Glass fiber low-temperature insulation paper

Dingri paper is our high-performance low-temperature insulation series product. This type of material is made of ultrafine glass fibers and has the high-quality and uniform fiber distribution unique to wet laying technology.

This lightweight spacing material is a highly cost-effective choice for achieving super insulation. They are usually combined with metal foil to form a multi-layer structure, and then placed between the inner and outer walls of the low-temperature container. This series of products includes flame retardant low-temperature paper (a type of adhesive free micro glass fiber paper suitable for containers/pipelines such as liquid oxygen/liquefied natural gas/liquid hydrogen) and non flame retardant low-temperature paper (a polyester product suitable for liquid nitrogen/liquid helium containers/pipelines, etc.).
