We conduct "Oxidation Induction Time (OIT) and Oxidation Onset Temperature (IOT) measurements." "Oxidation Induction Time" refers to the time when heat generation due to oxidation reactions begins, while "Oxidation Onset Temperature" refers to the temperature at which heat generation due to oxidation reactions starts. Using a Differential Scanning Calorimeter (DSC), it is possible to evaluate the susceptibility of plastics and rubber to oxidative degradation with a small amount of sample. 【Measurement Method】 ■ Oxidation Induction Time - After heating in a nitrogen atmosphere, switch to an oxygen atmosphere upon reaching the specified temperature, and measure the time variation of heat at a constant temperature. ■ Oxidation Onset Temperature - Measure the change in heat while heating in an oxygen atmosphere. *For more details, please refer to the related links or feel free to contact us.

Our company conducts "Differential Scanning Calorimetry (DSC)" to evaluate the thermal properties of resin materials, such as melting point (Tm) and glass transition temperature (Tg). The measurement conditions are as follows: temperature range from -100°C to 400°C, measurement atmosphere is Air or N2, and the sample amount is 5mg. Additionally, when performing material qualification of polyethylene (PE), the melting point is measured using DSC, allowing us to determine whether the sample is LDPE (Low-Density Polyethylene) or HDPE (High-Density Polyethylene) based on the differences in melting points. 【Measurement Conditions】 ■ Temperature Range: -100°C to 400°C ■ Measurement Atmosphere: Air, N2 ■ Sample Amount: 5mg ■ Applicable Standards - JIS K7121 Transition Temperature (Melting, Crystallization, Glass Transition) - JIS K7122 Transition Heat *For more details, please refer to the related links or feel free to contact us.

In "Thermomechanical Analysis (TMA)," which is one type of thermal analysis, the dimensional changes such as expansion, compression, and tension of a sample are measured when the temperature changes, allowing for the evaluation of thermal properties such as linear expansion coefficient, glass transition temperature, and softening point. Differences in the flow direction of the resin during molding of resin-molded products (same material) can be confirmed by the different expansion rates and their differences. Physical changes in the sample, such as expansion or contraction due to heating, can be observed. 【Measurement Conditions】 ■ Temperature Range: -100 to 300℃ ■ Measurement Atmosphere: Air, N2 ■ Measurement Mode: Compression, Expansion, Tension, Penetration ■ Applicable Standards: JIS K7196 Penetration Mode JIS K7197, ISO 11359-2 Linear Expansion Coefficient Measurement *For more details, please refer to the related links or feel free to contact us.

In "Thermogravimetric Analysis (TGA)," which is a type of thermal analysis, we measure the weight change of a sample when heated under specific conditions. Simultaneous measurement of Differential Thermal Analysis (DTA) is also possible. This allows us to capture chemical changes accompanied by weight changes such as decomposition, oxidation, and reduction, as well as changes without weight changes such as transitions and crystallization. 【Measurement Conditions】 ■ Temperature Range: Room Temperature to 1300℃ ■ Measurement Atmosphere: Air, N2 ■ Sample Amount: 10mg ■ Corresponding Standards: JIS K7120 (TG/DTA) *For more details, please refer to the related links or feel free to contact us.
