Analysis of Insulated BoxClassic

first floorPFBoard: Made mainly of high-performance nitrile rubber and polyvinyl chloride, with good insulation effect. Not absorbent, long service life,

Use Health and Safety;It is both an insulation layer and a moisture-proof layer.

second floorEPSPlate: It is made of expandable polystyrene beads containing volatile liquid foaming agents, which are heated and pre molded in a mold

A white object with micro closed cell structural characteristics, mainly used for insulation of composite boards, with excellent and durable insulation properties, and unique buffering

Seismic resistance, aging resistance, water resistance, and good flame retardancy.

Third layer Metal reflective layer: It has good smoothness and thermal reflectivity, maintains a constant temperature inside the box, and protects the water meter from being easily cooled. Make the interior of the watch box

Not only can it maintain a constant temperature, but it also has an aesthetic effect.

The minimum temperature can reach-8℃ non freezing meter
