PHOSPHORIC ACID CONCENTRATED TO 158°F Chemical compatibility with O-rings, rubbers, & plastics

Concentrated phosphoric acid heated to 158°F is used in various industrial processes that require higher reactivity. This condition enhances its effectiveness in applications such as metal cleaning, etching, and chemical synthesis. The elevated temperature increases the risk of burns and respiratory irritation, necessitating strict safety measures. Handling should involve protective equipment, including heat-resistant gloves, goggles, and face shields. Proper ventilation is critical to avoid inhalation of fumes. Storage should be in heat-resistant, corrosion-resistant containers, away from incompatible materials like strong bases and reactive metals. In the event of spills, immediate neutralization and cleanup are required to prevent hazards. This form of phosphoric acid is particularly potent, making it effective for demanding industrial applications where controlled high-temperature acidic conditions are essential.
