How can the thermal insulation performance of a plastic kit be determined?

Plastic kits, also known as foam incubators or foam storage boxes, are so called primarily because they offer excellent thermal insulation. However, the insulating performance of these kits can vary in strength. How can one assess the thermal insulation effectiveness of a plastic kit?

　　 Plastic kit Also known as a foam incubator or foam storage box, it derives its name from the insulating properties of its plastic components. However, the thermal insulation performance of these plastic components can vary in strength. How can one assess the insulation effectiveness of such plastic components?

　　1. Plastic containers both preserve freshness and provide excellent thermal insulation. The duration of heat retention depends on the density and thickness of the plastic container, as well as ambient temperature and the tightness of the outer packaging.

　　2. The plastic casing has a wall thickness of 2 cm; a plastic casing with a density of 20 typically maintains its insulating performance for 18–24 hours in typical seasons, and approximately 36–72 hours during winter.

　　3. If the plastic packaging is thick and tightly sealed, the insulation effect will last even longer. Wrapping the package around the food will significantly enhance its insulating performance, though this benefit is most noticeable during the summer months.

　　The thermal insulation performance of a plastic kit can be assessed by its foaming rate. Poor foaming results in inferior insulation, whereas good foaming indicates strong thermal insulation. The lighter the plastic kit, the better its insulation—though excessively light foam may compromise compressive strength. For optimal thermal performance, the foam must be uniform.

　　If the plastic kit has good sealing performance, there should be no leaks. Place some ice packs inside and close the lid. If there are any gaps, seal them tightly with several layers of clear tape. With enough ice packs, the ingredients can stay fresh for four to five days.

　　Main performance characteristics of the polystyrene plastic kit:

　　(1) The thermal conductivity of polystyrene plastic kits is comparable to that of conventional molded polystyrene. Long-term use does not compromise their insulating performance.

　　(2) Polystyrene plastic, as tested by the National Construction Quality Supervision and Inspection Bureau, exhibits a tensile failure strength of 0.29 MPa perpendicular to the panel surface. Compared with conventional molded polystyrene boards, this board itself possesses higher cohesive strength.

　　(3) Polystyrene plastic is fire‑resistant; AEPS insulation boards are made from inorganic polymeric materials, and their manufacturing process meets the A2‑grade (homogeneous) standard.

　　(4) The construction process for polystyrene plastic kits is identical to that of conventional molded polystyrene boards. It is easy to handle, simple to install, shortens the construction schedule, and results in low material consumption.

　　(5) The polystyrene plastic insulation system has passed the weathering resistance test conducted by the National Construction Quality Supervision and Inspection Agency, with all performance indicators exceeding the requirements of the national standard.

　　(6) Compared with other insulation materials, polystyrene plastic—specifically AEPS insulation boards—has a lower thermal conductivity. Under the same energy-saving requirements, it can be installed at a thinner thickness and does not necessitate additional safety measures, thereby reducing construction costs for real estate developers and property owners.
