General Resistance

Lustrolite is chemically resistant to the following substances:

  • Kerosene
  • Bleach
  • Mineral Spirits
  • 10% Citric Acid
  • Lemon Juice

  • Glass Cleaner

Lustrolite should not be exposed the following substances:

  • Acetone
  • Methylated Spirit
  • Abrasive cleaners
  • Aggressive solvents such as Toluene.
Fire Properties

Most building codes recognize that most thermoplastics do not meet all the ASTM E 84 testing requirements for Interior Finishes as it’s a ceiling based test and therefore unsuitable for thermoplastics that may melt or drip.

An alternative testing criteria has been established in the code for Light Transmitting Plastics. Lustrolite acrylic panels comply with the International Building Code for Light Transmitting Plastics (being ASTM D-2943 and ASTM D-635).

However Lustrolite is a combustible thermoplastic so appropriate fire precautions should always be observed.
