We will evaluate the degree of degradation of polymer materials using FT-IR.
Unlike metal materials, polymer materials such as plastics are less prone to corrosion like rust; however, they can deteriorate due to heat and ultraviolet light. Yellowing, commonly seen in plastics, is one such example. In degradation analysis services, FT-IR is used to evaluate the degree of deterioration in such samples. The results can be utilized as a material for identifying the cause of defects in products that show signs of damage.

basic information
**Features** ● Estimation of structural changes from bonding FT-IR allows for the inference of what types of bonds and structures the measured sample possesses, as the absorption due to molecular vibrations appears in the spectrum. ● Mapping measurements using microscopic FT-IR Surface mapping analysis can be performed using microscopic reflection or microscopic ATR methods. This enables a visual assessment of the differences in the degree of degradation on the sample surface. ● Evaluation of samples including tests such as thermal treatment and chemical immersion We conduct evaluations, including tests, on products that have been subjected to deteriorating environments or tested under specific conditions.

Applications/Examples of results
●Analysis of Resin Degradation Resins undergo structural changes due to heating and repeated heating and cooling. The most commonly observed structural change is oxidation, which occurs due to factors such as heat and ultraviolet light. ●Analysis of Defective Products Degradation ●Analysis to Confirm Structural Changes in Resin Due to Heat Treatment Heated polyethylene exhibits absorption due to oxidation, such as C=O and C-O, and these absorptions increase as the temperature rises.
Company information
Our main business is providing technical services to evaluate the reliability of developed products. We not only provide evaluation data in accordance with standards and regulations, but also propose optimal methods, conditions, and equipment for evaluation purposes, as well as design and manufacture original equipment and jigs for non-standard evaluations. Additionally, we handle three evaluation techniques—measurement, testing, and analysis—comprehensively, allowing us to offer complex services that span diverse equipment and suggest more multifaceted evaluation methods.
