Pu foam is one of the new synthetic material with most rapid development and extensive application in modern plastic industry.It is featured that,by altering the chain configuration in its molecule,its character can be changed to a large extent.By altering the ingredient,foams of different density and capability can be obtained,from soft to rigid.With its convenience in onsite shaping,spay and painting and other features like small specific gravity,high intensity,low heat conduction coefficient and high insulation,it is being extensively applied in all industries. Currently,its application can be found in the heat insulation,heat preservation,shockproof,sound insulation and light framework for petrol pipe,fridge,ice-cabinet,deepfreeze,aviation,architecture,building decoration,shipbuilding,and aotu manufacturing.Generally speaking,PU foam is playing a significant role in the global plastic industry.
