Description
This unit covers the skills and knowledge required to choose polymer materials for an application for a new product or advanced process or product problem-solving.This unit applies to a senior technician working alone or as part of a team.The unit principally refers to the application of in-depth knowledge of materials, process, equipment and problem-solving to identify polymer structures and properties; determine possible modifications to polymer properties; select tests and interpret results; and select the materials for an application.No licensing or certification requirements apply to this unit competency at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
Notes
Elements and Performance Criteria
1. Identify polymer properties based on polymer type
  • 1.1 Estimate molecular weight distribution changes with polymerisation mechanisms and conditions applied
  • 1.2 Predict impact of monomer and polymer structure on polymer properties
2. Estimate polymer properties based on polymer structure
  • 2.1 Predict property changes caused by polarity and intermolecular forces
  • 2.2 Determine possible polymer properties based on chain flexibility variations caused by changes in regularity, tacticity and intermolecular forces
  • 2.3 Estimate polymer properties based on molecular weight or molecular weight distribution and degree of cross-linking
  • 2.4 Predict barrier properties based on molecular orientation and degree of crystallisation
3. Choose a polymer compound for an application
  • 3.1 Select appropriate base polymer or polymers for application based on the polymer properties
  • 3.2 Determine reinforcements or additives required to meet product specification
  • 3.3 Predict failure mechanism for selected compound and modify selection as required
  • 3.4 Determine need for polymer compatibilisers and specify appropriate use as required
  • 3.5 Develop formulation and select appropriate production methods that meet job specifications
4. Organise testing of polymer and interpret test results
  • 4.1 Select appropriate test or tests for compounded polymer based on test purpose and limitations and material being tested
  • 4.2 Test colour using colour coordinates as required to meet product specification
  • 4.3 Interpret test results and modify formulation or production method as required to meet product specification
