How to select a Resin for specific use ? |
The selection of a resin for a specific use is based on criteria for that application; for example permeability at the use temperature may be a critical requirement and may override other features such as chemical resistance and tensile strength. In each case the choice of material is made by comparing the key property requirements and, of course, cost. The chemical resistance properties of PTFE are so broad that its use is not only restricted to a limited list of chemicals. PTFE is generally acceptable for a wide variety of industrial and commercial applications. Due to lack of additives and extreme chemical inertness these materials also qualify for ultrapure applications, such as using deionized (DI) water in the semiconductor, biological and pharmaceutical industries. |
