Response of mat conditions and flakeboard properties to steam- injection variables
… flakeboard. Two resins, phenol formaldehyde and polymeric MDI, were used. Steam-injection press schedules varied from low steam input to high steam input by adjusting steam pressure, steam time, and the density range for steam-injection during press closing. Steam-injection rapidly raises mat …

Relationship of moulding pressure and weigh of granulate in improving the mechanical and characteristics of biopolymer from renewable resources
… isocyanate type Polymethane Polyphenyl (Modify polymeric-MDI) and further processed into granulate (powder) to be able to hot compress by hot compression moulding technique. These fabricated samples were namely as biopolymer. The conversion process of bio-monomer into BP was examined using …

Structural Determination of Copolymers from the Cross-catalyzed Reactions of Phenol-formaldehyde and Polymeric Methylenediphenyl Diisocyanate
… by the cross- catalyzed reactions of PF and pMDI prepolymers. The electronic behavior of phenolic monomers as perturbed by alkali metal hydroxides in an aqueous environment was studied with 1H and 13C NMR. Changes in electronic structure and thus reactivity were related to solvated ionic …
