How to distinguish between the quality and inferiority of resin tiles?

Identifying Products Made from Recycled Granules: Generally, recycled granules contain many residues, so the characteristics of the produced resin tiles are significantly weakened compared to those made from natural materials, such as color discrepancies, impurities that are prone to fading; the bottom is not smooth, and there are many small uneven particles, which are indicative of the use of purchased materials. When burned, they emit a pungent smell, which may be harmful to the body. Resin tiles made from purchased materials are dull in color, lack surface luster, may have small black spots, are prone to cracking, and have a short lifespan.

2. Carefully inspect the overall surface and bottom layer of the resin shingles for smoothness and symmetry. Some manufacturers, due to being newly established, may not adjust their machinery promptly, or they might use production equipment with a long lifespan that was replaced by a large-scale factory, leading to an unevenly flat pressing surface on the resin shingles or inconsistent colors.

3. Place the resin shingles on the ground and stomp on the peak weld to test them. Shingles of the same thickness should not be too soft or too hard. Too soft is due to an excessive amount of plasticizer, making the shingles unsafe for construction, and they will age quickly, leading to potential issues like dents on flat roofs after installation. Too hard is because of too much calcium carbonate, making the shingles brittle and prone to cracking. This degree is quite difficult to assess. Here's how to put it: Avoid resin shingles that become flat with a peak weld and cannot instantly return to shape when released. Cracks indicate an excess of calcium carbonate, and inability to return to shape instantly suggests too much plasticizer.

4. High-value resin tiles, when roasted with an open flame, will extinguish upon removal from the fire source, causing a small amount of white smoke. Counterfeit resin tiles, when roasted, produce a lot of odors and smoke, and continue to burn after the flame is removed.

High-quality resin shingles have a lifespan of nearly 30 years. When purchasing resin shingles, closely inspect the overall surface and bottom layer for any defects. Bend or step on the shingles to see if they easily break. Also, check for product inspection reports. This method can help you reasonably distinguish the quality of resin shingles.
