Polyisocyanurate (PIR) is an advanced organic polymer thermal insulation material manufactured from isocyanate and polyether as primary raw materials. Combined with catalysts, fireproofing agents, and eco-friendly foaming agents, this foam polymer is produced through precise formulation and controlled processing conditions.

Key characteristics of PIR foam include:

• Closed-cell structure with high obturator rate for superior insulation
• Fine, uniform cell structure for optimal thermal performance
• Excellent flame resistance and retardant properties
• Superior water resistance and moisture permeability
• High compressive strength and dimensional stability
• Chemical stability and excellent anti-aging properties

This high-performance material is ideal for thermal insulation in cryogenic and general cooling environments, with an operational temperature range of -196°C to 120°C.
