Problems solved by technology

However, it is often overlooked that inorganic materials such as glass fibers have high production costs, are harmful to the human body, cannot be biodegraded, and cause a huge burden on the human living environment.
At the same time, the cost of inorganic materials is high, so the cost of the vacuum insulation panels made is relatively high, which also limits the application of vacuum insulation panels in various industrial fields
