Product Description

High Temperature Resistant Polyurethane Foam Board Low Thermal Conductivity Fire Retardant Panel

Product Description

High Temperature Resistant Polyurethane Foam Board is a rigid PIR panel built for hot-duty insulation, with a long term service temperature up to +120 °C and short excursions to +150 °C without losing its closed-cell structure.

The PIR (polyisocyanurate) core is more heat stable than standard PUR, so it resists thermal ageing, shrinkage and powdering far better in hot pipelines, ovens and equipment insulation.

Thermal conductivity stays low at about 0.022 W/(m·K), and the closed-cell content above 95% keeps the board waterproof and vapour tight while it operates at elevated temperature.

An oxygen index of 30% or more gives a self-extinguishing B1 fire rating with low smoke, so the board combines heat resistance with a better reaction to fire than ordinary foam.

A core density of 48–60 kg/m³ gives a compressive strength at 10% deformation of at least 220 kPa, and dimensional stability at –50 °C for 48 h stays within 1.0%, so the board holds its shape through thermal cycling.

The board is designed for surfaces that run hot but stay below +120 °C in continuous service; above that limit the foam can age and shrink, so it must not be used for sustained higher temperature duty.

Typical uses include hot water and steam-adjacent pipework, heat exchangers, ducting, ovens, drying equipment, solar thermal lines and industrial process insulation.

Where the board meets a hot surface, the facing and adhesive must also be rated for the temperature, and a continuous vapour barrier keeps moisture out of the closed-cell core.

The board is cut to size on site and fitted with tightly butted, staggered joints; for outdoor service a metal cladding of galvanized steel or aluminum protects the foam and the vapour barrier.

Product Features

High Temperature Resistant – Long term service up to +120 °C, short time to +150 °C.

Fire Retardant B1 – Oxygen index ≥ 30%, self-extinguishing, low smoke.

Low Thermal Conductivity – About 0.022 W/(m·K) at service temperature.

Closed-Cell Waterproof – Closed cells above 95% keep the hot-duty core dry.

Dimensionally Stable – Dimensional stability within 1.0% at –50 °C for 48 h.
