Products Advantages
1. 1. Thermosetting material with high level of combustion retarding.
2. 2. Low thermal conductivity ,excellent cold insulation effects.
3. 3. PIR is the only CFC Free product, designed within the guidelines of the Montreal Protocol, 1987, for the protection of the Ozone layer. ,environment-friendly ,anti-corrosive ,anti-mold and etc.
4. 4. High mechanical strength ,dimensional stability and durable life.
5. With PUF / PIR, insulation thickness can be reduced by 50% compared with cork, 44% compared with expanded polystyrene or fiberglass. It exposes lower surface area, reducing area or expensive vapour ![Description: D:\网站制作\PIR pipe\铝箔贴面资料图.png]()
