Product Description

1. Product Introduction

PIR foam VFOAM-01 is a rigid insulation material, produced through the reaction of isocyanate and polyether. It has better fire resistance performance than polyurethane foam. In addition, PIR foam has low thermal conductivity, wide service temperature range, and excellent dimension stability properties. It can be cut into a pipe cover and flat or board easily. PIR foam insulation meets the standards of ASTM C591 and CINI 2.7.01.

3. Product Application
It is a kind of ideal organic thermal insulation materials applied at low temperature, result from its low thermal conductivity, lightweight, anti-vibration and compatibility. It is widely used as insulation in  oil refinery,  chemical,  ethylene  and  fertilizer  industries,  as well  as
refrigeration house and LNG systems.


4. Packing and Storage
(1) Store in a dry, lightproof, shady, and ventilated place, keep away from heat source and
protect from sun exposure.
(2) Inner Packing: Polythene bags
Outer Packing: Cartons


5. Application and 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.
