Course Title: Plastic Material Additives

8 Professional Development Hours/0.8 CEUs

Course Description: Additives may be examined from many perspectives; the approach taken in this course will examine the main purpose for using the additive, broadly separated into processing aids, property modifiers and protective materials. Also discussed is information about the additives that are blended with polymers to improve the balance of properties and optimize the polymer for specific applications.

Overall Course Objectives:

Learn about the different types of additives and how they affect polymer properties and processing.
Identify the major additives groups.
Understand what these additives are used for in modifying the polymer properties and processing.

Course Content:

Lesson 1 - Introduction, Antioxidants

Objectives:

Recognize types of flame retardants and how they are incorporated into plastics.

Understand the use of impact modifiers and the advantages of adding them to plastics.

Compare the uses of internal lubricants to external lubricants, and identify common
lubricant groups.

Lesson 3 - Plasticizers, Coupling Agents, Light Stabilizers

Objectives:

Identify the factors to be considered when choosing a plasticizer for an application.

Develop an understanding of coupling agents functionalities.

Recognize three types of light stabilizers used in polymer systems, and explain the most common method of evaluating UV absorbers.
