1. Rubber pads: highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force,       and can return to its original state after removing the external force. Rubber is a completely amorphous polymer, its glass transition temperature (T g) is low, and its           molecular weight is often large, more than several hundred thousand.

2. Rubber is a hot melt thermosetting elastomer, while plastic is hot melt and cold curing. Due to the different types of vulcanizates, the temperature range for molding and      curing of rubber is quite different, and 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, the quality of the products may vary.
