Pir Polyisocyanurate

Description:

ROCKAL Polyisocyanurate (PIR) Pipe insulation is a CFC Free rigid closed-cell, high-performance insulation for pipe, cold, cryogenic, vessel, equipment and duct applications. ROCKAL offers complete range of pipe insulation products in a selection of densities and compressive strengths. ROCKAL Polyisocyanurate-rate insulation features one of the lowest ambient k-factors among all pipe insulations of <0.023 W/m. k @ mean temperature of 10 ºC (0.159 BTU · in/hr. · ft2 · ºF at 50 ºF and can be used for the temperature range from -183 ºC to 149 ºC (-297 ºF to +300 ºF).

Application:

⦁ROCKAL Polyisocyanurate (PIR) Insulation materials has many diverse applications in HVAC System, Oil,     Gas, Petrochemical, Process Plant, Cryogenic and General Insulation Industries.
⦁  It can be used for Pipe, Slab, Vessel, Tank, Equipment Insulation and Thermal Support Inserts.
⦁  The insulation are comply with factory fabrication standard of ASTM C 450 and ASTM C 585.

Key features:

⦁    Very good flame spread/smoke developed performance with class 1 (Class A) rating according to ASTM E-84 and BS 476 part 6 & 7. 
⦁    Closed-cell and non-fibrous structure.
