The Applied Technical Services Family of Companies (FoC) uses the ASTM E1545 testing standard to evaluate the glass transition temperature of materials.
What is a Material’s Glass Transition Temperature?
A material’s glass transition temperature (Tg) is the temperature at which the material changes from a glassy and hard state to a leathery and soft state. Tg provides important insight into a material’s strength and overall ability to function as intended when exposed to temperatures and environments. In addition to strength, glass transitions reveal information about various other mechanical properties, including:
- Impact resistance
- Modulus of elasticity
- Operational temperature
What is ASTM E1545?
The American Society for Testing and Materials (ASTM) developed ASTM E1545 as the standardized testing procedure for technicians using thermomechanical analysis (TMA) to determine a material’s glass transition temperature. During the test method, experts subject a sample to controlled heat as they measure the sample’s dimensional changes as it warms. Following the dimensional changes, experts analyze the change in the sample’s thermal expansion coefficient which enables them to identify its Tg.
Our ASTM E1545 Testing Services
Our laboratory provides glass transition temperature testing services that follow processes outlined in ASTM E1545. Upon completion of our testing, our clients have a more informed understanding of their sample’s performance and behavior under specific conditions. Our services are especially beneficial to businesses that rely heavily on the performance of polymers and plastics.
Why is It Important to Test Glass Transition Temperature?
The glass transition temperature is an important property in polymer materials. Understanding how Tg impacts a material’s electrical, thermal, and mechanical properties can be invaluable in material selection and design processes. Tg is adept at predicting the performance of products, which can provide manufacturers an opportunity to optimize their processes to extend a product’s service life.
