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.
- 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.
