Makrolon® WG window grade polycarbonate engineering plate is an optically clear, low stress polycarbonate plate ideally suited for heavily fabricated, tight tolerance parts. It features extremely high impact strength, high modulus of elasticity, outstanding dimensional stability, and good electrical properties. MAKROLON® WG window grade engineering plate has a heat deflection temperature 270°F (132°C) at 264 psi, and demonstrates low levels of black specks and other impurities. Applications include sight windows, viewport windows, and medical parts.
