Basic characteristics of rubber wheels

Basic characteristics of rubber wheels

1. When a rubber product is molded, it is pressed by a large pressure, and the cohesive force of the elastomer cannot be eliminated. When the molding is released, it often produces extremely unstable shrinkage (the shrinkage rate of rubber varies due to different types of rubber. ), it takes a period of time to stabilize. Therefore, at the beginning of the design of a rubber product, regardless of the formula or the mold, it is necessary to carefully calculate the coordination. If not, it is easy to produce unstable product dimensions, resulting in low product quality.

2. Rubber is a hot-melt thermosetting elastomer, while plastic is hot-melting and cold-setting.

Due to the different types of sulfides, the temperature range for molding and curing of rubber is also quite different, and it 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. If not, there may be differences in product quality.
