Spacer made of PMMA
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
