Identification of polymer materials
Introduction
The identification of polymer materials involves qualitative or quantitative analysis and characterization of their composition, structure, and properties. Polymer materials are widely used in plastics, rubber, fibers, coatings, and composite materials, and they encompass a wide variety of types (such as polyethylene, polypropylene, polyamide, and elastomers), often containing copolymers, blends, additives, and fillers. In production, quality control, and failure analysis, it is necessary to determine the material's chemical structure (such as monomer composition, stereoconfiguration, and degree of crosslinking), thermal properties, molecular weight distribution, and impurity content to ensure stable product performance, meet application requirements, and comply with environmental and safety regulations. Therefore, systematic identification using infrared spectroscopy has become an important part of polymer science and engineering.

Solution
Attenuated Total Reflection (ATR) Method
Application: Suitable for infrared spectroscopy testing of tablets, plastic bottles, films, sheets, and rubber samples.
Required Accessory: Single-reflection ATR accessory (standard with zinc selenide crystal; optional diamond or germanium crystals available).
Working Principle: The measurement is based on the principle of total internal reflection.
Procedure
1)Take a properly cleaned and flat sample, and then press it firmly against the ATR crystal (ZnSe, zinc selenide).
2)The infrared spectrum is directly recorded via reflection.
3)The entire process is fast and simple, requiring no sample pretreatment to meet testing requirements.
