This hands-on course is designed for the entry-level rubber technician or as a review. The course will familiarize the student with formulation construction, discussion of compounding ingredients, operation of laboratory size mixers and mills, and sample preparation. Testing areas such as rheology, viscosity, physical testing, abrasion, and dynamic properties will also be covered. Safety will be key in all topics.Click to view Course Outline
