Overview
The Volta Belting RPN-3 NP is a premium polyurethane round belt manufactured by Volta Belting Technology Ltd., a world leader in thermoplastic elastomer (TPE) conveyor belting solutions. This 3.0mm diameter belt comes in 30-meter length and features a smooth finish in green color, making it ideal for packaging, printing, and general light-duty conveying applications. The belt delivers reliable performance across a wide temperature range without stretch or slip.
Key Features
- Profile: Round RPN series designed for smooth operation on grooved pulleys
- Material: Reinforced polyurethane (PU) compound with no-stretch polymer construction
