Hydrofluoric Acid
XLW
Hydrofluoric Acid (HF)
Hydrofluoric acid is a transparent, odoriferous, and corrosive liquid that is derived from hydrogen fluoride gas dissolved in water. It is known for its strong corrosive properties and can cause severe burns when it comes into contact with the skin or is inhaled as steam. This hazardous acid has the ability to corrode metals, glass, and materials containing silicon. In laboratory settings, it is commonly produced by combining fluorite, primarily composed of calcium fluoride, with concentrated sulfuric acid. To ensure safety, hydrofluoric acid is typically stored in plastic bottles that are securely sealed and kept in cool storage areas.
Shijiazhuang Xinlongwei Chemical specializes in the production of industrial-grade/food-grade/reagent-grade hydrofluoric acid (HF), CAS 7664-39-3, with a concentration of 55%-70%, meeting international standards. The product is widely used in semiconductor manufacturing, glass etching, petroleum refining, and other fields, and is available in various packaging options including IBC drums, 30kg, and 220kg, with stock available for immediate delivery.

It is crucial to ensure that hydrochloric acid does not exceed a temperature of 100°F (37.8°C) during both storage and delivery. Under no circumstances should the acid be exposed to temperatures above this limit. To prevent excessive heat, it is advisable to keep storage tanks away from direct sunlight.
Elevated temperatures can lead to the degradation of hydrochloric acid and accelerate chemical reactions with the tank materials. This can result in increased off-gassing and the generation of additional odors. In some cases, storing hydrochloric acid may require the use of a Sodium hydroxide (NaOH) scrubber tank to effectively remove and minimize any excess odors.
