Polyisocyanurate Foam (PIR)
PIR is a foam material made from the reaction between isocyanate and polyether under catalysis. Its physical and fire-resistant properties are superior to those of regular polyurethane. It is an ideal organic low-temperature thermal insulation material with a low thermal conductivity, lightweight, shock-absorbing, and adaptable. It is widely used in refineries, chemical plants, ethylene production, fertilizer plants, cold storage, and the construction industry for insulation and thermal protection.
