| Project Background

The ash content is a key indicator for evaluating the inorganic residues (such as catalyst residues, fillers, and flame retardants) in polymer materials, which directly affects the purity, electrical insulation, and combustion performance of the materials. Accurately determining the ash content is of great significance for controlling the production process (such as the biosafety of medical implant materials), evaluating the addition efficiency of flame retardants (such as the flame-retardant grade of electronic enclosures), and recycling waste (such as predicting the pyrolysis residue rate of plastics).

| Project Overview

This test uses the high-temperature calcination method: accurately weigh the sample in a pre-treated and constant-weight crucible, calcine it at a specific temperature until the organic matter is completely oxidized, weigh the mass of the remaining inorganic matter after cooling, and calculate the ash percentage. This method can simultaneously identify the types of inorganic fillers (such as the thermal decomposition differences between calcium carbonate and talc powder).
