PHOSPHORIC ACID, 20% Chemical compatibility with O-rings, rubbers, & plastics

Phosphoric acid at 20% concentration is a less concentrated form used in various applications requiring milder acidity. It is utilized in food processing as a pH adjuster, in fertilizers, and in cleaning products. This concentration reduces the risk of severe burns compared to higher concentrations but still requires careful handling to avoid skin and eye irritation. Protective equipment such as gloves and safety glasses is recommended. Storage should be in corrosion-resistant containers, away from incompatible substances. Proper ventilation is necessary to prevent the buildup of fumes. In case of spills, neutralization and cleanup should be carried out promptly to minimize environmental and health risks. The 20% concentration offers a balance between effectiveness and safety, making it suitable for applications where a moderate acidic strength is required.
