Polyamide, GF-reinforced
Polyamide is resistant to almost all organic solvents (concentrated sulphuric acid, 90%
Formic acid, m-cresol, phenol) fuels, greases and mineral oils, diluted inorganic acids
and alkalis up to 20% NaOH and KOH solutions, liquid ammonia and sulphur dioxide.

Remarks

(1) Containers made of copper and copper-rich alloys must not be used, as explosive copper acetylides can form.
(2) Apparatus and installations which come into contact with food and beverages should be coated in tin so that no impairment of the colour or taste of foods can occur through the absorption of copper ions.
(3) In the case of oxygenated copper grades, the influence of hydrogen at high temperatures leads to embrittlement (hydrogen sickness).
