Product Introduction
Paraformaldehyde is the polymerized, solid form of formaldehyde. It appears as white, free-flowing granules or powder and is commonly available in 91% and 96% purity grades. Upon depolymerization—often via heat—it releases formaldehyde gas. Widely used in resin synthesis, disinfectants, and histology reagents.
