FAQ 1: What is Paraformaldehyde used for?
Paraformaldehyde is a polymerized form of formaldehyde widely used in the chemical, pharmaceutical, agrochemical, resin, rubber, textile, and foundry industries. It serves as an important raw material for the production of resins, pesticides, disinfectants, coatings, adhesives, and specialty chemicals.
FAQ 2: What is the difference between Paraformaldehyde and Formaldehyde Solution?
Paraformaldehyde is a solid polymer of formaldehyde, while formaldehyde solution is a liquid containing dissolved formaldehyde. Paraformaldehyde offers higher formaldehyde content, easier storage and transportation, longer shelf life, and controlled formaldehyde release, making it a preferred choice for many industrial applications.
FAQ 3: How should Paraformaldehyde be stored?
Paraformaldehyde should be stored in a cool, dry, and well-ventilated area, away from heat sources, open flames, and strong oxidizing agents. The packaging should remain tightly sealed to prevent moisture absorption and maintain product stability during storage and transportation.
