Why the silicone pad is non-durable？

 1) It is not because of the liquid silicon rubber itself, but the process of filtering.

 The filtering is not handled properly and impurities are not all filtered out;

 or in the process of packing, the containers are not cleaned thoroughly.

 2) The amount of silicon oil. More silicon oil added, softer the pad printing will be, meanwhile nondurable and easy ageing it will also turn to be.

 3) Some customers do not know well about the performance of silicon rubber. Actually, the durability of printing pad is closely related to the size of printing pattern. Some factories do not want to take the trouble to change the printing pad. While in fact, for large pattern, large silicone pads should be used, otherwise, use small one.(Generally, the ratio of the silicone pad and printing pattern is 3:1)
