Following the trend of the World Cup, many consumers in silicone souvenirs have raised the question on various silicone social forums, "Why does my silicone product deform and stop bouncing after stretching back and forth!" This question has also puzzled many friends, and currently, in addition to silicone bracelets, there are also many silicone products that have this phenomenon. Instead of bouncing back after stretching, they show foggy patterns! So what is the truth behind this reason?



For processing, many people know that every industry requires a rush to produce silicone rubber products, and the processing time is no exception. Therefore, the processing time has become the main factor for the deformation and non elasticity of this product. For silicone wristbands, which are relatively thin, if the molding time is too early during high-temperature vulcanization, the product will definitely become soft. Therefore, many silicone manufacturers did not consider that the time cannot be reduced casually during processing, and reduced the molding time of the product in order to meet production capacity, resulting in the product becoming soft and immature!

Secondly, there are reasons related to the raw materials and vulcanizers. Sometimes, due to errors in the formulation of silicone raw materials and different mixing methods, the tensile rebound strength of the product is insufficient, resulting in large deviations in the raw material formulation and non rebound of the product. Secondly, the fixing effect of the vulcanizing agent is good or bad, and factors such as whether the vulcanizing agent is evenly mixed with the rubber material, whether the proportion is symmetrical, etc. may all affect the tensile rebound performance of the product!

The main reasons for the deformation, stretching, and non elasticity of silicone products mentioned above, as well as the softening of the products, are mainly due to these factors. In addition to silicone wristbands, thinner products and thin strip products can also experience similar phenomena!
