Explanation of lifespan prediction! Estimating oxidation induction time (OIT) from CL strength data under heating conditions.
This document is a technical note explaining the determination of OIT (Oxidation Induction Time) and lifespan prediction based on chemiluminescence data of polypropylene powder. OIT can be measured by maintaining isothermal conditions in an inert atmosphere and then switching to an air atmosphere for actual measurement. We introduce a measurement and analysis method for determining OIT from the heating measurement data in an air atmosphere. Please feel free to download and take a look. 【Published Data (Excerpt)】 ■ CL intensity curves from heating data at heating rates of 2.5 to 10 K/min ■ Peak integration of 2.5 K/min-CL data from 80°C to 165°C with slope correction ■ Reaction rate curves for a temperature range of 2.5 K/min with a maximum of 165°C ■ CL intensity curves from heating data at heating rates of 2.5 to 10 K/min ■ Reaction rate curves for a temperature range of 10 K/min with a maximum of 203°C *For more details, please download the PDF or feel free to contact us.

Company information
Our company works in the field of thermal safety evaluation to prevent thermal runaway accidents involving chemical substances. To achieve this, we analyze reaction kinetics parameters from thermal measurement data of a few milligrams of chemical substances and provide a measurement and analysis system that enables thermal safety evaluation when the chemical substances are scaled up to kg to 1000 kg. Additionally, we offer an evaluation system that combines isothermal microcalorimeters (IMC) for lithium-ion batteries and DSC with AKTS analysis software, allowing for comprehensive measurement of the entire battery.
