encryptionInsulation boxMost of the stored items are taken out of the refrigerator, which does not carry much cooling and energy. Therefore, a matching technology ice is used in the insulation box, making the car insulation box more powerful and useful. This type of technological ice only needs to be frozen in the refrigerator for 12 hours in advance, and then placed with the items in the car insulation box to achieve a long-lasting effect. Some can even be useful for a week.

Encrypted incubator is composed of typical phosphorus nitrogen flame retardant system, which can include ammonium polyphosphate and polycyandiamide. At the initial stage of foam heating, the flame retardant differentiates into phosphoric acid, which forms phosphate ester with flame retardant effect with polyhydroxy compounds and releases water vapor to vaporize the flame retardant in the foam at high temperature to produce incombustible gas, so that the molten foam is carbonized to form a loose porous flame retardant layer.
