Product Description

High Temperature PIR Polyurethane Foam Board Low Thermal Conductivity Fire Retardant B1 for Heat Pipe

Product Description

High Temperature PIR Polyurethane Foam Board is a rigid polyisocyanurate panel developed for industrial duty where moderate heat and fire safety matter.

Its isocyanurate structure gives the board a wide service range to +150°C, well above standard PUR foam, while short excursions to 180°C are tolerated.

A low thermal conductivity of about 0.023 W/(m·K) limits heat loss from hot pipes, ducts and vessels, improving plant energy efficiency.

A closed-cell content above 95% and a B1 fire rating make the board moisture resistant and self-extinguishing for safer, longer-lasting insulation.

Typical applications include heat pipes, flue and duct insulation, solar hot water systems, process vessels and industrial thermal plant.

Product Features

Cryogenic High-Temperature Resistant – Wide service range to +150°C handles moderate-heat industrial duty.

Low Thermal Conductivity – About 0.023 W/(m·K) reduces heat loss from pipes and plant.

Fire Retardant B1 Grade – B1 self-extinguishing foam improves fire safety on hot lines.

Closed-Cell Waterproof – Above 95% closed cells resist moisture and vapour ingress.

Thermally Stable – PIR structure resists heat aging and keeps performance over time.
