High density (HDPIR) and (HDPU) pipe supports

High density (HDPIR) and (HDPU) pipe supports

Product Overview

The high-density polyisocyanurate pipe support system is composed of isocyanates and polyethers as the main raw materials, as well as foaming agents, catalysts, and fire retardants. It is a foamed polymer with plastic, rubber, and cork characteristics generated by high-speed stirring and mixing reaction. A bubble is composed of thousands of extremely small and uniform independent pores, forming a three-dimensional honeycomb structure. It has high density, low thermal conductivity, low water absorption, and a texture much better than wood. Protective pipe sockets and hangers used in petrochemical bases, liquefied gas fields, refrigeration warehouses, and central air conditioning systems in China and European and American countries.
