Product specification

Chemical features:

Resistant to weak acids and alkalis, salt solutions, aliphatic hydrocarbons, fats, oils and nonpolar solvents, e.g. gasoline

Material specification:

It is a crystal-clear material with high brilliance, transparency approx. 92 %

High scratch resistance and polishability

Good grinding resistance

Neutral in taste and odour

Physiologically safe

PMMA is printable, paintable and metallizable

High resistance to UV-radiation and weather

Only low formation of smoke when burning

Low toughness, thus impact- and notch-sensitive
