Glass fiber paper
Product Classification:
Product Description
Glass fiber paper is a kind of industrial paper, generally used as filter materials, sound-absorbing materials, heat insulation materials, electrical insulation materials, etc. It is made of 99.99 glass fiber (diameter below 0.3-0.5um), lightly beaten and copied with chemical materials. When glass fiber paper is used as a thermal insulation material in a vacuum multilayer thermal insulation structure of a storage and transportation container for cryogenic liquids (such as liquid helium, liquid hydrogen, LNG, liquid oxygen, liquid nitrogen, liquid argon, etc.), it is generally referred to as a cryogenic thermal insulation material or a vacuum multilayer thermal insulation material.

Application areas
The glass fiber elastic felt has excellent thermal insulation properties, which can effectively reduce the heat transfer between the inside and outside of the storage tank and help maintain the low temperature environment inside the storage tank. Glass fiber elastic felt is an important part of cryogenic insulation system of LNG storage tank. It is located between the inner tank wall plate and the expanded perlite, and is used to absorb the lateral pressure of the expanded perlite on the inner tank under various working conditions (pre-cooling contraction of the inner tank, hydraulic expansion of LNG operation, expansion of the inner tank during emptying and maintenance). This design maintains the integrity of the tank and prevents damage to the inner tank wall panels. The glass fiber elastic felt is suitable for heat preservation and cold preservation of various storage tanks and equipment.
Glass fiber elastic felt can still maintain good mechanical properties and stable chemical properties at high temperature. Therefore, it is widely used in petrochemical, metallurgical furnaces, electric power industry and other high temperature equipment insulation. It is also used in the insulation of industrial pipes to reduce heat loss and improve energy efficiency.
Glass fiber mat is used in the automobile industry to manufacture automobile shells, interiors and seats. It can improve the strength and rigidity of automobiles, reduce weight, and improve the absorption effect of noise and vibration. In addition, it can repair damaged ship hulls and extend the use. life.
Application of glass fiber paper in the construction field: glass fiber paper has excellent sound absorption and sound insulation properties, and is widely used in the construction field. The subsequent processing of glass fiber paper, such as: multi-layer composite can be used as a building filling material.
Electrical industry: glass fiber elastic felt is used to manufacture insulation materials for cables, motors, transformers and other electrical equipment, with good insulation performance and high temperature resistance.
