SPC (Stone Plastic Composite) wall panels are a type of engineered material primarily used in interior wall cladding. SPC is a highly durable, waterproof, and eco-friendly material. The components of SPC wall panels typically include:

1. **Stone Powder (Calcium Carbonate):** The “stone” in SPC refers to calcium carbonate (a type of limestone) that is finely ground and mixed with other materials. This gives SPC its rigidity, strength, and density. The high stone content helps to make the panels resistant to impact, scratches, and wear.

2. **Polyvinyl Chloride (PVC):** The “plastic” in SPC refers to PVC, which is the main polymer used in SPC panels. PVC is combined with stabilizers, plasticizers, and other additives to provide flexibility, impact resistance, and waterproof properties. The blend of PVC and calcium carbonate creates a material that is both lightweight and durable.

3. **Additives and Stabilizers:** Various additives are used to improve the performance and durability of SPC panels, including stabilizers to enhance UV resistance, plasticizers for better flexibility, and flame retardants to reduce fire risk.

4. **Wear Layer (Optional):** Some SPC wall panels have a protective wear layer on top, which can be a UV coating or a transparent film, enhancing the panel’s durability and resistance to scratches, stains, and fading. This layer also often gives the panels a polished or textured finish, depending on the desired aesthetic.

5. **Printed Decorative Film (Optional):** SPC panels can also include a printed vinyl film beneath the wear layer, allowing manufacturers to mimic the appearance of various materials, such as wood, stone, marble, or other textures. This allows for customization of the panel’s surface to achieve a wide range of design styles.

SPC panels are commonly used in interior applications like walls, especially in high-moisture environments such as bathrooms, kitchens, and commercial spaces, due to their waterproof nature and easy maintenance. They are also often used for both residential and commercial flooring.
