High Density Polyisocyanurate Pipe Support/Block HDPIR

1、Product Introduction

Pipe support/block belongs to cold insulation system.In addition to good insulation performance, it shall bear loads from pipe/equipment. 

For different use, ZES has different pipe support/block categories as below:

v  Sliding support

v  Guide Support (including guide support for vertical pipe)

v  Limit/fixing support

v  Insulation block 

 

2、  Properties

(1) HDPIR properties:

The performance of cold insulation pipe support/block depends on the properties of HDPIR.

HDPIR is a kind of foaming polymer, with the features of plastic, rubber and cork. The raw materials are isocyanate, polyether, foaming agent, catalyst, flame retardant, etc. After high speed stirring, materials react and foam to cellular structure product, composed of millions of tiny and uniform sealed cells. It provide benefits of low density, low thermal conductivity, low water absorption. The performance is better than timber.
