The effect of formulation on the physical properties and durability of flexible PVC geomembranes

摘要

This paper summarizes work performed in the laboratory and in actual field conditions. Flexible PVC is composed of avariety of ingredients and there are many ways of formulating to achieve the same initial physical results. The objective was todetermine how the choice of the ingredients used in a flexible PVC formulation could determine the functionality and thus, the longtermperformance as a flexible geomembrane. The data proves that the ingredient type and in some cases the amount, affect endperformance significantly.If the proper physical properties are specified and tested only well formulated flexible PVC geomembranes will pass and thus the typeof formulation does not have to be specified.
