Technical specifications of Kosmos 2-layer polymer coated outdoor wood plastic

Kosmos 2-layer outdoor wood plastic with Polymer coating (2-layer wood plastic) is a composite material made from 55% wood powder, 35% HDPE plastic, 10% additives and a 0,1 - 0,2mm thick polymer coating.

The product is widely used in outdoor applications such as flooring, wall cladding, gate cladding, stair cladding, hallway cladding. Thanks to the Polymer coating, Kosmos 2-layer plastic wood increases scratch resistance, limits fading, and especially creates many colors according to customer needs.

To evaluate the quality and performance of this material, the specifications have been tested through many standard testing methods. Join Kosmos to learn more details so that customers can clearly understand the information about this material.

Abrasion resistance

Based on the results of the above test method, Kosmos 2-skin wood plastic shows good abrasion resistance with a weight loss of only 24,7 mg after 1000 test cycles according to ASTM D7031-11(2019) Section 5.17 and ASTM D4060-19.

Water absorption rate under boiling conditions

According to the test results, Kosmos Polymer-coated 2-layer wood plastic has a very low water absorption rate, only 0,18% under boiling conditions, demonstrating good water resistance, helping to maintain stability and long-term life up to 20 years when used outdoors.

Coefficient of linear thermal expansion

2-skin wood plastic has a linear thermal expansion coefficient of 73×10-6 K-1, determined according to EN 15534-1:2014+A1:2017 Section 9.2, ISO 11359-1-2014 and ISO 11359-2-1999 Method A. This result shows that the material is able to withstand temperature changes well in outdoor environmental conditions without deformation.

Variation characteristics

According to the test, Kosmos 2-layer polymer-coated outdoor wood plastic has a deformation factor (Cf) of 1,12 and a deformation recovery (Erc) of 46%. The closer the Cf index is to 1, the better, indicating that the material is less likely to deform under load.

The strain recovery index of 46% enables the material to recover nearly half of its deformation after the load is removed, ensuring long-term structural strength for outdoor structures.

Flexural modulus of elasticity and flexural strength

The polymer coated 2-layer wood plastic composite has a bending strength of 36MPa and a bending modulus of elasticity of 3,73GPa, determined according to EN 15534-1:2014+A1:2017 Annex A. These values ​​indicate that the material has ideal stiffness to withstand heavy loads without sagging, making it particularly suitable for load-bearing applications such as outdoor floors, stairs, footbridges, railings.

Minimal possibility of failure

Kosmos Polymer Coated 2-layer Wood Plastic has a high impact resistance of 13,9J when tested according to ASTM D4226-19e1 Procedure A. In practice, the 13,9J level is equivalent to the ability to withstand the impact of a 1,4kg object falling from a height of 1m without cracking or permanent deformation.

This property is especially important for outdoor floors, stairs and high traffic areas where the material is frequently subjected to impact.

Brinell hardness and elastic recovery rate

Kosmos 2-layer outdoor wood plastic has a Brinell hardness of 64MPa and a high elastic recovery rate of 53% according to EN 15534-1:2014+A1:2017 Setion 7.5. This hardness index helps the material surface effectively resist dents caused by concentrated pressure such as high heels, table and chair legs or falling objects.

The 53% elastic recovery rate means that the material can recover more than half of its deformation when the pressure is removed, helping to maintain the aesthetics and durability of the surface even after many years of use, especially in high traffic areas such as terraces, walkways and pool areas.

Rockwell hardness test

Kosmos Polymer Coated 2-layer Wood Plastic achieves a Rockwell hardness of 72R according to ASTM D785-08(2015) Procedure A. This index is in the high segment of the Rockwell scale.

In fact, this hardness allows the material to effectively resist scratches from furniture, children's toys, pet claws and sharp objects commonly encountered in everyday life.

Swelling and water absorption

Kosmos Polymer Coated 2-layer Wood Plastic maintains excellent dimensional stability with extremely low swelling index: 0,17% in thickness, 0,01% in width and 0,02% in length, tested according to EN 15534-1:2014 Seciton 9.6.1 & EN ISO 11925-2:2020.

In a real environment, a 2m long 3-layer wood plastic floor panel will only change its size by a maximum of 0,9mm when exposed to water or high humidity. Complementing this characteristic, the material has a maximum water absorption of only 0,05%, helping to maintain structural stability and effectively prevent mold and rot problems commonly found in materials with high water absorption in humid outdoor environments.

Kosmos 2-layer polymer-coated wood plastic is a high-quality product line that fully meets strict technical standards. With the ability to resist abrasion, water, and good bearing capacity.

Projects such as outdoor floors, railings, pedestrian bridges, stairs, facade cladding, wall cladding will have a lifespan of up to 20 years without complicated maintenance. If you want to know more information about the product, you can contact Kosmos Vietnam warehouse at: Phone: 0903 093 221 .
