Evaluation of biomass plastics by TG-FTIR

TA-2039: Evaluation of biomass plastics by TG-FTIR



Plastics made from plant-derived (biomass), so-called “biomass plastics”, have almost the same composition and physical properties as petroleum-derived plastics, and biomass-derived resins containing a certain percentage of biomass are used as products. It is also generally believed that biomass plastics and petroleum-derived products can be distinguished only by the abundance of C14, which is the isotope of C13. In this study, biomass plastic made of polyethylene used in shopping bags on the market and high-density polyethylene used as a reagent that does not contain biomass were compared and measured by TG-FTIR and evaluated.

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.
