Over the last three decades, the rubber process analyzer has evolved as the processability test instrument of choice for measuring and solving many rubber factory problems.

To better understand the damage endured by mechanisms during downhole simulation testing (rapid gas decompression testing, or RGD testing), three downhole formulations (FKM, HNBR and NBR) were evaluated.

The world is changing around us and synchronous belt technology is changing with it. In both our business and personal lives, we are expecting more of the machines we operate.

This paper will study the effects of multiple repurposed raw materials for reinforcement in a standard carbon black based thermoset rubber formulation. The materials will be: carbon black as the standard; pyrolysis carbon black (recovered); ground tire rubber (both ambient and cryogenic; and styrene butadiene elastomer manufactured and processed by EFG Polymers L.L.C. from ground tires as a starting point and chemically treated for regeneration.

There are several different classes of organic peroxides used in crosslinking HNBR. Understanding these peroxides and how co-agents interact with them is an important consideration when developing optimized compounds.
