WPC outdoor board is a special outdoor decorative board made of wood fiber or bamboo fiber as the core raw material, compounded with PVC resin, calcium carbonate powder and anti-ultraviolet additives through high temperature and high pressure process. The surface adopts UV curing coating or high-precision imitation wood/stone grain transfer technology, which combines the texture of natural wood with the weather resistance of plastic, and has the characteristics of waterproof and moisture-proof, mildew-proof and antibacterial, anti-ultraviolet, fire-retardant, etc. It is suitable for scenes such as garden landscape, exterior wall decoration, outdoor furniture, etc., and is an environmentally friendly alternative to traditional antiseptic wood and stone.

Landscape​​​​Trails/Plank Road​​ : Anti-slip surface (friction coefficient ≥ 0.6), resistant to humid environment (water absorption rate ≤ 0.3%).​​

Flower box/tree pond​​ : Corrosion resistant (acid and alkali resistant pH value 3-11), suitable for long-term outdoor exposure.

​​Building exterior​​​​

Exterior wall decorative panels​​ Anti-ultraviolet (accelerated aging test ΔE≤3.0), reduce fading.

​​Awning/sunshade​​ : Fire protection grade B1 (flame spread time ≥ 30 minutes), high safety.​​

Commercial facilities

​​​​Hotels/Resorts​​ : Customized 3D relief modeling to enhance the landscape design sense.​​

Restaurants/Cafes​​ : Easy to clean surface (oil resistance test ≥ level 5), low maintenance cost.​​

Public Facilities​​​​

Park benches/trash cans​​ : Antibacterial and mildew-proof (antibacterial rate ≥ 99%), suitable for high-traffic environments.​​

Subway station/Airport​​: Strong weather resistance (stable from -40℃ to 70℃), in line with public safety standards.

Super weather resistance​​ Anti-UV additives + surface coating, weather-resistant life ≥ 15 years (no fading, no peeling).​​

Environmental safety

​​The raw materials are formaldehyde-free, heavy metal-free, CARB/FSC-certified, and 100% recyclable.

​​Diversified Design​​ Supports 100+ effects such as imitation wood grain, stone grain, 3D relief, etc., and can customize gradients and artistic patterns.​​

Easy installation​​ Clip-on/keel installation (no glue required), modular assembly, shortening construction period by 70%.​​

Economical​​ The overall cost is lower than that of antiseptic wood (the price is about 1/2 of that of antiseptic wood), and the maintenance cost is low (no need to refresh with paint).

​​Functional integration​​ LED light strips and sensors can be integrated to achieve intelligent lighting or environmental monitoring (customization required).

​​Raw material handling​​​​

Wood fiber modification​​ ：The wood powder is carbonized and dried (moisture content ≤ 8%) to enhance its compatibility with plastics.​​

Anti-aging formula​​ : Add hindered amine light stabilizer (HALS) and UV absorber (UV-Absorber) to improve weather resistance.​​

Extrusion​​​​Twin screw coextrusion​​ : PVC substrate and wood fiber are mixed and extruded at 180℃-220℃, and the thickness error is ≤±0.2mm.

​​Imitation wood grain technology​​ : Vacuum thermal transfer technology, texture clarity up to 1200dpi, adhesion ≥ level 1 (ASTM D3359).​​

Surface treatment​​​​

UV paint​​ : Three-coat-one-bake process, film thickness ≥40μm, wear resistance up to 10,000 revolutions (Taber test).​​

Hydrophobic structure​​ : Surface micropore design (pore diameter 0.5-1mm), drainage efficiency increased by 50%.

​​Quality Inspection​​​​

Fire test​​ : GB 8624 standard, B1 flame retardant.​​Environmental certification​​ : Passed CARB certification, CE certification (EU), China Environmental Labeling (Ten-Ring Certification).​​

Special Process

​​​​Anti-creep design​​ Add a glass fiber reinforcement layer (5%-10%) to reduce long-term load-bearing deformation.​​

Edge protection​​: Rounded corners/beveled edges (R angle ≥ 3mm) to prevent bumps and improve aesthetics.
