Paraformaldehyde

Paraformaldehyde is available on indent orders in 91 - 97% Prills or powder form. Orders can be placed for 25kg or larger bags and are priced on a per order basis.

Paraformaldehyde is a white crystalline solid, formed by polymerization of methanal gas (formaldehyde, HCHO) by heating.

Essentially it is a solid form of formaldehyde and therefore has the same uses as formaldehyde.

Lower molecule paraformaldehyde is soluble alkali but insoluble in alcohol, ether, and water.

Paraformaldehyde reacts with phenol, urea, melamine or resorcinol to produce resins which are used as binders in plywood and particleboard.

The various resins produced with paraformaldehyde are melamine resin; phenol resin; vinylon; polyacetal resin; terephthalic acid; diphenyl methane diisocyanate, acrylic acid esters,

Use of paraformaldehyde in resin production offers two major advantages as compared with aqueous formaldehyde:

1. more production from existing equipment; and
2. less water (typically twenty fold less) to be removed from the reactor product

Commercially acetal copolymers are also widely used for industrial and automotive applications with excellent balance of properties and processing characteristics.

Paraformaldehyde is also used as fumigant, disinfectant, and fungicide.
