What is WPC co-extruded decking?
As WPC production processes continue to develop, new products are also being developed. A new type of product called co-extruded WPC has gradually come into people's view.
What is co-extrusion technology?
Co-extrusion is a manufacturing process used to make multi-layer wood plastic composite (WPC) deck products. In a co-extrusion system, two or more different plastics or composite materials are extruded simultaneously to form a single unified profile with different layers.
Due to the addition of new processes, co-extruded products are also called second-generation products.
What does WPC co-extruded decking consist of?
Co-extruded WPC decks are composed of multiple layers that are fused together during the extrusion process. Typically, these layers include:
Surface layer: The surface of the co-extruded WPC deck is wrapped with plastic compounds, usually in full-wrapped and half-wrapped forms. The surface mainly provides enhanced scratch resistance, stain resistance and impact resistance.
Core layer: The middle layer that makes up the majority of the profile is composed of standard wood plastic composite materials. This provides core strength, stability.
The co-extrusion process enables manufacturers to design decks that combine the best characteristics of each material into a single, cohesive board. This gives WPC decks superior durability, aesthetics, and performance characteristics compared to traditional single-ply composites.
What is the difference between Co-extruded WPC decks and ?
Layer Construction:
Co-extruded WPC decks have a multi-layer construction, typically with a wear layer, core layer, and backing layer. Standard WPC decks are single-ply, homogenous wood-plastic composites.
Performance Characteristics:
Co-extruded decks have enhanced performance due to the specialized attributes of each layer. The surface wrap layer provides excellent scratch, stain, and impact resistance. The core layer provides structural integrity and dimensional stability. Standard WPC decks have more uniform performance characteristics without specialized layered designs.
Design Flexibility:
Co-extruded decks allow for greater design customization, as different layers can be designed with unique colors, textures, and visual patterns.
Standard WPC decks have a more limited aesthetic range, as the appearance is primarily determined by a single composite material.
Manufacturing Process:
Co-extruded decks are produced using a more complex co-extrusion process that incorporates multiple materials simultaneously.
Standard WPC decks are manufactured using a simpler mono-extrusion process.
Cost:
Co-extruded decks are generally more expensive to manufacture due to the additional complexity of the co-extrusion process and specialized materials.
Standard WPC decks tend to be more cost-effective because they require less intensive production methods.
In summary, co-extruded WPC decks offer enhanced performance, design flexibility, and more complex structures than standard single-ply WPC decks, but are more expensive to manufacture.
