Comparison of QIFA SUR WPC and PRE WPC

"SUR" and "PRE" are two categories of QIFA WPC products differentiated based on their manufacturing processes. "PRE" is the first-generation wood-plastic composite product, made by mixing wood fibers, HDPE, and additives, and then heating and extruding the mixture. "SUR" is an upgraded version of the PRE product, also known as co-extruded WPC. It has at least two layers of structure, with the same material used for the core as in PRE, while the outer layer is covered with a 360-degree capped polymer composite for enhanced durability and protection.While both SUR WPC and PRE decks can be used for producing outdoor flooring,

The differences between SUR and PRE can be explained from several typical perspectives, including the manufacturing process, structure, material, performance, and environmental friendliness. Here we can illustrate the comparison as follows.:

Differences between SUR and PRE

1. Manufacturing Process:

PRE WPC is usually manufactured using a single extrusion process, while SUR WPC involves an additional extrusion process where a protective layer is added to the surface of the board. In the case of SUR, the two-layer co-extrusion process involves an inner core made of recycled wood fiber and plastic, and an outer layer made of a polymer composite that provides protection from the elements.

2. Structure:

PRE WPC usually has a homogeneous structure, while SUR WPC has a layered structure with a core and an outer layer. The core of both products is made from recycled wood fiber and plastic, but the outer layer of SUR WPC is made of a polymer composite that adds protection and improves the appearance.

3. Material:

Both products use recycled wood fiber and plastic, but the composition and quality of the materials may differ. In SUR WPC, the outer layer is made of high-quality polymer composites that improve durability, resistance to moisture, and UV radiation.

4. Performance:

SUR WPC has superior performance compared to PRE WPC. The polymer composite layer on the surface of the SUR WPC provides superior protection from the elements, making it more durable, resistant to moisture, and UV radiation. This makes it a better choice for outdoor applications such as decking, wall cladding, and fencing.

5. Environmental Friendliness:

Both products are considered environmentally friendly because they use recycled materials. However, SUR WPC is more environmentally friendly because it requires less maintenance and replacement compared to PRE WPC. The protective layer on SUR WPC reduces the need for painting, staining, or sealing, reducing the amount of chemicals needed to maintain the product. Additionally, the longer lifespan of SUR WPC reduces the amount of waste generated from replacements.

6. Colors:

SUR WPC decks have a wider range of color options and can simulate a variety of natural wood colors and textures, while PRE decks have relatively fewer color options.

Price Comparison of SUR and PRE

In general, SUR wpc are more expensive than PRE wpc due to their higher manufacturing costs.SUR (Co-extruded) WPC products require additional layers of materials and more complex production processes, which drive up the cost.

However, the exact price difference between SUR wpc and PRE wpc may vary depending on various factors such as the specific product, manufacturer, and region. Additionally, other factors like the size and complexity of the project, installation requirements, and maintenance costs should also be considered when comparing prices.

Overall, while SUR wpc may be more expensive upfront, their longer lifespan, reduced maintenance requirements, and superior performance compared to PRE WPC products may make them a more cost-effective choice in the long run.

Technical Comparison of SUR and PRE

1. Production Process: The production process of SUR wpc involves a co-extrusion process that combines two or more materials together to form a single product. In contrast, PRE wpc is made by mixing wood fibers, plastic, and additives, and then extruding the mixture to form the final product.

2. Material Composition: The material composition of SUR wpc is more complex than that of PRE wpc. SUR wpc typically consists of a core material made of recycled plastic and wood fiber, and an outer layer made of a protective polymer coating. In contrast, PRE wpc is typically made of a mixture of plastic and wood fiber, with no protective coating.

3. Surface Texture: SUR wpc has a more uniform and consistent surface texture than PRE wpc, thanks to the co-extrusion process that creates a smooth outer layer. PRE wpc may have a more textured surface due to the use of natural wood fibers.

4. Durability: SUR wpc is generally more durable than PRE wpc, thanks to the protective polymer coating on the surface. This coating helps to protect the material from scratches, fading, and staining.

In contrast, PRE wpc may be more susceptible to damage from weathering and other environmental factors.Overall, although PRE decks have some advantages as a traditional outdoor decking material, SUR WPC decks have more advantages, better meet the needs of users, and have a more optimistic development trend in the future.
