Critical Plastics Performance at Elevated Temperatures

Gain a better understanding of changes to plastics performance properties when exposed to elevated temperatures for an extended period of time.

Understanding the thermal endurance of plastics is one key element in the pre-selection of materials for end-product applications, especially in longer-term, safety-critical applications.

This on-demand webinar reviews what the Relative Temperature Index (RTI) means in a Plastic Material and how it is determined.  The requirements for a Long Term Thermal Aging (LTTA) program and why a plastic material used in an end-product needs an RTI rating are also discussed.

Learning objectives:

  • Understand the critical properties of plastics when exposed to elevated temperatures 
  • When is an Elevated Temperature Rating required?
  • Understand the programs available to establish RTI ratings.
