Understanding Heat Deflection Temperature (HDT) of Plastics

June 8, 2021

What is HDT?   The Heat Deflection Temperature (HDT), or Heat Distortion Temperature, is a measure of a polymer’s resistance to alteration under a given load at an elevated temperature.  It is also known as the 'deflection temperature under load' (DTUL) or 'heat deflection temperature under load (HDTUL)'.  Basically, it tests the stiffness of a material as the temperature increases.   It is the temperature at which a polymer test...

How Continuous Use Temperature Relates to the Stability of a Machined Polymer

April 27, 2021

The continuous service temperature, or continuous use temperature (CUT), is the maximum ambient service temperature in air that a material can withstand and maintain 50% of its initial physical properties after long-term service.   What is long-term service?  It's defined as 100,000 hours of service – well over 11 years, if used 24 hours a day, 365 days a year.  The continuous use temperature property tells machinists and users what...

MACHINING HYTREL® THERMOPLASTIC ELASTOMER: A PLASTICS GUIDE

April 19, 2021

An Informational Brief on Polymer Machining   Copolyester elastomers (COPE) are high-performance, high-temperature elastomers that have several properties of thermoset rubber with the processing ease of engineering plastics. One of these thermoplastic elastomers (TPC-ET) is DuPont’s HYTREL®. It is known for toughness, tear resistance and good flex fatigue along with good chemical and temperature resistance. For these reasons, it is an excellent general engineering thermoplastic for everyday to mission critical... Read More
