Description

Paraformaldehyde White Powder Polyoxymethylene 96% CAS 30525-89-4 for Chemicals

Polyethylene (IUPAC names Polyoxymethylene, POM) a polymer of formaldehyde (high molecular weight polyethylene), generally having a structural length of eight to one hundred units. Long chain polyformaldehyde is commonly made in heat-resistant plastics, also known as polyformaldehyde plastics. White flammable crystalline powder with formaldehyde odor. Dissolves slowly in cold water and quickly in hot water. The solubility of water at 20ºC is 0.24g/100cm3H2O.
