The SPC Wall Panel Industry Glossary is designed to help professionals, manufacturers, and designers understand the technical language behind Stone Plastic Composite (SPC) wall systems. From production processes and material composition to surface finishes and installation methods, this glossary defines key SPC wall panel terms used throughout the industry. Whether you’re specifying products, managing projects, or exploring new wall cladding solutions, these definitions will enhance communication and technical understanding across the supply chain.
| Term | Definition |
| SPC Wall Panel | Stone Plastic Composite wall panel made from PVC and calcium carbonate for interior decoration. |
| Rigid Core Panel | A solid, durable core panel structure used in SPC wall systems. |
| Extrusion | The process of forming SPC panels by pushing heated material through a mold. |
| Embossing | Surface texture technique that adds realistic stone or wood patterns to SPC panels. |
| UV Coating | A surface protection layer cured with ultraviolet light to resist scratches and stains. |
| Click Lock System | Interlocking mechanism allowing panels to snap together without adhesive. |
| Tongue and Groove | Classic interlocking joint system for secure and seamless wall installation. |
| Hot Press | Thermal process that bonds decorative film onto the SPC core under pressure. |
| Decorative Film | Printed PVC film layer that provides the panel’s color and pattern. |
| Wear Layer | Transparent top layer protecting the surface from wear and fading. |
| PVC Resin | Primary polymer ingredient in SPC composition offering flexibility and durability. |
| Calcium Carbonate | Mineral filler improving rigidity and dimensional stability of SPC panels. |
| Foaming Agent | Additive used to control density and sound insulation properties. |
| Sound Insulation Layer | Backing material reducing noise and improving wall acoustics. |
| Waterproof Core | SPC’s non-porous structure preventing water absorption and swelling. |
| Fire Resistance | The ability of SPC panels to resist ignition and slow flame spread. |
| Formaldehyde Free | Indicates that the product emits no harmful formaldehyde gases. |

| Moisture Barrier | Layer preventing dampness from penetrating the wall structure. |
| Backing Layer | Base layer supporting overall panel strength and adhesion. |
| Vertical Installation | Wall panel fitting direction designed for height-oriented visual effect. |
| Horizontal Installation | Wall panel fitting direction emphasizing width and spatial openness. |
| Seamless Joint | Invisible connection between panels for a smooth appearance. |
| Thermal Expansion | Minor dimensional change of panels under heat variations. |
| Eco-Friendly Material | Environmentally responsible formulation meeting sustainability standards. |
| Wainscoting | Decorative wall paneling covering the lower part of an interior wall. |
| Ceiling Application | Use of SPC panels on ceilings for aesthetic continuity. |
| Wall Cladding | General term for covering walls with decorative protective panels. |
| Interior Decoration | Design process involving SPC panels to enhance wall aesthetics. |
