Material
No ozone depleting substances in the products.
All front parts are made of polycarbonate
Material Characteristics
PC Polycarbonate High impact strength, good outdoor resis-
tance.
Chemical resistance - See table below
PSU Polysulphone Can withstand high temperatures, acids,
basic solutions, alkaline compounds,
oils, alcohols.
PA Polyamide Can withstand high temperatures, ali-
phatic, aromatic and chlorinated hydro -
carbons, esters, ketone-aldehydes,
alcohols and basic solutions.
PBT Can withstand high temperature, aliphatic
and aromatic hydrocarbons, acids, basic
solutions, alcohols, grease and oils
Zinc Good corrosion resistance in inland-,
sea and industrial atmosphere.
Light-alloy Good corrosion resistance in inland-,
sea and industrial atmosphere.
Chemical resistance for polycarbonate
Chemical class Effects
Acids No signicant effect under most typical
conditions of concentration and temper-
ture
Alcohols & Alkalis Generally compatible at low concentra-
tion and room temperature. Higher
concentrations and elevated tempera-
tures can result in etching and attack
evidenced by decomposition.
Aliphatic Hydrocarbons Generally compatible
Amines Surface crystallization and chemical at-
tack. Avoid.
Aromatic Hydrocarbons Partial solvents and severe stress crack-
ing agents (i.e., xylene, toulene). Avoid.
Detergents and Cleaners Mild soap solutions are generally compa-
tible. Strong alkaline materials should be
avoided.
Esters Cause severe crystallization. Partial sol-
vents. Avoid.
Greases and Oils Pure petroleum types generally compa-
tible. Many additives used with them are
not.
Halogenerated Hydrocar-
bons Solvents. Aoid.
Ketones Cause severe crystallization and stress
cracking. Partial solvents. Avoid.
Silicone Oil and Greases Generally compatible up to 85 oC.
