Poly(Oxymethylene)
Solids containing varying amounts of formaldehyde, probably as paraformaldehyde (polymers of formula HO(CH2O)xH where x averages about 30). A hazard to the environment. Immediate steps should be taken to limit spread to the environment.;Formaldehyde, solution, flammable appears as a colorless aqueous solution of formaldehyde, which is a gas at ordinary conditions. Has a pungent irritating odor. Flash point varies from 122 to 141°F. Denser than water. The vapors are heavier than air and are highly irritating to the nose. Toxic if swallowed. Contact can cause severe injury to the skin accompanied by drying, cracking, and scaling. Used to make plastics, other chemicals, and fertilizers. Used as a preservative and a corrosion inhibitor. Rate of onset: Immediate Persistence: Hours Odor threshold: 1 ppm Source/use/other hazard: Disinfection/germicide; fungicide; textile; health care (tissue fixing).;Formaldehyde, solutions (formalin) (corrosive) appears as a colorless liquid with a pungent irritating odor. Contains 37-50% formaldehyde by mass and varying amounts of methanol, added to prevent precipitation of formaldehyde polymers (formaldehyde exists in solution as CH2(OH)2 and its polymers HO(CH2O)xH where x averages about three). Formalin free of methanol is also shipped but must be kept warm (about 30°C (86°F)) to prevent polymerization. Pure formaldehyde, a gas, is not handled commercially because it tends to polymerize
