Anti UV Polycarbonate Sheet 4mm-32mm Polycarbonate Sheet Multiwall For Building Material

How to distinguish the authenticity of polycarbonate three-layer hollow plate?
View appearance
Transparency: Genuine polycarbonate three-layer hollow plate has a high transparency, similar to glass, but more texture than glass, can clearly see the other side of the object, and no obvious impurities, bubbles. Inferior or counterfeit products may be less transparent, have a hazy feeling, or have more visible impurities and bubbles.
Color: High quality plate color uniformity, no color difference. If the color of the plate is too white or too yellow, too much recycled material or poor quality additives may be added, and it is necessary to be wary of counterfeit products.
Surface flatness: The surface of the genuine plate is smooth and smooth, without uneven, wavy or pothole defects. Touch with the hand, feel delicate, no rough feeling; If the surface is not smooth, it not only affects the appearance and installation, but also indicates that the production process is backward and the product quality is not reliable.
Perform physical performance tests
Impact resistance: Polycarbonate has good impact resistance. Small hammer or other heavy objects can be used to tap the plate, genuine plate is not easy to crack, cracking, only slight dents or deformation; Counterfeit products may be damaged easily after impact due to material problems. However, attention should be paid to the strength of the test to avoid excessive damage to the plate.
Bending performance: gently bend the plate, the genuine product can bend without breaking to a certain extent, and there is no obvious crease after restoring to the original state; Inferior products may crack or even break when bent.
Flame retardant: polycarbonate itself has a certain flame retardant. Use a lighter to burn the edge of the plate for a short time, the genuine plate will automatically extinguish after leaving the fire source, and the burning part is less, less smoke and light smell; Counterfeit products may burn quickly, producing large amounts of black smoke and a pungent odor. However, pay attention to safety when performing this test, and ventilate in time after testing.
