3mm Good Quality PVC Marble Sheet

Observe the appearance
Texture clarity: The texture of a good quality PVC marble board is clear and natural, with a high degree of similarity to natural marble, and there will be no blur, ghosting or distortion. If the texture is messy and the lines are not smooth, the quality may be poor.
Color uniformity: The color of a high-quality board is uniform, without obvious color difference, color spots or discoloration. For example, the entire board should present a consistent tone, and there will be no partial color that is too dark or too light.
Surface flatness: Place the board flat on a horizontal surface and check it with the naked eye or hand. The surface should be smooth and flat, without defects such as unevenness, bubbles, pits or scratches.
Test physical properties
Flexibility: Gently bend the board. A good quality PVC marble board has a certain flexibility and will not break easily. It can return to its original shape after bending without obvious creases.
Hardness: Use an object with a slightly higher hardness (such as a key) to gently scratch an inconspicuous part of the board. The surface should not easily have obvious scratches. If the scratch is very deep, it means that the board is not hard enough and the quality may be poor.
Waterproofness: Drop a few drops of water on the surface of the board and observe for a period of time. The water should be able to form water beads on the surface and not penetrate for a long time. If the water is quickly absorbed or leakage occurs, it indicates that the board has poor waterproof performance.
Analyze the material composition
PVC purity: High-quality PVC marble boards are usually made of high-purity PVC raw materials. You can check the product test report or consult the merchant to understand the purity and quality grade of PVC. The higher the purity, the better the performance and quality of the board.
Additive quality: In order to enhance the performance of the board, some additives such as stabilizers and plasticizers are added during the production process. The additives used in high-quality boards are of high quality, which can ensure the stability and durability of the board in different environments.
