Rubber Chemical Accelerator Purity Testing
ASTM D5297 is a testing standard established by the American Society for Testing and Materials that is used to determine the purity of rubber chemical accelerators using High Performance Liquid Chromatography, or HPLC. Rubber accelerators are chemicals used in the vulcanization process to speed up the curing of rubber, and their purity can determine performance and quality in the final rubber products. ATS performs rubber chemical accelerator purity testing to help clients assess the purity of these accelerators, ensuring they meet the necessary specifications for their intended use.
The vulcanization process is a chemical reaction that improves the mechanical properties of rubber, making it stronger, more elastic, and more durable. Impurities in these accelerators can adversely affect the vulcanization process, leading to defective or underperforming rubber products that could ultimately lead to failure. ATS’ ASTM D5297 testing services provide a reliable method to verify that accelerators are free of impurities that could compromise product quality.
Testing Procedure
Rubber accelerators are used to speed up the cross-linking process between sulfur and rubber molecules. Common accelerators include thiurams, dithiocarbamates, and sulfenamides. Each type of rubber accelerator has specific performance characteristics, and its purity affects the rate of vulcanization, as well as the physical properties of the final rubber product. Our highly experienced chemists perform High Performance Liquid Chromatography to separate, identify, and quantify individual components in a mixture. In ASTM D5297, HPLC is used to determine the purity of rubber accelerators by isolating the target chemical from any impurities or related compounds. HPLC is accurate and cost-efficient for quickly analyzing complex mixtures and determining purity. Rubber accelerator purity is expressed as a percentage, comparing the chromatographic peak of the target accelerator to those of any impurities or degradation products present in the sample.
