Carbon‑crystal wall panel (Bamboo‑Charcoal Co‑extruded Wall Panel) is a new‑generation eco‑friendly interior decorative board. It is integrally formed by high‑temperature co‑extrusion with PVC (Polyvinyl Chloride) as the base material and bamboo‑charcoal powder as filler. The panel features stable structure, low thermal expansion and contraction rate, anti‑deformation and anti‑cracking. Its high‑quality UV wear‑resistant surface provides rich patterns including marble grain, wood grain, skin‑touch solid colors, suitable for whole‑house renovation, hotels, shops and other indoor decoration projects.
