Rules for evaluation and completion of the course
Attendance in lectures is recommended. Attendance in exercises is compulsory. The attendance to the seminar is regularly checked and the participation in the lesson is recorded. Absence may be in justified cases compensated for by the agreement with the teacher via working out a special programme.
Aims
The subject "Plastics Processing Technology " provides students with basic information describing the structure of plastics and their properties from the point of view of physics, rheology and processing. Also dealt with are the essential processes and basic applications in various areas of life and industry.
