Polymer Consulting Group (PCG) is a premier boutique laboratory and technical service provider located in the Texas Brazos Valley in Bryan, TX. PCG provides laboratory testing, consulting, and scientific expert witness services covering a broad spectrum of physical material characterization and processing technologies. Since its founding in 2003, PCG has rendered technical consulting services to dozens of clients in the polymer scientific community from industry as well as academia. As the premiere service provider in the field of polymer melt extensional rheology characterization and analysis, we offer a one-of-a-kind expertise in understanding the role of rheology in polymer processing and manufacturing-related issues and melt instabilities.  

As a preeminent physical testing laboratory capable of standardized as well as custom material testing methods and protocols, we often handle customer projects that require innovative and unconventional approaches to physical testing which large conventional testing facilities simply can't offer. As a result, we routinely develop new material testing protocols, fixturing and novel laboratory-scale material processing apparatus for our customers that require out-of-the-box solutions. Quite frankly, customers usually come to us when they are confronted with particularly challenging polymer processing and/or materials-related product performance problems, and to date, we haven't faced a customer challenge we haven't been able to resolve.  

In addition to the testing and consulting services that we offer to our industrial and academic customers, PCG provides technical support and expert witness services to the scientific legal community both domestically and abroad. PCG also offers technical seminars and training sessions to industrial and academic customers in the fields of rheology and physical material characterization techniques.

Dr. Martin L. Sentmanat is President and Chief Consultant of Polymer Consulting Group, LTD Co. Dr. Sentmanat received his B.S. (1990) in Mechanical Engineering from Texas A&M University in College Station, TX, and then headed north to Montreal, Canada where he received his Masters (1992) and Ph.D. (1995) in Chemical Engineering from McGill University under the supervision of Prof. John M. Dealy. In 1995, Dr. Sentmanat began working as a Senior Research Physicist at The Goodyear Tire & Rubber Company at Corporate Research in Akron, OH, and after authoring more than two dozen worldwide patents left Goodyear at the end of 2003 to help found Xpansion Instruments, exclusive manufacturer of his breakthrough invention, the SER Universal Testing Platform. Since its introduction in 2003, the SER has revolutionized the field of experimental extensional rheology and redefined the paradigm in miniature-scale materials testing. Having authored numerous technical journal articles and presented scores of lectures and seminars domestically and abroad, Dr. Sentmanat is a globally recognized expert in the fields of rheology, physical material characterization and polymer processing.
