Fluid & Gas Compatibility Testing

Polymers are routinely to a wide variety of fluids and gases in their application environments, and often at elevated temperature and pressure.  Thermo-chemical attack of the polymer/rubber compounds is where it can all start, whether it is swelling, breaking of chemical crosslinks, polymer chain reactions or extraction of plasticizers or antioxidants.

Argen experts have extensive experience in safe and rigorous testing with all manner of fluids and gases relevant to a variety of industries, including under extreme conditions.  Argen is fully equipped to test and qualify polymeric materials, and to study the degradation effects through mechanical and chemical testing. We have successfully completed hundreds of such projects from single pot exposures to comprehensive material qualification programs involving multiple materials, many months of aging at multiple temperatures, and post-aging evaluation by mechanical, thermal, and spectroscopic analysis.  We have performed this type of work for some of the world’s largest oil & gas exploration companies, major integrated service companies, and every position in the materials supply chain from polymer manufacturers to molders to distributors to OEM companies using these materials in their products.  We know the quirks, the pitfalls, and the best ways to most directly get the information you need.

We can perform this type of testing from the simple to the very complex.  From simple dumbbell specimens immersed in a fluid as in ASTM D471, to seals constrained in glands as in API 17D Level II testing, to specimens aged under mechanical loads while immersed in a fluid.  From standard to full custom, we have the expertise and the facilities to get the job done quickly, safely, and correctly.
