1. Environmental friendly, non-pollution, no toxic chemicals.
2. Waterproof, mildew resistant, corrosion resistant.
3. WPC have good workability and can be shaped using conventional woodworking tools.
4. Recyclable.
5. Good appearance, Look like natural wood.
6. Colorful, less maintenance.
The contrast of WPC and Real Wood:
Characteristics | WPC | Wood |
Moisture Resistance | Waterproof | Water absorptive |
Rot Resistance | Antisepsis | Rot except special treating |
Split Resistance | No Cracked | Cracked by weathering effect |
Distortion Resistance | Almost no Contraction/expansion | Distorting effected by chang of moisture and temperature |
UV Resistance | High Grade UV Resistance | Easily effected by UV |
Fading Resistance | Almost no | Easy to fade |
Outdoor adaptability | Great | Only few of treatedowood adaptive |
No need painting | No need | Need paint periodically |
Durable/longevity | > 25 years | < 5 years |
Various Configuration | Extruded via various mould | simplex |
Environment Effect | Recyclable 90% | Consume woods |
As a product for outdoor use, COOWIN has high requirements for product performance. In addition to meeting the basic needs of most of the world, COOWIN’s R&D department has developed special wood-plastic products for extreme weather such as extreme temperatures, high humidity and strong corrosiveness to meet the needs of special application.
