Expert Details
Plastics and Bio Based Resins, Extrusion Compounding, and Reactive Extrusion.
ID: 727629
West Virginia, USA
Have Specialized in Twin Screw Extruder Compounding and Reactive Extrusion Process Development from bench scale to world class production facilities including Toll Manufacturing. Process Control, Feed systems including preblending, Screw Design, and isolation of the compounded product are integral to this.
As a consultant for a Venture Capital Company, he has scaled up a complex Compounding Process including a Reactive Operation form a bench scale through OEM Vendor Trials to four commercial toll manufacturing lines.Scoped, Designed, worked with Bids, and supported start-up of a Bench Scale Leistritz TSE Research Facility at WVU.

Responsibilities:Principal Engineer, Compounding Technology for nine years.Internal Consultant. Mentor young professionals. Training programs and presentations (to Professionals, Technicians). Process trouble shooting. Global involvement (Japan, South America, China, Australia, Europe. 20 years in Compounding Process Development. 32 years Total Process Development Experience. Process Development research was for new and existing products and/or processes. Chemical Engineering Sciences applied. Worked closely with Product Developers to assure the same or improved performance in the end application. A recent project entailed conception through development through startup and operator training of a novel process for the reduction of VOC emissions that allowed the installation of a major compounding expansion without having to attempt re-permitting with the EPA for increased emissions. Research/development projects range from monomers to compounding including: Styrene/Ethylbenzene Separation. Processes for the manufacturing of Fire Retardant Additives. Emulsion Polymerization. Suspension Polymerization. Solution Polymerization. Isolation of Polymers form Emulsions and Solutions. Drying including Spray, Flash, Fluid Bed, and Rotary Dryers. Compounding of New Polymers and Alloys. Impact Modified SAN PC/ABS PBT/ABS Nylon/ABS PPE/PS&HIPS (At Borg-Warner before the GE takeover.) Vendor Trials. Process Specifications for New Facilities.
