First of all, there are many reasons for the aging of the silicone protective cover. Although the natural rubber has not been separated when it was first released, it is still necessary to look at the environment and the people and the fields of use. Some friends love themselves. The protective cover is a treasure, it protects the product from harm at all times, and some friends don’t care. It’s not long before it starts to appear aging, so the artificial factor still has to occupy the majority, you have to Always learn to protect and maintain it for long-term use.
On the other hand, consumer friends are not protected in the right way. There are many scenes and environments in use. Although silica gel has outstanding new energy, it can be used for some ozone, humidity, glare, liquid oxygen, etc. It is not a joke, but when it is used for a long time, cracks, discoloration, yellowing, and aging of the oxidation reaction begin to increase, which is one of the factors.
Finally, the material itself has already had problems. Some silicone raw materials contain organotin flow curing agents and reinforcing curing agents. The ratio of blending has a little gap and the effect on fixed-line is not good. Polysulfide polysulfones and Ethyl urethane or amine-containing articles can not be saturated, and the compound reaction occurs after the addition, and the phenomenon of overall non-solidification and incomplete fixation occurs. Therefore, the material of the silica gel product manufacturer has poor fluidity during processing, and the product has a bursting edge and is hard and soft. Different degrees, the phenomenon of tensile rebound is reduced.
