What is the thermal insulation performance of pearl cotton?
EPE is a foam material made from polyethylene, so named because it looks and feels like a pearl. In addition to having good cushioning and protective properties, pearl cotton also has certain thermal insulation properties. This article will introduce the thermal insulation properties of pearl cotton and its application in detail.
First, the principle of insulation of pearl cotton.
The insulation principle of EPE is mainly based on its unique internal structure and material properties. EPE is made up of many tiny bubbles that can effectively block the flow of air and reduce the transfer of heat. In addition, the material of EPE has a certain reflectivity, which can effectively reflect heat radiation and reduce heat loss.
Second, the thermal insulation performance parameters of pearl cotton.
1.Thermal conductivity.
Thermal conductivity is an important parameter to measure the thermal insulation performance of materials. EPE has a low thermal conductivity, which means it is able to effectively block the transfer of heat and keep the temperature stable. Specifically, the thermal conductivity of pearl cotton is generally 003 W m·k is about 03 w·k, which is lower than traditional insulation materials such as glass fiber, mineral wool, etc.
2.Density and thickness.
The density and thickness of EPE will also affect its thermal insulation performance. Generally speaking, the higher the density and thicker the thickness of pearl cotton, the better its thermal insulation performance. However, the increase in density and thickness also leads to an increase in cost, so it needs to be considered comprehensively in practical applications.
3. Application scenarios of pearl cotton.
Because pearl cotton has good thermal insulation performance and cushioning protection performance, it is widely used in various fields. The following are the main application scenarios of pearl cotton:
1.Insulated packaging.
Pearl cotton quilt is widely used in the field of thermal insulation packaging. For example, in cold chain transportation, the use of pearl cotton as a packaging material can effectively maintain the temperature of the item and reduce temperature fluctuations. In addition, pearl cotton has also been widely used in thermal insulation packaging in food, medicine and other fields.
2.Construction industry.
In the construction industry, pearl cotton is also used as an insulation material. It can effectively reduce the heat loss of the building and improve the thermal insulation performance of the building. At the same time, pearl cotton is also used as a sound insulation material because it has a certain sound insulation effect.
