RE: Independent Chemical Testing of PP, PVDF and CPVC Special Waste Piping Systems When CPVC special waste piping systems was first introduced to the market, skepticism arose concerning the material's ability to safely convey an array of discharged chemistries from laboratory facilities. As a result, Battery Design LLC has commissioned an independent testing of PP, PVDF, and CPVC special waste piping systems to visually measure their integrity when conveying certain waste streams of chemistries; which are commonly used in various laboratory applications. Following, is a copy of the final report of this test. Thank you. Terence Zhao EPS Product Manager
