Thermal insulation solution upgrade for thermos cups
The customer initially used PE foam to make a rectangular single-sided adhesive tape on a 304 stainless steel inner tank. It had defects such as poor thermal conductivity, insufficient sealing, and too rapid temperature decay, making it difficult to achieve the 24-hour ±2°C constant temperature requirement.
We redesigned and developed it in a targeted manner and used ceramic fiber insulation cotton as the insulation layer. Its low thermal conductivity and good flexibility ensure that it fits the inner wall and effectively blocks heat. The outer layer is covered with aluminum foil to create a fully wrapped structure. The aluminum foil tightly seals the interface, significantly improving the sealing performance. After testing, the product temperature is stable at 58 - 62°C for a long time, and the 24-hour temperature attenuation is controlled within - 2°C. It accurately meets customer expectations and provides an excellent technical solution for efficient heat preservation of thermos cups.
