The PU Foam wheel is made of polyurethane, which has a greater load-bearing capacity than rubber. These won't puncture or go flat and are resistant to corrosion and wear. The sawtooth tread pattern provides traction. This wheel is intended for use in professional and industrial environments.
1.Solid urethane foam wheel will never go flat.
2.Good for any terrain or uneven surface.
3.Resistant to water, oil, dirt, acid, and alkali.
