Abstract
The invention relates to a method of producing a new and novel gel composition suitable for use in breast prostheses, including a mixture of hydroxyl terminated polybutadiene resin, diundecyl phthalate, polymethylene polyphenyl isocyanate, and dibutyltin dilaurate catalyst, allowing the mixture to stand, and curing the mixture.
Claims2
A method of producing a gel suitable for use in breast prostheses, comprising:
- forming a mixture of, by weight percent, 9.9% hydroxyl terminated polybutadiene resin and 89.1% 1,2-benzenedicarboxylic acid, diundecyl ester, 0.9% polymethylene polyphenyl isocyanate and 0.1% dibutyltin dilaurate catalyst;
- allowing the mixture to stand for about 16 hours;
- and
- curing the mixture at least two hours at a temperature of 93.degree. C. (200.degree. F.).
A gel suitable for use in breast prostheses consisting essentially of, by weight percent, 9.9% hydroxyl terminated polybutadiene resin, 89.1% 1,2-benzenedicarboxylic acid diundecyl ester, 0.9% polymethylene polyphenyl isocyanate, and 0.1% dibutyltin dilaurate catalyst wherein the components are thoroughly mixed, allowed to stand for about 16 hours and cured for at least two hours at a temperature of 93.degree. C. (200.degree. F.) thereby resulting in a gel having, after 24 hours, a recording of about 180 on the precision penetrometer.
