Following the upsurge of the world cup, many consumers of silica gel souvenirs have asked such a question on various silica gel social forums, "why does my silica gel product deform and stretch back and forth and then it won't play?" This problem also puzzles many friends. At present, in addition to silicone bracelets, there are also many silicone products with this phenomenon. After stretching, there is no rebound, but there is a fog pattern! So what is the truth of this reason?

For processing, many people know that processing in each industry is to catch up with the production of silicone rubber products, so the processing time has become the main factor that this product will not deform and soften, while the silicone bracelet, which is relatively thin in thickness, will soften too early in the process of high-temperature vulcanization, so many silicone factories Home in the processing did not take into account the time can not be arbitrarily reduced, and in the case of production capacity to reduce the time of the product out of the mold resulting in the phenomenon of the product is not ripe!

Secondly, it is the reason of raw materials and vulcanizer. Sometimes, due to the error of formula modulation of silica gel raw materials and different mixing methods, the tensile rebound strength of products is not enough, resulting in the non rebound phenomenon of products with large formula deviation of raw materials. Secondly, it is the good or bad fixed telephone effect of vulcanizer, whether the vulcanizer is even when mixing with rubber, whether the proportion is symmetrical and so on All elements may be related to the tensile resilience of the product!

The above several main reasons are that the deformation and stretching of silica gel products will not take up the main cause, the product will be soft and other adverse factors, while in addition to silica gel bracelets, products with thin thickness and thin strip products will have similar phenomena!
