Introduction
Polygal Plastics Industries Ltd. offers advanced polycarbonate structured sheets with special selective coatings designed to control light and heat transmission. These coatings are integrated into the sheets through coextrusion, ensuring durability and consistent performance.

Product Specifications

• Primalite: Reflects infrared solar energy while allowing visible light, reducing room heat and air-conditioning costs. Thickness ranges from 8 mm to 32 mm.
• Silhouette: Features a mother-of-pearl lustre with selective warming control. Available in various colors and thicknesses from 8 mm to 40 mm.
• Polycoolite (Primavert): Transmits beneficial solar radiation for plants, reflecting UV and infrared radiation. Ideal for greenhouses, with thicknesses from 10 mm to 32 mm.
• PolyShade: Provides metallic shading, reflecting solar radiation to prevent overheating. Available in silver, metallic blue, and green, with thicknesses from 8 mm to 16 mm.

Technical Considerations
Polycarbonate is a combustible thermoplastic that meets various international standards. It should not be exposed to excessive heat or aromatic solvents. Standard fire precautions are recommended.
