Latest Patents

One of his latest patents is titled "Process for the preparation of a foam-cored laminate having metal facers." This invention improves adhesion between the skin and core of laminates that utilize rigid polyisocyanurate foam cores. The enhancement is achieved by incorporating a dipolar aprotic organic solvent in minor amounts into the reaction mixture used to prepare the foam core.

Another significant patent is "Polyisocyanurate foams based on esterified DMI oxidation residue additive." This invention describes polyisocyanurate foams characterized by a high degree of fire resistance, low smoke evolution, and high compressive strength. Notably, it also leads to the formation of a protective intumescent char over unburnt foam when subjected to combustion. This combination of features is accomplished by using a minor amount of a polyol mixture prepared through the transesterification of a residue obtained from the manufacture of dimethyl terephthalate.
