Why does the silicone sleeve on the surface of the water cup appear sticky and powdery after a period of use?

Editor recently saw some comments mentioning the problem of silicone sleeves for water cups when visiting some e-commerce platforms.Some water cups were purchased and used, but they found that the silicone sleeve on the outside of the water cup began to become sticky or powdered. What is the reason for this?

Please forgive me for my habit of visiting peer shops often, especially watching the comment area.Because some customers' replies made people laugh at it, it shows that these customers who sell water cups really don't understand the product or the properties of the material.

The editor will first copy the reply information of some water cup shop customers for everyone to see:

"This is normal and will not affect use"

"Boil it in high temperature water, boil it for a while and then let it dry"

"Rinse and rub repeatedly with detergent, then wash off"

"Dear, did you stick glue or other sticky substances on the silicone sleeve? Usually these things don't happen."

"Dear, we support 7 days no reason to return the goods, if it does not exceed this time, you can return it"

"Dear, if you don't feel good about the silicone sleeve, just throw it away. The silicone sleeve is a gift from us, and the water cup is very good."

Seeing such a reply, the editor wanted to say that if a consumer is a layman, he will be deceived by a store posing as an expert.The phenomenon that the silicone sleeve is sticky and powdery is caused by the following conditions:

First of all, the material is shoddy.Most of the stickiness or powder drop is caused by the use of recycled materials or the use of inferior silicone materials in the material.

Secondly, the production management is not done well.It is not produced according to the production standards required by the specification, including production temperature requirements, time requirements, etc.Some factories have reduced production standards, shortened production time and increased production capacity due to the tight delivery time of orders.

Finally, the consumer's use time does exceed the service life of the silicone sleeve, which is easy to understand.

The editor believes that there is another possibility, but it is very rare, which is caused by the environment where consumers use silica gel. The place with high acidity and high humidity will accelerate the change of silica gel and cause the phenomenon of stickiness and powder loss.
