Ash Analysis is performed in order to evaluate the weight percent of total fillers in rubber compounds. Fillers are typically non-reinforcing, inorganic additives such as clays, chalk, metal oxides, silicas and silicates added to modify and improve on certain physical or physical-chemical properties such as resistance to abrasion, permeation, swell, tear, or perhaps even modifying product cost without reducing the required performance.
ARDL’s methodologies for Ash Analysis can be found on our Ash Content page.
