How to distinguish between PVC conveyor belt and PU conveyor belt?

<p>How to distinguish between PVC conveyor belt and PU conveyor belt? I believe that many customers are not able to distinguish it directly, and some customers will question: Why is the PU conveyor belt that obviously cost several times to buy not durable?</p><p><br></p><p>It is not uncommon for this situation, because the two belts of <a href="https://www.uliflex.com/pvc-belt-conveyor-industrial-waste-sorting-belt-conveyor-for-electronic/package-factory/distributor" rel="noopener noreferrer" target="_blank">PVC conveyor belt </a>and PU conveyor belt are visually similar, but it is relatively difficult to identify for consumers who do not understand this industry. The editor can tell you a simple trick to distinguish these two materials: if you touch these two conveyor belts with your hands, you will find that PU conveyor belts are softer than PVC conveyor belts.</p><p><br></p><p>In response to this situation, the following are some of the better distinguishing techniques so that everyone can better distinguish the two conveyor belt materials:</p><p><br></p><p>1. Elasticity of conveyor belt</p><p><br></p><p>PVC conveyor belt rebounds slowly after folding, <a href="https://www.uliflex.com/uliflex-pu-timing-belt-ceramic-timing-belt-at20-rubber" rel="noopener noreferrer" target="_blank">PU conveyor belt</a> rebounds quickly</p><p><br></p><p>2. Scratch resistance of conveyor belt</p><p><br></p><p>The surface of the conveyor belt is scratched with nails, the surface of the PVC conveyor belt is prone to dents, and the recovery is slower; the PU conveyor belt is basically free of dents</p><p><br></p><p>3. Combustion smoke method</p><p><br></p><p>PU burns less smoke, mainly white smoke, and occasionally there is smoke because of insufficient combustion. PVC burning smoke is big, all is black smoke</p><p><br></p><p>Smell the burning smell</p><p><br></p><p>4. PU is burning. There is a certain scent, and the smell is small, it becomes a black viscous liquid after burning, and it sticks after touching, and there is wire drawing; when PVC burns, the smell is large, and it is very pungent. After burning, it becomes carbonized, harder, and hand twisted Will become powder</p>
