The sealing effect of the plastic water cup, is rubber coating or silica gel better?

Today, the editor participated in a video conference for product seminars with customers in Singapore.At the meeting, our company's engineers gave reasonable and professional suggestions for the products that customers will develop.One of the problems that caught the editor’s attention was that for the effect of sealing the water in the cup, is it better to seal the water rubber coating or to seal the water with a silicone seal?


There is a concept in this, rubber coating.What is rubber coating?The rubber coating is a secondary process on the original material, and another material is covered with soft rubber.The main function of rubber coating is to increase the feel of the product and increase the friction of the product.The rubber coating can play the role of sealing the water in the cup.


I won’t introduce the sealing function of the silicone ring too much. This function can be said to be encountered every day in daily life.At present, most of the sealing parts of daily necessities on the market use silica gel.Both silica gel and rubber coating can play the role of sealing water, so which method will be better for sealing water?


Through this international video conference, I learned a lot and understood the difference between the two.Under the same reasonable use environment, both can play a good role in sealing water, but silica gel is more durable and easier to produce, and silica gel is safer and healthier.


The longer it is used at any time, the more times it will be used. Silica gel can also have great stability in water sealing function, but soft glue will not work.Soft rubber has a short life span and relatively short durability.At the same time, during production, rubber coating has strict requirements on the structure of the product, and the production cost is relatively high.


When the water temperature is too high or the water cup encounters backlog deformation, the sealing water of the silica gel remains stable, and the rubber coating will become serious and cause the water cup to leak.So in general, compared to encapsulation and silica gel, the sealing water of silica gel is better.
