Expert in Rubber Mixing, Formulation, Testing and Chemical Analysis Especially High Natural Rubber and Butyl
Expert ID: 732492 Georgia, USA
He has extensive high volume experience optimizing Halo-butyl compounds. I have resurrected techniques to analyze rubber compounds with high Carbon Black filler and am versed in modern FTIR spectral subtraction techniques.
Versed in Rheological measurements to assess quality of rubber compounds after mixing and curing, His expertise includes a understanding of the target mechanical properties green, and in the cured state.
Expert holds six US Patents, four of which are directed to Polyimide and other polymer Microelectronic applications.
Expert can offer spin apply process problem solving.
Expert may consult nationally and internationally, and is also local to the following cities: Augusta, Georgia - Athens, Georgia - Macon, Georgia - Columbia, South Carolina - Greenville, South Carolina

|Other Relevant Experience|
|Optimized polymer to polymer adhesion of polyimide coatings
Modeled permeability as function of Vander Waals Radius of gases to find a gas hermeticity probe that has low solubility and low diffusivity in polyimide
Found reclaim chlorobutyl gave unstable properties and that variability was signaled to by variability in TC90 found over the period in question.I found the evidence in the certificates of analysis of the rubber bales. Latter found stabilizer concentration was not tested nor assured by the process.
Determined by requesting C13 NMR that high concentration Natural Rubber was found in the center of cured lumps found in butyl innerliner compound,
The two polymers do not mix and thus steps Expert took to increase shear rate, reduce scorch of returned material and reduce size of balls of returned material reduces viscous heating in the mixer and thus reduced cured lumps.
