Product Description

High Temperature Resistant Polyurethane Foam Board Low Thermal Conductivity Fire Retardant B1 Panel

Product Description

High Temperature Resistant Polyurethane Foam Board is a rigid PUR / PIR closed-cell panel built for service temperatures above the normal range, with the PIR grade taking long-term duty up to about +150 °C.

Its isocyanurate ring linkages give higher thermal stability than standard foam, so the panel keeps a low thermal conductivity of 0.022 W/(m·K) or less and resists ageing, shrinking and powdering under heat.

The closed-cell structure of 95% or more limits water absorption to 4% or below, and the high oxygen index of 30% or more gives a stable B1 fire rating with self-extinguishing, low-smoke behaviour.

A core density of 48–58 kg/m³ provides a compressive strength at 10% deformation of at least 220 kPa, so the panel resists handling and support loads.

The panel is faced with aluminum foil or glass fleece and is installed with a continuous vapor barrier and sealed, staggered joints so moisture cannot reach the hot face or form a thermal bridge.

It is a general high-temperature insulation rather than one fixed duty and is used on hot process pipework, heat supply lines, ovens, ducts and heaters, and other equipment that runs above the usual PUR range.

The product should not be used above its rated service temperature, since prolonged overheating causes the foam to age and shrink, and it should be protected with a jacket in exposed or outdoor service.

Product Features

Cryogenic High-Temperature Resistant – Long-term up to about +150 °C, with higher short-term peaks available.

Low Thermal Conductivity – Thermal conductivity ≤ 0.022 W/(m·K) keeps hot-service heat loss low.

Fire Retardant B1 Grade – Oxygen index ≥ 30% gives a stable, self-extinguishing B1 rating.

Closed-Cell Waterproof – Closed cells ≥ 95% hold water absorption to ≤ 4%.

PUR / PIR Available – PIR for the highest temperature duty, PUR for general service.
