ABS - Acrylonitrile butadiene styrene - amorphous thermoplastic copolymer
Material with good chemical resistance. It is resistant to weak or dilute oxidizing agents, acids and alkalis, but not to their strong concentrates.It is resistant to low and high temperatures.It is insoluble in water. It can be bonded with solvent adhesives based on toluene and methylene chloride as well as polyacralate adhesives.
Cr - Chrome finish
A thin layer of chromium protects the surface of objects from corrosion and increases their hardness. Chromium has very good corrosion and chemical resistance.It is resistant to both acidic and alkaline environments except for hydrochloric acid, in which it dissolves, and chloride salts, which cause pitting corrosion. It is resistant to abrasion.
