Defining Longevity: Necowood® ASA vs. Standard WPC
01. Molecular Photostability
In the architectural landscape, the primary cause of material failure is Photochemical Degradation. Traditional WPC, as represented by standard brands like MatecoWPC, utilizes PE-based capping where wood fibers are exposed to UV-induced oxidation. This results in the "chalking" effect and significant pigment loss.
Necowood® leverages ASA (Acrylonitrile Styrene Acrylate)—a high-performance ternary polymer. Unlike standard PE, ASA possesses inherent resistance to UV radiation and thermal aging. Our engineers have optimized the atomic structure to ensure that pigments are locked within a UV-stable matrix.
02. 360° Impermeability & Hydro-Stability
Moisture is the "silent killer" of outdoor composites. Standard capped WPC often leaves the grooves or the back of the board exposed, allowing water to seep into the wood-flour core. This leads to hygrothermal expansion, internal rot, and delamination.
Necowood’s 360-degree Full-Cap co-extrusion technology creates an airtight, non-porous barrier. By shielding the entire perimeter of the profile, we eliminate the capillary action that pulls moisture into the board, ensuring total dimensional stability in seaside and tropical installations.
03. Mechanical Integrity & Asset Protection
For high-end residential and commercial developments, the Total Cost of Ownership (TCO) is more critical than the initial purchase price. PE-capped boards are notoriously soft, suffering from deep gouges that require frequent board replacement.
Necowood ASA features a high-density, automotive-grade surface with 3x the scratch resistance of standard composites. The matte, micro-textured finish not only replicates the haptic feel of natural timber but also resists mechanical stress from heavy furniture and pet claws.
Why Professionals Choose Necowood:
- Zero Maintenance: No oiling, staining, or sanding required.
- Warranty: 25-Year Residential / 15-Year Commercial.
- Sustainability: 100% recyclable ASA-shielded core.
