• Lead fundamental research into TPU / EPU polymer architecture (soft / hard segment ratios, chain extenders, isocyanates) and their effects on optical, thermal, and mechanical performance. Correlate polymer chemistry with durability, weathering resistance, and long-term stability. Establish lab-scale extrusion and film casting protocols for transparent and optical-grade films. Define critical process–performance relationships, including haze, tensile strength, elongation, tear resistance, and environmental durability. Optimize formulation and processing parameters for high clarity, low birefringence, and minimal defects.
• Build and maintain a competitive intelligence database of global TPU chemistries, extrusion processes, and film performance benchmarks.
• Conduct accelerated aging, optical, and mechanical testing to validate long-term performance targets.
• Translate lab-scale polymer synthesis and extrusion processes to pilot and full production scale.
• Collaborate with process engineers, manufacturing teams, and external partners to ensure successful technology hand-off.
• Identify and protect intellectual property opportunities in TPU / EPU chemistries, extrusion processes, and film applications.
• Stay at the forefront of polyurethane and optical polymer science to drive continuous innovation.
• Provide robust technical solutions to new product development initiatives and lend support to sales and product management teams
• Bridge the gap from bench scale testing to industrial manufacturing processes by taking a lead role in the scale up process
• Develop plans and procedures for specifications & fabrication of components, integration of technologies, balancing cost & manufacturability
• Serve as technical interface to vendors and manufacturers
• Continue to improve upon existing process and product through research and development in the specific area of responsibility
• Remain versed and up to date on polymer chemistry, extrusion and other emerging technologies in the film industry
