Thermal behavior of biodegradable plastic straw by sample observation STA

TA-1028: Thermal behavior of biodegradable plastic straw by sample observation STA



Recently, due to the increased environmental problems brought by the use of petroleum-based plastics, research and development efforts for the production and use of biodegradable polymers have recently increased. Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) is one of the common sources of biodegradable polymers which is produced thru fermentation by microorganisms that uses plant oils as raw material. PHBH is a member of the PHA family. Here, we measured the thermal behavior of a biodegradable straw made of PHBH using the sample observation STA.

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.
