Polyurethane foam production

In conclusion, I have attempted to demonstrate that bark can be used as the sole polyol component in the production of rigid polyurethane foam. These foams possess good physical as well as inherent fire retardant properties. With the availability of bark as a reactive polyol, I can see a means of utilizing bark as a cheap raw material in producing economical polyurethane foam products.

Phosphorus-containing reactive flame-retardants are mainly phosphonates or phosphates with hydrogen atoms which can be substituted by hydrocarbon groups, so that they are capable of bonding to molecules of the matrix polymer. A notable example is the series of phosphorus-containing polyols. Their alcoholic hydroxyl groups are involved in a polyaddition reaction of the polyurethane foam production. 

A specific polyurethane foam product was developed by Recticel under the trade name Firend for protecting upholstery and matresses. It can be applied as a separate layer between the cover and the foam.
