Ash

Ash refers to the inorganic residue left after a sample is completely burned at high temperatures, with its content calculated by weighing. It is used to evaluate the proportion of inorganic impurities or fillers in materials, helping to control product quality and raw material purity in industries such as coatings and plastics.
Selection
The selection of an ash content method should take into account the sample properties, temperature requirements, and precision. Match standard testing conditions according to the material type, ensure the equipment can stably reach the set temperature, and calibrate the balance to guarantee accurate weighing.
