Abstract : Large differences in termite resistance of the various polymers were observed. Several physical modifications of PVC such as surface smoothness, increased thickness, and incorporation of mineral fillers, provided modest to considerable improvement in resistance to various termite species. Increasing hardness from 10 to 30 (Shore D DUROMETER SCALE) reduced the number of PVC FAILURES BY 86%. The highest overall performance for flexible materials was obtained with EPR and chlorosulfonated polyethylene. They offer the advantages of being innocuous to man and the environment and the promise of very long service life without loss of effectiveness. (Author, modified-PL)
