Recent Advances in the Development of Rigid Polyurethane Foams of Improved Thermal Insulation Efficiency

Autor: A. Cunningham, G. M. F. Jeffs, I. D. Rosbotham, D. J. Sparrow

Publikováno v: Journal of Thermal Insulation. 12:209-222

The fundamental mechanisms of heat transfer through rigid polyure thane (PUR) foam are reviewed in terms of three distinct elements, λ g, λ s and λ r, which represent heat transfer by thermal conductivity through the gas phase, solid phase and by

Publikováno v: Fire and Materials. 10:79-89

A two-storey test rig was used to investigate how an insulated facade would react to the impingement of a simulated room fire. In particular, whether or not a facade insulated with polyurethane foam would promote vertical flame spread. Wooden cribs w

Molecular Weight Calibration in Steric Exclusion Chromatography of Diblock Copolymers of Polystyrene and Poly (Ethylene Oxide)

Autor: M. J. Guest, G. M. F. Jeffs, J. V. Dawkins

Publikováno v: Journal of Liquid Chromatography. 7:1739-1751

The molecular weight calibration curve in steric exclusion chromatography of a diblock copolymer of polystyrene and poly (ethylene oxide) is obtained by a method involving the universal calibration principle. The method is developed from the experime
