Physiological and toxicological evaluation

Closed-cell ROHACELL® foam is

  • water–insoluble
  • largely physiologically inert
  • not absorbed through the skin, respiratory tract, or gastrointestinal tract due to its high molecular weight.
  • No systemic toxicity is expected from single or even multiple exposure.

As in the case of other inert dusts, exposure to ROHACELL® dusts could possibly result in mechanical irritation in the upper respiratory passages and the mucous membranes of the eye. Product dust can remove natural moisture from the skin, and the resulting drying of the skin could cause irritation in some cases. Sensitization is not expected.

To the best of our present knowledge, ROHACELL® has no adverse effects on man, animals, plants, or microorganisms at ambient conditions.

Environmental compatibility and safety

ROHACELL® foam is non-hazardous, not governed by any particular safety regulations, and non-water-polluting. It can be disposed of in accordance with local ordinances.


ROHACELL® cannot be materially recycled. If possible, incinerate in a common combustion plant instead of landfilling as a disposal method.

Fire Behavior

Flammable gases generated by degradation may be released at temperatures above 350°C. Since the spectrum of crack and combustion products depends heavily on the combustion conditions, it is not possible to make any general statements in this regard.

Ventilation and Exhaust during Processing

No dangerous byproducts are formed if ROHACELL® is correctly processed.
Processing ROHACELL® with heating wire may generate gases harmful to health. If, against our recommendation, ROHACELL® is processed in this way, care must be taken to safeguard employees from exposure, for example, by a suitable ventilation system.
