1. When rubber products are formed, after high pressure pressing, they can not be eliminated due to the cohesion of the elastomer, and when forming and leaving the mold, it often produces extremely unstable shrinkage (the shrinkage rate of rubber varies due to different rubber species), and it must be stabilized after a period of time. Therefore, at the beginning of the design of a rubber product, regardless of the formula or mold, it is necessary to carefully calculate and match, if not, it is easy to produce product size instability, resulting in low product quality.
2. Rubber is a hot-melt thermosetting elastomer, while plastic is hot-melt cold-set. Due to the different types of sulfides, the temperature range of rubber molding and curing is also quite different, and it can even be affected by climate changes, indoor temperature and humidity. Therefore, the production conditions of rubber products need to be moderately adjusted at any time, and if not, there may be differences in the quality of the products.
3. The rubber and plastic nine-longitudinal closed bubble structure can effectively prevent heat conduction.
