Low-temperature thermal insulation paper
Application：
Liquid-nitrogen biological container, large storage low temperature tank, low temperature engineering.
The product is a new type of low temperature thermal insulation material produced with special technology and used in insulation container which is hypothermia, cryogenic, high vacuum and multi-layer. It is the fourth-generation product of low temperature thermal insulation paper researched and developed by our company and used in liquid nitrogen container. It was awarded with the prize of state-level new product. Compared with the third-generation product, the product reduced the evaporation of liquid nitrogen, increased the preservation days of liquid nitrogen biological container, extend the service life of liquid nitrogen tank and be accepted and used by domestic manufacturers of liquid nitrogen.
