Studied, published, and lectured on numerous polymers such as polyethylene (PE), PP, polyvinyl chloride (PVC), polyvinylidene chloride (PVdC), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polystyrene (PS), polycarbonate (PC), fluoropolymers such as Teflon, PFA, PVdF, and PCTFE.
Developed a Paper - Like Film from an R&D concept to respond to a need for an environmentally friendly packaging film.
R&T's Business Unit Liaison to Specialty Films Business and key technologist for Packaging Resins Business.
Led Emerging Technologies to improve moisture and oxygen gas barrier of plastic films by modified metalization and other coatings such as SiOx / AlOx via plasma enhanced chemical vapor deposition (PECVD) and E-beam vaporization.
Continuously solved problems related to plastic films such as dimensional stability, optical properties, adhesive / cohesive failure, occurrence of gel defects, and bubble instability during blown film process.
Demonstrated expertise in thermal, mechanical, and rheological barrier properties of materials.
Pioneering work on nylons (PA6, PA66, PA46, PA12, and amorphous nylons).
Invented and commercialized new applications of additives and lubricants.
Successfully solved manufacturing problems occurring during injection molding, blow molding, thermoforming, cast and blown film operations.
