What conditions are required for the storage of polyurethane foam materials

     Polyurethane foam is a polymer made of isocyanate and polyether as main raw materials, mixed by special equipment under the action of foaming agent, catalyst, flame retardant and other auxiliaries, and foamed by high-pressure spraying on site. There are two kinds of polyurethane foam: soft foam and hard foam. The soft bubble has an open cell structure, the hard bubble has a closed cell structure, and the soft bubble is divided into two kinds: crust and non-crust. The main function of polyurethane soft foam is cushioning. Polyurethane soft foam is commonly used in sofa furniture, pillows, cushions, toys, clothing and soundproof linings. Polyurethane rigid foam body is a new type of synthetic material with thermal insulation and waterproof function, its thermal conductivity is low, only 0.022 ~ 0.033W/ (m* Κ), equivalent to half of the extruded board, is the lowest thermal conductivity of all thermal insulation materials. Rigid polyurethane foam is mainly used in building external wall insulation, roof waterproof and insulation integration, cold storage thermal insulation, pipeline thermal insulation materials, building panels, refrigerated trucks and cold storage thermal insulation materials.

Polyurethane foam insulation board storage method：

Polyurethane foam mold to prevent rust, polyurethane mold is mostly made of metal, in storage to be placed in a dry position to prevent rain and snow soaking, polyurethane foam mold after soaking will corrode the surface smoothness.

Polyurethane foam should be stored indoors when necessary to have a cushion to store, polyurethane tube shell should be in a fireproof dry position, polyurethane foam tube shell will change color under the sunlight, but will not affect the use effect, polyurethane foam has its advantages, in the roof waterproof insulation board, cold storage insulation, pipe insulation materials are widely used.

During the processing of polyurethane foam insulation materials, the use of equipment should be implemented under constant temperature conditions to ensure quality requirements. The foaming process should be 25 degrees for the appropriate temperature, the uniform density of foaming is easy to grasp, so that the finished product insulation effect is good, the cost will be reduced, the foam density of insulation materials - generally in 42kg/m3 thermal conductivity lowest.
