How do plastic tiles keep their surface smooth?

Plastic tiles, such as PVC plastic board sheets and synthetic slate roof tiles, are designed to maintain a smooth surface through various mechanisms. One method is to use a special coating or treatment that prevents dirt and grime from sticking to the surface. This allows rainwater to easily wash away any accumulated debris, keeping the tiles looking clean and smooth.

Another technique involves the use of a self-cleaning mechanism. For example, resin tiles achieve a similar self-cleaning mechanism by imitating the microstructure design of the lotus leaf surface. The tiny undulations on its surface can reduce the contact area between water droplets and the surface, making it easier for water droplets to roll away attached dust and dirt.

In addition, some plastic tiles, such as ASA roof tiles, are made with superior materials that resist staining and discolouration. This helps to maintain the smooth surface of the tiles over time.

Overall, plastic tiles stay smooth through a combination of innovative coatings and surface designs that prevent dirt from clinging to the surface. This not only ensures the aesthetic appeal of the tiles but also contributes to their longevity and performance.
