PVC and rubber conveyor belts can both operate in wet environments, but moisture alone should not determine the purchase. This guide helps plant procurement teams compare belt materials, define washdown and operating conditions, qualify a PVC conveyor belt supplier, verify samples and documentation, and normalize RFQs before bulk ordering. It also explains when light-duty PVC construction is a logical starting point and when mechanical load, abrasion, impact, or tension makes rubber the more appropriate direction.
