EPE / XPE Foam Insulation With Thermal Insulation Function

- Aug 01, 2017-

Foam packaging, is made of foam made of the packaging is made of polystyrene (EPS) raw materials through the mold by the heat processing made of the package known as the bubble in the case of high load,EPE / XPE foam insulation through the deformation, energy dissipation energy And so on to achieve the role of cushioning shock absorption. At the same time with thermal insulation function. EPS is generally white.

1. Light weight: EPS packaging products part of the space for the gas replaced by the cubic meter per cubic meter contains 300-600 million independent air bubbles, because it is several times the size of other plastic to several times.

2. With the ability to absorb the impact load.When the foam products are impacted,EPE / XPE foam insulation the gas in the foam through the stagnation and compression, so that the external energy is consumed, dissipated, foam gas with a small negative acceleration, to protect the role.

3. Thermal conductivity is good. Thermal conductivity is the weighted average of pure EPS thermal conductivity (108 cal / mh degrees) and air thermal conductivity (90 cal / mh degrees).

4. Sound insulation performance .EPS product noise mainly through two ways, one is to absorb acoustic energy, reduce reflection and transmission; the second is to eliminate resonance, reduce noise.

5 anti-aging, anti-corrosion performance. In addition to prolonged exposure to high energy radiation, the product no significant aging phenomenon. Can withstand many chemical substances, such as dilute acid, dilute alkali lime, asphalt.

6. Anti-static performance. As the EPS products with low conductivity,EPE / XPE foam insulation so easy to frictional products in the phenomenon of their own products, the general user products will not be affected, for high sperm electronic products, especially modern large-scale integrated block structure Components, should use anti-static EPS.

Foam packaging construction measures are different, the insulation performance depends mainly on the envelope of the heat transfer coefficient or heat transfer resistance of the size of the use of insulation materials and envelope glass insulation board roof together. Directly with the composite wall of its heat transfer coefficient is smaller heat transfer resistance, its better insulation performance. Evaluation of different indicators, thermal insulation properties are usually used to determine the value of heat transfer coefficient or heat transfer. Insulation refers to the summer heat transfer process is usually 24 hours for the cycle of periodic heat transfer to consider. Insulation performance is usually evaluated by the maximum temperature of the inner surface of the envelope under outdoor outdoor temperature conditions. Foam Packaging If the maximum temperature of its inner surface is below or equal to the maximum temperature of the inner surface of a brick wall under the same conditions, it is considered to meet the insulation requirements. The use of materials that reflect solar radiation and the envelope structure,EPE / XPE foam insulation the roof together with the indoor surface to maintain the appropriate temperature to achieve the purpose of insulation. Different heat transfer processes, foam packaging insulation means that the heat transfer process in winter is usually considered to be stable heat transfer to consider some of the effects of unstable heat transfer.
