. Stability and Mechanical Properties: The multi-layer composite structure achieves a dimensional variation rate of ≤0.1%, exhibits minimal bending performance fluctuations, and outperforms traditional outdoor building materials in load-bearing capacity. It meets B1 fire resistance rating, self-extinguishes when removed from flame, and emits no toxic gases.

5. Insect-resistant and termite-proof: The wood fibers are coated with functional plastics, which repel insects such as termites and wood-boring insects, thereby preventing damage and extending the service life.

Cost and Application Value WPC co-extrusion products

1. Low maintenance costs: No paint or renovation required, just regular water rinsing, significantly reducing long-term maintenance expenses.

2. Economical installation and transportation: The hollow co-extruded structure is lightweight, reducing transportation and installation costs, making it suitable for large commercial projects.

3. Appearance and Environmental Protection: It can mimic natural wood grain and be formulated in various colors to approximate the texture of raw wood. Made from recycled plastic and wood fiber, it has a formaldehyde emission level ≤0.1mg/L, with environmental protection indicators surpassing those of traditional materials.
