If only glass reinforcement and organic resin were present, the ignition loss can be considered resin content.

These procedures do not include fluorinated polymers and polymers containing halogenated components. Become a member Sign in Get started.
If organic resin reinforcement is only glass fabric or filament that is entirely decomposed d258 volatile materials under the test conditions and the small amount of volatiles water, residual solvent are ignored, the resin content of the sample is considered as the ignition loss. There are two procedures to determine the organic residue in plastic.

Ignition Loss of Cured Reinforced Resins
The ASTM test method is recommended for evaluating the inorganic residues from plastics ash, which is important to study for the manufacturing process. The ASTM D standard test method is recommended for the unidentified samples, aztm well as for samples where the fusion of the inorganic portions is an issue.
The procedure determines the residual solids in the polymer, however it cannot be used to locate the individual chemical components of ash.
