GFRP Sandwich Panel For Refrigerator Truck

Product Introduction

Refrigerator Truck

The heat insulation materials used in refrigerated vehicles are mainly polyurethane foam and extruded polystyrene foam, when manufacturing refrigerated trucks, how to choose between polyurethane insulation board and polystyrene insulation board?

1. Combustion basis

Rigid foam polyurethane is a thermosetting material, which forms a carbonization layer after heating and combustion, blocking the further entry of heat and oxygen, and hindering the further combustion of foam body, which is not easy to produce fire spread accidents. And polystyrene foam is a thermoplastic material, which shrinks and melts when heated, and then drops and burns. It cannot produce a carbonization barrier layer, and it is easy to produce flame spread and flashover accidents.

2. Corrosion resistance

Polyurethane is resistant to water, oil and solvent. Polystyrene water resistance but not solvent resistance, benzene, ester solvents are extremely sensitive, easy to produce rapid corrosion.

3. Different application modes

Polystyrene foam can only be molded and extruded into the factory state of foam forming, and hard foam polyurethane can be sprayed, poured and factory foaming forming, so the application method, application field are more diverse than polystyrene foam, convenient.
