3 Terms and definitions

The following terms and definitions defined in GB/T 4132 apply to this document.

3.1 Vacuum insulation panel;VIP

A thermal insulation product in which the core material is encapsulated with a gas barrier film in a vacuum state.

Note. In order to maintain the vacuum inside the product, getter and/or desiccant can be added.

3.2 Center-of-panelthermalconductivity

The apparent thermal conductivity of the central area affected by the edge of the gas barrier film is not considered.

3.3 Corematerial

Used in vacuum insulation panels, it is made of one or more materials such as fiber, powder, foam material, etc., which has a certain support and heat preservation effect s material.

3.4 Barrierfilm

It is composed of multiple layers of high molecular polymer and/or metal film, which can block the penetration and diffusion of gas or water vapor in the surrounding environment

Inside the vacuum insulation board, it is a thin film material that maintains the inside of the vacuum insulation board in the expected vacuum state for a long time and provides mechanical protection.

Note. The bag made of gas barrier membrane for packaging core material is called gas barrier membrane bag.
