Diffusion of herbicide in polyethylene

In order to develop a system for protection against blood-sucking mosquitoes and flies, we are looking for diffusion rates and permeation figures, of insecticide / herbicide in several grades of polyethylene. The active chemical has an average of around molar mass of 500 gram / mol. The concentration of the herbicide is 1 weight percent (the herbicide, insecticide is kept in solution by several surfactants, with a concentration of around 4 weight percent), the remainder is water.

Instead of carrying out experiments in a laboratory, we want to know whether you can predict the diffusion, permeation rate and solubility of

-herbicide, insecticide

in polyethyelene (HDPE, MDPE, LDPE, LLDPE), poly vinylchloride (PVC) and epdm rubber (for sealing and joint purposes, EPDM).
