Course Description

Increase the impact resistance of your engineering polymers without compromising on other performance (modulus, yield strength…) by smartly selecting impact modifiers from the existing solutions (copolymers, blends, hard fillers...). 


Chris DeArmitt (20+ years experience) will explain how to prevent loss in transparency & colorability due to impact modifiers using real-life case studies.

Why should you view this course?

Attempts to increase impact resistance often go hand in hand with a loss in transparency, modulus, and other properties. However, this is not always the case! A careful selection of your impact modifiers can help you avoid such compromises. Join this course and:

  1. Better select impact modifiers by understanding the key failure mechanisms (crazing, shear yielding) and critical parameters to improve toughness in your engineering polymers.

  2. Solve compatibility issues between impact modifiers and other additives (fillers, pigments, flame retardants, etc.) by recognizing the causes and preventing them.

  3. Easily tweak final impact resistance by adjusting additives, impact modifier concentration, particle size, inter-particle spacing, etc., depending on your engineering plastics.

Who should join this course?

  • R&D people who need to find the right balance between impact modifiers and other additives (fillers, pigments, flame retardants, etc.) in their engineering plastics.

  • This course is suitable for intermediate level proficiency

Course Outline

The following sections will be covered during this session:

Plastics fundamentals, e.g., mechanical properties

  • Property balance between modulus, strength, and impact resistance
  • Performance / cost ratios for engineering polymers
  • Impact failure mechanisms

Impact modifiers selection

  • Adding fillers, elastomer particles, or making polymer blends...
  • The pros and cons of different elastomer chemistry (polybutadiene versus acrylate rubber)
  • The importance of impact modifier particle size, bonding, and cross-linking

How to minimize unwanted interaction between particulate impact modifiers and fillers/pigments (including real-life cases)

How to minimize the effect of impact modifiers on other properties: transparency and colorability (including real-life cases)
