Versatile Compact Polycarbonate for Heavy-Duty Applications

"Our factory in Mexico uses policarbonato compacto from Sinhai for machine guards. The 10mm solid sheets are impact-resistant and easy to clean, meeting OSHA standards. The clear finish allows for visual monitoring, while the chemical-resistant surface withstands industrial solvents. Reliable and compliant with safety regulations."

"A school in Japan installed policarbonato compacto for corridor glazing. The impact-resistant sheets meet earthquake safety standards, and the frosted finish provides privacy while allowing light. The easy-to-install panels reduced construction time, and the fire-resistant properties gave us peace of mind. Practical and secure."
