Finding the right formulation that works in a process environment is a challenging task that consumes a lot of time - and sometimes even very expensive production test runs. Lab scale equipment is ideal to minimize the development time to validate and optimize the formulation. This webinar highlights a case study to investigate the right material and the right fill. Learn about an optimized process showcasing an enhanced lab scale compounding setup - including loss in weight feeders - and a novel way of creating test specimen straight out of the compounding process. Brabender chose a sustainable approach with a sawdust filler for a typical wood plastic compound formulation.

Primary Topics:

  • Use of gravimetric feeders for stable and consistent results
  • More formulations in less time to save costs
  • Find the ideal filler fill rate for the best performance and cost
  • Learn about space-efficient full lab scale equipment and possibilities
