Product Details
Exterior WPC Wall Panel 220*21mm
,ASA Exterior WPC Wall Panel
220*21 Next-Gen ASA Co-Extrusion Ultra-Matte Outdoor WPC Wall Panel
Product Summary
Manufactured via synchronized multi-layer thermal co-extrusion, a high-tech ASA (Acrylonitrile-Styrene-Acrylate) engineering polymer shield is molecularly fused over a high-strength composite core. This technical armor leverages the elite UV-stability and weatherproof genes inherent to ASA plastics, completely eliminating common industry points such as surface powdering, yellowing, and sun-bleaching. Featuring a prestigious, deeply realistic ultra-matte timber tactile finish alongside a lifetime zero-maintenance profile, it serves as the definitive upgrade for high-UV regions, coastal facades, and luxury architectural designs.
About this Product
-
Automotive-Grade UV & Yellowing Defiance
-
Utilizing an engineering-grade ASA skin layer, this outdoor WPC wall panel blocks solar radiation at a molecular level, remaining completely immune to the sun-bleaching and chalking that ruins standard PE plastics.
-
-
Non-Plastic Ultra-Matte Aesthetics
-
Bypassing the artificial, glossy reflection of traditional composites, our ASA tech features advanced matte-texturing agents paired with 3D embossing, delivering the inner depth and warmth of natural exotic hardwoods.
-
-
Zero-Delamination Molecular Thermal Fusion
-
The protective ASA shield and WPC core are extruded simultaneously at temperatures exceeding 210°C under immense pressure, cross-linking permanently into a single body that will never peel or blister from -40°C to +85°C.
-
-
Low Surface Tension Eco-Self-Cleaning
-
The chemically inert ASA surface profile creates low surface tension. Stubborn oil grease, charcoal soot, bird droppings, and urban smog cannot bond to the grain, allowing natural rain showers to slide off and clean the facade.

What is“ASA”?
ASA (Acrylonitrile-Styrene-Acrylate) is a high-performance engineering plastic. By replacing the butadiene in traditional ABS with sun-resistant acrylic rubber, it gains an incredibly hardcore profile of ultra-weatherability and UV resistance. It will not yellow, chalk, or crack under intense outdoor exposure, making it widely used for automotive exteriors, premium roofing tiles, and the outer protective layer of high-end second-generation co-extrusion WPC wall panels.

FAQ
Q1: Why is an ASA capped outdoor WPC wall panel superior to standard PE co-extrusion?
A1: Standard PE (Polyethylene) caps can still degrade, fade, or become brittle over 10-15 years of intense UV exposure. ASA is an advanced engineering plastic widely used in automotive exteriors and high-end roofing. It possesses an acrylic rubber molecular chain that is chemically immune to UV rays, providing double the lifespan and vastly superior impact hardness compared to PE.
Q2: Does the ASA wall panel perform well in highly polluted industrial cities or coastal zones?
A2: It performs flawlessly. ASA is highly resistant to chemical aging, making it completely immune to sulfur dioxide emissions in heavy industrial cities and high chloride concentrations in coastal salt-spray areas. It prevents these corrosive elements from ever reaching the structural core fibers, maintaining a pristine facade line.
Q3: What type of screws should be used during installation to maintain the premium quality of the system?
A3: To complement this premium system, we strictly recommend using hidden stainless steel clips with flat-head, self-tapping stainless steel screws. This hardware ensures an unblemished facade finish with no visible screw heads while providing maximum rust resistance against all outdoor elements.
Q4: Can we use standard domestic cleaners to wash the ASA surface if it gets soiled during construction?
A4: Yes, easily. Because the ASA engineering plastic layer is chemically stable and non-porous, construction dust, mud, or chalk marks sit completely on the surface. You can wash them off using standard mild household dish soaps and warm water, or use a domestic pressure washer from a safe distance of 30cm.
