Basic Raw Material For Polyurethane



Polyurethane Rigid Foam


Introduction:

Polyurethane rigid foam,is made from reaction of rigid polyether polyol and polymeric MDI.It is mainly used in the insulation of refrigerators,construction,cold storage,spraying,solar energy,heat pipes, etc.

 

Polyether Polyol:                                                                         

Mainly uses sucrose,sorbitol,glycerol,penta erythritol,di glycol,propylene glycol as starter,and synthetized with epoxide,it is the main raw material for the production of rigid polyurethane foam.

We are supplying all kinds of Asia made premium rigid polyol, please contact us for detailed information.

 

Polymeric MDI:

Is a mixture containing a certain proportion of pure MDI and a polyisocyanate. It is used widely in polyurethane rigid foam as main raw material.      

We are supplying all kinds of Asia made premium polymeric MDI, please contact us for detailed information.

 

Blowing Agent:                                                                                

The blowing agent,of polyurethane rigid foam can be water,141B,cyclopentane,HFC-245fc,HFC-365mfc,n-pentane,isopentane,CO2, etc.A new generation of blowing agent as HCFO-1233zd,HFO-1336mmz is to be developed.

Flame Retardant:           

Currently the flame retardant used in polyurethane rigid foam is mainly phosphorus series added flame retardant.If a higher flame retardant grade is required,special flame retardants will be needed in the formula.
