Product Description

PH Value 5.5-7 Polyiso Insulation Board Cold Insulation Material For Industrial Pipe

Kaff Rees provides professional insulation solutions from -196℃ to +400℃, specializing in R&D, production and distribution of insulation materials and pipe support systems. Our complete product portfolio covers all support situations, operational loads, and temperature ranges for industrial insulation systems in petrochemical, coal chemical, LNG, low temperature, cold air, subway, and underground moisture applications.

Polyisocyanurate (PIR) is a foaming material made by polymerization of isocyanate and polyether, offering superior physical and fire resistance properties compared to polyurethane. With excellent thermal conductivity and dimensional stability, it's classified as an organic hard thermal insulation material.

Key Features

Fire resistance rated as B1
Operating temperature range: -196℃ to 120℃

Applications

As an ideal organic low-temperature heat insulation material with excellent thermal conductivity and dimensional stability, PIR is widely used in LNG, ethylene, cold storage and other low-temperature industries across a broad temperature range.

Typical PIR Insulation System Structure

PIR Shell: inner layer + middle layer (if necessary) + outer layer
Secondary Vapor Barrier: PAP aluminum foil
Main Vapor Barrier: mastic + fiberglass meshes + mastic
Metal Protective Layer: aluminum alloy plate, stainless steel plate, aluminized steel plate, GRP
Sealant: HS-10-02, Foster 95-50, etc
Strapping Material: stainless steel tape, sub sensitive tape

Packing and Storage

Store in a dry, lightproof, shady, and ventilated place, away from heat sources and protected from sun exposure
Inner package: black polyethylene bags; Outer package: cartons

Handling Cautions

Handle PIR gently, avoiding rolling, collision and heavy pressure during movement
When applied to pipe and equipment insulation, fasten with glass fiber tape or steel band
Use saw for cutting during application
