What are the basic characteristics of rubber wheels?
1. When the rubber product is molded, after high pressure suppression, the cohesive force provided by the elastomer cannot be eliminated. When the molding is released, it often produces extremely unstable shrinkage (the shrinkage rate of rubber varies depending on the type of rubber. ), after a period of time, it can be gentle and stable. Therefore, when a rubber product is designed at the beginning, regardless of the formula or mold, it is necessary to carefully calculate the fit. If not, the product size is likely to be unstable and the product quality is low.
2. Rubber is a hot melt and thermosetting elastomer, while plastic is hot melt and cold. Due to the different types of vulcanizates, the temperature range for molding and curing of rubber varies considerably. It may even be affected by climate changes 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.
