What is 2-layer polymer coated wood plastic?
2-layer polymer-coated wood plastic (2-layer plastic wood) is a new generation composite material combining a wood plastic core (WPC - Wood Plastic Composite) and a polymer coating. This coating has a thickness of 0.1-0.2mm, helping to improve many features of 1-layer plastic wood such as increasing scratch resistance, limiting fading, and a lifespan of up to 20 years.

Structure of 2-layer polymer-coated wood plastic
The composition of 2-layer polymer-coated wood plastic includes 55% wood powder, 35% HDPE plastic, 10% additives, and polymer coating. In which:
- Wood powder has a fineness of 60 mesh to ensure the aesthetics of the product.
- HDPE plastic has a density of 0.93 - 0.97g/cm³, helping the product resist impact well.
- Additives include 4 main types such as: UV absorbers, antioxidants, mold inhibitors, bonding additives that increase plastic flowability, and lubricants.
- Polymer coating has a thickness of 0.1 - 0.2mm, increases scratch resistance, limits fading and creates many product colors.

What are the advantages of Polymer-coated Composite Wood?
With more than 10 years of experience in distributing materials, Kosmos has found that 2-layer wood-plastic materials possess the following 5 outstanding advantages:
- High aesthetics and color stability
- Product life up to 20 years
- Ultimate abrasion and scratch resistance
- Good elasticity and deformation resistance
- Dimensional stability low coefficient of expansion.
High aesthetics and color stability
Advanced manufacturing technology allows 2-layer wood plastic to realistically simulate natural wood grain patterns. This gives the feeling of using real wood while still enjoying the benefits of composite materials.
The outer Polymer layer acts as a protective layer. This layer is not only waterproof and scratch-resistant but also has good UV resistance, helping to keep the product's color stable, minimizing fading or yellowing over time. This ensures that the aesthetics of the space are maintained sustainably, minimizing the need for regular replacement and maintenance.
Long lasting durability up to 20 years
With its special structure and modern manufacturing process, this material is resistant to 5 harsh environmental factors. Including sun, rain, humidity, insects and mold. Product life is up to 20 years.

Excellent abrasion and scratch resistance
Polymer layer increases scratch/abrasion resistance for wood plastic surface. The product is tested for scratch resistance (Abrasion Resistance) according to ASTM D7031-11(2019) section 5,17 & ASTM D4060-19. After 1000 test cycles, the product only lost 24.7g in weight, ensuring good scratch resistance during use.

Good elasticity and deformation resistance
The material has a Creep Factor of 1.12 and a Creep Recovery of 46% according to test method EN 15534-1:2014+A1:2017, showing resistance to deformation under prolonged loading and significant recovery after unloading.
At the same time, with a bending force of 36MPa and a bending modulus of elasticity of 3.73GPa (according to test method EN 15534-1:2014+A1:2017 Annex A), 2-layer wood plastic has good bending load resistance and high hardness.
Dimensionally stable, low coefficient of thermal expansion
The coefficient of thermal expansion is 73×10⁻⁶ K⁻¹ (according to EN 15534-1:2014+A1:2017 Section 9.2 & ISO 11359-1-2014 & ISO 11359-2:1999 Method A) which means that the 2-skin wood plastic material is less likely to expand or contract due to temperature changes, helping to maintain structural stability.

With a mass change rate when boiling of only 0.18% (according to test method EN 15534-1:2014+A1:2017), this material also shows good dimensional stability, little deformation or change when exposed to high temperatures and water.
