Evolved gas analysis of polyacetal

TA-2027: Evolved gas analysis of polyacetal


Polyoxymethylene(POM) also known as polyacetal is an all-purpose engineering plastics with excellent mechanical properties. Due to its durability, it is used as a substitute for metal parts mainly used as gears, bearings, various parts. Other uses include stationery and musical instruments such as woodwind and brass instruments. Evolved gas analysis is used to qualitatively confirm the evolved gases as POM is heated.

TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA).



DSC with industry-first self-diagnostic feature and industry's highest temperature range

DSC is a thermal analysis technique that quantifies the amount of energy in a reaction.

Quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature.

DSC8271 is a high-temperature type DSC with a maximum temperature of 1,500°C.

TMA is the measurement of a change in dimension or mechanical property of the sample while it is subjected to a controlled temperature program.


The compact humidity generator (HUM-1) is connected to the TG-DTA for measurements under constant relative humidity water vapor atmosphere.


TMA/HUM measures change in dimension or mechanical property of a sample while subjected to a temperature regime under water vapor atmosphere with a constant relative humidity.

In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change.
