I have 48 years of experience, and specialize in the field of thermoplastic compounds with specific knowledge in the areas of acrylonitrile butadiene styrene (ABS) plastics and blends and engineering plastics, thermoplastic compounding and melt processing and application development. I have published on such topics as polymeric modifiers for polyvinyl chloride (PVC) performance, high speed testing to describe impact performance of thermoplastics and testing to predict thermoforming condition for thermoplastics.
