Do you really know the operating principle of Reflective Foam Insulation Material?

What is Reflective Foam Insulation?

High Reflective Foam Insulation is the thermal insulation which is made from polyethylene using advanced technology. Its thermal conductivity is a low as 0.30 w/mk. The structure is composed of small closed cells evenly hold tie together which make the foam to have very low permeability.

How Reflective Foam Insulation works?

1. Heat conduction suppression: Thermal insulation materials can reduce heat transfer by reducing heat conduction. Thermal conduction refers to the process of heat transfer in substances, usually through collision and transfer between molecules. Foam insulation materials have a low thermal conductivity, which can inhibit the transfer speed of heat in the material. Its low density and porous structure can make the heat conduction path longer, thereby reducing heat transfer.

2. Radiation reflection: Thermal insulation materials can reduce heat transfer by reflecting thermal radiation. Thermal radiation refers to an object emitting energy to the surroundings in the form of electromagnetic waves, and its heat transfer method does not require the existence of a medium. Foam insulation materials generally have high reflectivity and can reflect most of the thermal radiation energy back to the source, thereby reducing heat loss. The reflective layer on its surface can effectively reflect thermal radiation.

3. Convection blocking: Thermal insulation materials can reduce heat transfer by blocking convective heat transfer. Convection refers to the process of heat transfer through the flow of fluid, usually including natural convection and forced convection. Insulating materials typically have lower thermal conductivity and higher density, which can reduce fluid flow and heat transfer.

Summarize:

Foam materials have excellent thermal insulation properties and are widely used. With the development of science and technology in the future, the application range of foam materials will be further expanded.
