Whether the foam silicone tube will absorb water vapor

First of all, we start with the foam silicone tube composition, it is composed of silicone and blowing agent, it is the same principle as steaming steamed bread, so that everyone can easily understand. Secondly, it is divided into closed cell foam and large cell foam, foam density is not the same, the effect of foam silicone tube is like a sponge, so it is usually called sponge silicone tube.
We all know that sponges have adsorption capacity, so the foam silicone tube we produce also has the same function of absorbing water vapor. Therefore, the daily use of foamed silicone tubes is to maintain a dry environment, and the common use is the sealing of lamps.
