Yichang foam box is produced with high-quality foam materials, and part of the product space is replaced by gas. Each cubic meter contains millions of independent closed bubbles. The overall volume is much larger than plastic; the heat insulation and sound insulation effects are good. Thermal conductivity is the weighted average of the ratio of the thermal conductivity of pure expandable polystyrene raw materials to air (54:45). In terms of sound insulation, there are two ways, which are to absorb sound energy, reduce reflection and transmission, and eliminate resonance and noise; anti-aging and anti-corrosion.
Foam box will not have obvious aging phenomenon unless it is exposed to high energy radiation for a long time. It can withstand the corrosion of many chemical substances, such as enoic acid, dilute alkali, methanol, lime, etc .; good antistatic performance .
