polyurethane

[brian saban]

Was looking to engrave and cut imitation leather made out of a high end polyurethane and was wondering if it was safe to use.

Yep.........

Stinky stuff - you need good ventilation.

Some nasty byproducts are released when heated, so do be careful.

Note that the byproducts are probably not much worse than from lasering wood, so don't let this put you off.

Health Effects

A range of airborne thermal degradation chemicals may be emitted during combustion of polyurethane products.
These chemicals may include carbon dioxide, carbon monoxide, nitrogen oxides, hydrogen cyanide, isocyanates and amines.
The composition of these chemicals, when emitted in the form of smoke or vapors, may vary.
Exposure to such chemicals may cause irritation of the eyes and respiratory tract with symptoms of running nose, watering eyes, coughing, headaches, dizziness, nausea and breathlessness.
Isocyanates and amines can also cause allergic reactions (sensitization) of the skin and lungs.
Workers exposed to thermal degradation of polyurethanes may experience effects as the exposure occurs or days after exposure has occurred.
Medical attention should be obtained if any symptoms occur.
