Permeability of thermoplastic polyurethanes for aviation kerosene storage tanks

Abstract

The permeability of thermoplastic polyurethanes of various grades for aviation kerosene is investigated. A model is proposed for predicting the decrease in fuel mass at different temperatures and the duration of storage in tanks. The composition of the used thermoplastic polyurethanes has a minor effect on the duration of tightness preservation, but it determines the rate of reduction of the fuel mass in the diffusion cell.
