Predictive analysis of OIT values using heating measurement data up to 190℃!
This document is a technical note explaining the OIT prediction based on Chemiluminescence data for polyamide 6 powder (without added antioxidants). Using heating measurement data up to 190°C (35°C below the melting point), where PA6 is in a state of slight melting of crystalline and amorphous parts, the OIT value is predicted. It was found that the oxidation induction time (OIT) can be predicted in the range of 90°C to 230°C from the heating measurement data at 0.2, 0.4, and 0.8 K/min. For details, please refer to the published catalog. 【Published Data (Excerpt)】 ■ CL strength signal data from 50 to 250°C (0.8 K/min) ■ Selection of appropriate peak integration range ■ Standardization of CL strength curves at 0.2 to 0.8 K/min with a peak integration value of 8.28E8 cts/g ■ Peak integration curve of heating rate 0.8 K/min data ■ CL strength curve log-log plot when the peak integration value is set to 8.28E+8 cts/g *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.
