Cast acrylic sheets are manufactured by pumping MMA (Methyl Methacrylate monomer) liquid into glass molds. These molds are then submergend in warm water and the process of ploymerization takes place. Acrylic sheets, therefore, may vary up to 10% in thickness across the sheet. This is compensated by a wider range of thickness, superior properties regarding surface finish and hardness, greater ease of fabrication and a variety of color and effect options.

PERSPEX Cast acrylic sheets have an outstanding resistance to long-term exposure to sunlight and weathering, UV resistance and a 10 year guarantee. Clear cast acrylic sheets have up to 30 year guarantee.
