Polyurethane wheels which produce in Spring and Autumn are excellent PU wheel’s surface is smooth and pretty. It’s reasonable temperature’s range from 5 degree Celsius to 20 degree Celsius.
Why do PU wheels that produce in Summer and Winter is poor surface?
It contain more water in air in Summer, in same time, raw materials of polyurethane wheel also hold more water.
In very cold winter, foam temperature is too low, so foam effect is also poor.
I advise that customers place PU wheel order in Spring and Autumn.
