Polyurethane refers to a class of polymers composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, electrical potting compounds, and fibers such as
Bivariate Distribution Analysis by CFC - Polymer Char
WebA new novel fabrication method for lensed-fiber has been proposed utilizing UV-curable fluorinated acrylate polymer. The structure is composed of three segments; single mode fiber, coreless fiber and polymer lens-tip. Flexible control of the curvature-radius of lens-tip was realized using the polymer surface tension and free space interconnection … WebHigh resolution cross-fractionation of Polyolefins has been made possible through the new Polymer Char’s CFC fully automated instrument. Two-dimensional distribution relating … how are organic molecules formed
