The analysis device also supports the analysis and evaluation of polymers! Information on the configuration and principles of high-temperature SEC equipment is provided!

The molecular weight of resins such as plastics is not a single value but is composed of multiple molecular weights. By understanding this molecular weight and its distribution, it leads to a better understanding of the characteristics and degradation mechanisms of the resin. In this document, we will introduce a case study where we measured polypropylene resin (PP) samples with and without ultraviolet (UV) irradiation using a high-temperature GPC device suitable for measuring polyolefin-based materials that are difficult to dissolve in solvents at room temperature, and conducted data analysis. We encourage you to read it. [Contents] ■ Configuration and principles of high-temperature SEC ■ Analysis case: Molecular weight measurement of PP subjected to UV irradiation ■ Application examples ■ Specifications and considerations for high-temperature SEC *For more details, please refer to the PDF document or feel free to contact us.

Poisson's ratio measurement

  • Product news

At Aites Co., Ltd., we conduct "Poisson's ratio measurement." Poisson's ratio is the ratio of longitudinal to lateral strain that occurs when a load is applied to an object, and it is necessary for strength calculations of materials. In the downloadable materials, we introduce the results of attaching strain gauges to test specimens, applying tensile loads using a universal testing machine, and examining the longitudinal and lateral strains obtained from the strain gauges. Please feel free to download and take a look.

Chemical Analysis Concierge Service

  • Product news

We would like to introduce our "Chemical Analysis - Trust Us Service." When conducting component analysis of foreign substances or stains on products, it can be challenging to determine whether organic analysis or inorganic analysis is more suitable, and which specific analysis within organic or inorganic is the most appropriate. We provide a comprehensive service for customers who are struggling with the selection of analysis methods. Since each analysis device can measure different targets, it is necessary to choose a method that fits the purpose based on the information available.

Tensile test

  • Product news

The "tensile test" is a test that measures the load and displacement (elongation) when a material is pulled at a constant speed, in order to determine the physical and mechanical properties of the material. By pulling the test specimen in a temperature-controlled chamber, it is possible to determine and understand the temperature dependence of these properties. Our company is capable of conducting material property tests under temperature-controlled conditions. We can also propose conditions tailored to the materials and properties you wish to measure. Please feel free to consult with us.
