High performance vacuum insulation board is used as the core insulation layer and traditional rigid foam polyurethane is used as the protective insulation layer to form the composite board. Polypropylene foam as the outer insulation box, insert six composite boards to form a combined PU+VIP insulation box.                                                                                                                                                                                                                                           

1. Excellent insulation performance: vacuum insulation board as the core insulation layer, the insulation time can reach more than 96 hours. Under the condition of 48 liters volume, the heat preservation time can reach 109 hours at 2-8℃. When the product is heat preservation, it is equipped with 5℃ cold storage agent ice board.                                                                                                                                                                           

2. Small size, light weight, impact resistance, beautiful appearance, not easy to dirty.                                                                                                                                                

3. The insulation box is made of environment-friendly and pollution-free materials.
