Among the most interesting applications of Perclax® methacrylate blocks are AQuariA® Aquarium windows, high technologies pure cast acrylic blocks, specifically produced, certified (PVHO-1) and guaranteed, for underwater use. Over the past several years, this innovative material has been used for the new, large private and public aquarium generation. In addition, AQuariA® acrylic can be bent by thermoforming process in order to obtain large cylinders and tunnels keeping the same unchanged and excellent optical, physical and transparency properties. Hold up the pressure of tons of water. The production of thick pure cast acrylic blocks of high molecular weight, specifically produced, certified and guaranteed for underwater use, is a prerogative of Clax Italia AQuarium Division, and are identified and marked with the AQuariA® brand, which is guarantee of:
- Calibrated and calculated thicknesses, by Clax Italia engineering dept. in accordance with international building codes;
- Physical/chemical properties which consider a constant and static thrust due to water loading on one of the two surfaces;
- High technologies pure cast polymethylmethacrylate (PMMA) blocks, subjected to annealing process;
- Complete polymerization that guarantee less internal material tensions;
- 30 years guarantee against yellowing;
- Surfaces with a minimum of total transmitted light equal or higher than 92%;
BONDING and INSTALLATIONS techniques and technologies for large PMMA components are another important element through which Clax Italia AQuarium Division team can use its know-how. Especially for blocks of big thickness, bonding and installation technologies should be performed without compromising purity and transparency, keeping high mechanical properties. Based on rigorous and meticulous researches, Clax Italia has developed his own chemical adhesives (acrylic resins generally known as “glues”) produced “ad hoc” for this specific field, and not available, as a separate product, on the market.

Technical Details & Test Data
- Technical Details
The production of high thickness cast acrylic blocks with high molecular weight for under water use, is a Clax Italia AQuarium Division’s ® prerogative and it is identified under the trademark AQuariA ®, that also grants:
- Calculated and calibrated thicknesses, chemical and physical properties, according to the static and steady lift due to the water weight upon one of the two surfaces.
- Pure cast polymethilmethacrylate (PMMA) blocks subjected to a normalizing process in order to grant the total polymerisation and the reduction of the material's inside tensions.
- Clear surfaces with a minimum light transmission of ≥ 92%.
- Observance, and certified of the ASME PVHO -1, Safety standards for Pressure Vessels for Human Occupancy .
