PIR cold storage panel characteristics :
1. Thermosetting material, flame retardant grade
2. Low heat conductivity, good thermal insulation effect, wide range of usage.
3. It has the characteristics of fluorine-free, environmental protection, anti-corrosion, mildew resistant and so on.
4. High mechanical strength, dimensional stability and durability.
5. CNC cutting can meet the requirements of different thickness of cold insulation.

PIR is a kind of foam plastic containing isocyanate ring in the molecular structure. Compared with PUR, PIR has the following advantages:
(1) It has good heat resistance. It can be used continuously for a long time at 150 ℃, and the size change rate is less than 1%. If for short-term usage, temperature can be higher. If PUR is used for a long time at this temperature, the strength will obviously decrease, and the appearance and size will also change.
(2) Flame resistance penetration is good. PIR panel with thickness of 250mm is burned with propane flame to the center of one side, it takes around 30min burn the panel. The high density PIR and the inorganic filler material have longer flame duration and can even burn several hours.  is burned in a few minutes under the same conditions.
