The rollers are made from a high-quality specialized urethane resin, resulting in a PVA (Polyvinyl Alcohol) structure that offers exceptional absorption properties.
These PVA sponge rollers are highly efficient, capable of absorbing water ranging from 10 to 150 times their own material weight.
Yes, we provide fully customized solutions. Both the diameter and the length of the roller can be adjusted to meet your specific industrial requirements.
The recommended operating temperature range is between 0ºC and 65ºC. The material has a melting point of approximately 180ºC.
The roller is designed to be soft and pliable when in a wet condition, which is ideal for cleaning and dehydration without scratching surfaces. It becomes hard when completely dry.
The product features weak acid and base resistance, making it suitable for various industrial cleaning processes involving mild chemical solutions.
