Proprietary CFC-Free  PU compounding technology

High pressure in-line compound feeding system

Two key reasons behind Huayu's quality of products

• excellent uniformity in insulating property in production run   
• excellent adhesion with foams and various facing materials
• excellent dimensional stability ,
• less brittleness etc  ,

    All these are the common problems associated with the conversion from the older Freon based PU compound to CFC-free PU compound .

2.  Production facilities :  Huayu’s continuous composite board production line is fully automated with excellent quality control and process improvement features . The production line was imported from Europe and is the only line in China using such sophisticated system . Several advanced production improvement technologies are used ,  like the

• high pressure in-line compound mixing system to ensure uniformity in foam size  ,
• comb-sprayer system  to ensure uniform density of foam throughout  ,
• double roll precision conveyor press system to ensure uniform thickness etc .

The finished composite boards are comparable in quality with products from any advanced factory in the world and are  superior to other China made equivalents  .                   Go Top
