Expert offers over 20 years experience working with polymer applications for microelectronics and most recently compounding and mixing rubber compounds for sidewall,inner liner,body-ply skim,Nylon Skim,and abrasion.
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

Marketing Experience
Developed value presentation where data mined patents directed to electrically conducting polymer applications and showed the intersection to companies development roadmap
Developed Pentacene cluster of patents directed OLED application and developed value presentation-Sold for $2M.
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.
