With a total of three patents to his name, Schmitz is known for pioneering processes that enhance the flame resistance and insulation properties of these materials.

Latest Patents

Schmitz's latest patents include a groundbreaking process for the production of rigid polyurethane foams. This process involves reacting a polyisocyanate with a polyester that contains at least two isocyanate-reactive hydrogen atoms, alongside a carefully selected combination of water, organic blowing agents, flameproofing agents, and crosslinking agents. The specific quantities recommended—15 to 35 parts by weight of polyester, 50 to 80 parts by weight of flameproofing agent, and 5 to 15 parts of crosslinking agent—result in foams that provide excellent insulation in applications requiring flame resistance.

Another significant patent addresses the production of rigid foams containing both urethane and isocyanurate groups. This innovative process utilizes a polyisocyanate and a compound with multiple isocyanate-reactive hydrogen atoms, combined in the presence of an aqueous solution of alkali metal carboxylate. The use of alkali metal acetates, such as potassium acetate, in concentrations between 10% to 50% by weight ensures that the resulting foams possess outstanding insulating properties.
