  • Method of producing polyurethane foams for low stress encapsulation
    Patent number: 4696776
    Abstract: A method for encapsulating electronic components in high acceleration and high thermal cycling environments. A liquid uncured thermal setting polyurethane formulation is mixed with a finely ground particulate foam which serves as a nucleating agent. The mixture is in accordance with the polyurethane formulation. The resultant foam contains open air pockets which allow it to be compressed and then re-expand.
