SYNTHESIS OF RIGID POLYURETHANE AND EFFECT OF SILICON SURFACTANT ON ITS

PROPERTIES

igid polyurethane foam has been synthesized from high functional crude MDI and blending poly-l for a

wide range of surfactant concentration with R141b blowing agent. Cream time, gel time and take free time

increase as the concentration of surfactant is increases. The foam density decrease as the concentration of

surfactant is increases the decrease in density due to the increase blowing efficiency with surfactant. Surface

tension also rapidly decreases in accordance with cell size decrease and close cell content rapidly increase at

low surfactant concentration. The decrease of cell size was accompanied by the decrease of thermal conduc-

tivity. Today, numerous building blocks and polymer structures are available to chemists and engineers for the

synthesis of polyurethanes by the poly-addition principle. Because the manufacturer of polyurethane articles

converts low-molecular weight raw materials into finished polymers at the production site, author have place

special emphasis on the brief history and some basic concepts about the raw materials and chemistry of poly-

urethane. He also covers the manufacturing techniques and processing equipment’s in this research article,

reviews physical, chemical, mechanical and electrical properties and also cover the applications of all types of

polyurethanes for a wide range of industries.
