System introduction：
     DUOWEI PUR products adopt internationally most advanced six-component online automatic cooperation mixed pouring technology in raw material proportioning and process output, through which six-component continuous foaming is realized for the first time in China, and mixing and proportioning process can be realized online at a time; moreover, formula can be adjusted according to the environment change to make raw material mixing more even and foam smoother by cooperating with aerating and mixing device, thereby producing high strength, energy-saving and environmental protection building boards.

    POILISOCYANURATE, abbreviated as PIR; composite boards developed by DUOWEI use excessive sulfone isocyanurate, so ring structure of chemical compound and higher sulfone isocyanurate index form the dense PIR, thereby making interior rigid foam more stable and have high heat resistance and flame resistance. Experiment shows that the bubble can endure 200 ℃ in a short time and can endure 160℃ in a long time.

Product features:
Concave-convex groove structure, improving tight insulation at board joints, especially designed for refrigerating chamber and storage

Boards are even, firm and stable, and have good thermal insulation performance and waterproof performance

Light weight and elegant appearance, effectively solving temperature difference of cold storage industry

The storage can freely change in three directions of length, width and height, and also can expand or narrow as necessary within certain modulus; assembled boards can be disconnected and to be installed in different place, installation is simple and rapid
