The Specific Testing Scope For Polymer Materials.
Dec 11, 2025
The testing of polymer materials covers a wide range of indicators, which can be broadly categorized into the following: mechanical properties testing (such as tensile strength, flexural strength, impact strength, hardness, and compression properties); thermal properties testing (such as heat distortion temperature, Vicat softening point, melt flow index, glass transition temperature, and thermogravimetric analysis); electrical properties testing (such as volume resistivity, surface resistivity, dielectric constant, and dielectric loss); aging and durability testing (such as UV aging, xenon lamp aging, thermal aging, salt spray testing, and humid heat testing); combustion performance testing (such as vertical and horizontal burning tests, oxygen index, and smoke density); and composition and structure analysis (such as Fourier transform infrared spectroscopy, gel permeation chromatography, and differential scanning calorimetry).
The testing scope covers the entire lifecycle from raw materials (resins, masterbatches, additives) and semi-finished products to final products. Specialized evaluations can also be conducted to simulate extreme environmental conditions such as high and low temperatures, acid and alkali corrosion, and fatigue loading, depending on the specific application scenario.
