First silica gel protective sleeve aging reason very much, although the early stage of the natural rubber just out of the mold products did not tell the don't, but in the later still want to see the use of environment and the use and the use of field, some friends loved his case as it is a treasure, time to protect the product from damage, while some friends don't care. Dilly here where dilly dilly will not be long to begin to appear aging, so the human factor or to occupy the majority, you can always learn to protect maintenance can be used for a long time.

On the other hand is the protection of the consumer friends way wrong, there are a lot of scenarios and environment are in use, and silica gel, although there is a prominent all sorts of new energy, but for some ozone, humidity, light, oxygen and other place is no laughing matter, and linger for a long time to use appears cracks, discoloration, appear yellowing phenomenon, gradually began to appear oxidation accelerated ageing, That's part of the human factor.

Finally is the material itself has problems, some silicone material in the raw material of organic tin liquid curing agent and reinforcing agent conflict, allocation proportion is a little gap edge to fixed-line, polysulfone polysulfide compounds containing amine content and ethyl carbamate or items not saturated, add after the combination reaction, There is the phenomenon of overall non-curing and fixed phone incomplete, so the material silicone product manufacturers appear poor liquidity in the process of processing, the product has burst edge, the hardness and softness are different, and the tensile rebound is reduced.
