High Purity PTFE Molding

APT's Clean Molding Room Minimizes The Introduction Of Impurities During Teflon™ PTFE Compression Molding

APT's clean molding room is utilized when the highest PTFE purity level is required for demanding scientific & industrial applications. Our clean procedures along with clean garbed molding technicians keep impurities out of our molded stock.

While our everyday PTFE clean molding standards strive to minimize processing introduced impurities, such as carbon based contaminants, the facilities shown here allow us to offer you a higher level of clean. Should you have particular demands, we can work with you to define the clean protocols that will be implemented during the molding of your order.

APT's involvement with High Energy Physics projects such as EXO, a particle physics experiment looking for neutrinoless double beta decay, gave us an opportunity to establish clean processing procedures that met their demand for an ultra low background material. Our ultimate goal - to maintain a purity level that is very near to that of the raw material.

In the case of PTFE compression molding, the first step in the defense against dirty stock is to start with a clean PTFE resin and keep it that way. One such very clean resin is Chemours' (formerly DuPont) NXT grade of modified Teflon® PTFE. This resin has been tested and known to have low intrinsic concentrations of radioactive impurities.
