Description
This unit of competency covers the skills and knowledge required to predict polymer properties and characteristics as typically used in problem solving and product and process improvement.This unit of competency applies to technicians or similar roles who are required to predict the impact of process conditions on polymer properties, predict physical properties from polymer morphology, determine the impact of use conditions and polymer characteristics on physical failure, and organise and interpret tests. This unit of competency applies to an operator/technician applying specialised theoretical and technical knowledge and well developed skills in situations that require autonomy, discretion and judgement. The person may work alone or as a member of a team or group and will work in liaison with other shift team members, team leader and supervisor, as appropriate.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1 Predict the impact of processing conditions on polymer properties
  • 1.1 Predict property changes due to molecular weight and temperature
  • 1.2 Identify the glass transition temperature and melting point relative to ambient temperature
  • 1.3 Describe the morphological changes occurring to polymers as the temperature is raised to typical moulding conditions
  • 1.4 Describe the effect of cooling rate on polymer morphology
  • 1.5 Predict potential product dimension/shape changes due to internal stresses resulting from molecular orientation
  • 1.6 Determine the affect of post-mould annealing on the degree of crystallisation and crystal
2 Predict physical properties of polymers from their morphology
  • 2.1 Predict the effects temperature, crystal size, degree of crystallisation, molecular orientation on physical properties
  • 2.2 Predict shrinkage from morphology
3 Determine likely physical failures of polymers
  • 3.1 Determine impact of physical use conditions on physical failure
  • 3.2 Determine impact of polymer characteristics on physical failure
4 Organise and interpret polymer tests
  • 4.1 Describe melt flow properties from flow data
  • 4.2 Choose appropriate test type to measure desired criteria
  • 4.3 Specify relevant standard test method
  • 4.4 Interpret test result, making allowance for possible variations in test
