THE EFFECT OF PROCESSING CONDITIONS ON THE PHYSICAL PROPERTIES OF SEVERAL POLYURETHANES

Abstract

Experiments were performed, following statistical procedure, to determine the effect of changes in processing conditions on the physical properties of five experimental polyurethanes. Changes in polymer raw materials had more effect on polymer properties than changes in processing parameters, such as curing time, curing temperature, mixing time, and catalyst-addition temperature. Polymer properties, such as gelation time, hard ness, and proportional-limit elongation, are more sensitive to changes in processing than other polymer properties, such as tensile strength and polymer-to-metal bond strength. Statistical analysis of variance permitted the effects of two-factor interactions to be estimated.
