The difference between pu wheel and rubber wheel

1. Different in nature

1. Rubber wheel: The rubber wheel is a ring-shaped elastic rubber wheel product that is assembled on various vehicles or machinery and is grounded and rolled.

2. Pu wheels: wheels made of PU.

Two, the characteristics are different

1. Features of rubber wheels:

(1) When the rubber product is molded, the cohesion of the elastomer cannot be eliminated after high pressure suppression. When the rubber product is separated from the mold, the shrinkage rate of the elastomer is very unstable (the shrinkage rate of the rubber varies depending on the type of rubber). The elastomer must slowly stabilize after a period of time.

Therefore, at the beginning of the design of rubber products, whether it is a formula or a mold, the degree of fit must be carefully calculated. Otherwise, the product size will be unstable and the product quality will be very low.

(2) Rubber is a hot melt thermosetting elastomer, while plastic is hot melt and cold setting. The temperature range of rubber molding and vulcanization varies greatly depending on the main types of sulfides, and may even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be adjusted appropriately at any time. Otherwise, product quality may vary.

2. Features of pu wheel: elasticity can play a certain shock absorption effect (even better than that of inflatable wheel), good grip, not easy to slip, more wear-resistant, and good comfort performance.
