CLAREX Low Moisture Absorption Acrylic (LA1)
Special formulation that absorbs less moisture than standard acrylic.
CLAREX Low Moisture Absorption Acrylic is a great choice for laminating applications since the sheet will have less tendency to cause the laminated stack to bow. It has also been beneficial for printing applications, allowing for higher definition.
Benefits
- Optical Grade Cell-Cast Acrylic
- Minimize warp caused by moisture absorption
- Tighter dimensional tolerances of parts is possible
- Allows higher definition printing
- UV Transmission types are also available
- No retardation / No birefringence
Applications
- Laminations
- Printing
