Product Description

 

Product Introduction
Vpipe-2A is a kind of high fire retardant rigid foam blend polyols by 141b base, reacting with  MDI  to  be  rigid  foam,which  is  even  foam  cell,  low thermal insulation,high fire retardant,no shrinkage in low temperature,
widely used in stream heat pipe,LNG, and other low temperature insulation project and so on.
