Our High Closed-Cell Polyisocyanurate (PIR) foam is a rigid insulation material formed by the precise polymerization of isocyanate and polyether. The exceptionally high closed-cell content of ≥95% creates a structure of isolated cells, which translates directly into extremely low thermal conductivity, outstanding dimensional stability, and minimal water vapor permeability. With overall performance that surpasses standard polyurethane (PU), it is the ideal choice for demanding industrial applications.
PRODUCT CHARACTERISTICS
Feature

SCOPE OF APPLICATION
It is a kind of ideal organic low-temperature heat insulation materials, which has the advantages of small thermal conductivity and high dimensional stability. It is suitable for a wide range of temperatures and is widely used in LNG, ethylene, cold storage and other low-temperature industries.
Strapping Material : stainless steel tape, sub sensitive tape.
Packing and Storage
1. Store in a dry, lightproof, shady, and ventilated place, keep away from heat source and protect from sun exposure.
2. The inner package is packed in black polyethylene bags and the outer package is packed in cartons.
Cautions
1. PIR shall be handled gently, avoid rolling, collision and heavy pressure during moving.
2. When applied to pipe and equipment insulation, PIR shall be fastened with glass fiber tape or steel band.
3. Cut it with saw during application.
