What Is 3rd Generation ASA Co‑extruded WPC Wall Cladding And How It Outperforms Older Versions

1st Generation Standard Single Layer WPC Wall Panel Disadvantages

The first generation WPC wall cladding is a traditional single layer wood plastic composite board made of wood powder and plastic raw materials through single extrusion molding. This early WPC material has simple production process and low cost so it was widely used in early interior and partial outdoor decoration.

However standard single layer WPC has poor UV resistance. There is no protective layer on the board surface. When exposed to direct sunlight ultraviolet rays will penetrate the surface and damage the internal wood fiber structure. After several months or years of outdoor use the panel will appear obvious fading whitening and surface chalking. The service life in open air environments is very limited. For this reason first generation single layer WPC is only suitable for indoor walls shaded corridors and non exposed areas not for outdoor facade projects.

2nd Generation PE Co Extruded WPC Wall Panel Limitations

The second generation WPC optimizes the surface protection structure adopting PE co extrusion technology. A PE protective layer is covered on the basis of traditional WPC substrate. Compared with the first generation single layer WPC the color retention and surface durability have been improved to a certain extent.

Even so PE co extruded WPC still has obvious limitations in high UV environments. The PE material cannot resist strong ultraviolet radiation for a long time. In high temperature strong sunlight and coastal salt spray areas the PE protective layer will gradually age crack and lose its protection ability. The color fading problem cannot be completely solved. The second generation PE co extruded WPC can only meet short term outdoor use and is not suitable for high standard villa exterior walls hotel facades and long term outdoor engineering projects.

3rd Generation ASA Co Extruded WPC Wall Panel Core Advantages

The third generation ASA co extruded WPC wall cladding is the latest upgraded outdoor wall panel technology which completely solves the fading and aging pain points of the first and second generation products. It adopts true double layer co extrusion technology integrating high performance ASA cap layer and WPC substrate at high temperature.

The high performance ASA cap layer has excellent anti UV performance and super color stability. It can effectively isolate ultraviolet radiation rain erosion and coastal salt spray corrosion. The internal WPC substrate maintains high toughness waterproof performance and structural stability. Different from fake laminated panels genuine ASA co extruded wall panels are integrally formed without glue bonding and will not peel off or crack after long term outdoor use.

Third generation ASA co extruded WPC wall cladding has ultra long outdoor service life low maintenance cost and stable appearance. It is the most suitable outdoor wall siding for villa exterior walls courtyard fences balcony facades hotel decoration and coastal architectural projects.
