Combustion performance is evaluated using the oxygen index method or the cone calorimeter method, utilizing instruments such as oxygen index testers and smoke density testers. Thermal conductivity is determined via the steady-state hot plate method or the laser flash method, using a thermal conductivity tester. For mechanical property testing, compressive strength is measured using a universal testing machine, while peel strength is assessed using a peel tester via the 180° peel test method.
Environmental performance analysis involves the use of gas chromatography-mass spectrometry (GC-MS) to detect volatile organic compounds (VOCs), and atomic absorption spectroscopy to determine heavy metal content. Water absorption is tested by the immersion-weighing method, employing a constant-temperature water bath and a precision balance.
