Polycarbonate (PC) is a high strength material intended for tough environments and engineering applications. It has extremely high heat deflection, and impact resistance. Polycarbonate also has a high glass transition temperature of 150° Celsius. This means it will maintain its structural integrity up to that temperature. It can also be bent without breaking and is often used in applications where some minor flexibility is required.

Polycarbonate is extremely hygroscopic, meaning it will absorb moisture from the air, which will affect its strength.

Double the impact resistance of PETG and almost unbreakable, polycarbonate key strength lies in its durability. With shatter free properties, polycarbonate provides as an ideal substitution to glass. Mirror polycarbonate is often found in hospitals and areas open to the public. Like acrylic, polycarbonate offers crystal clear clarity in its standard finish. Various opaque light transmission grades, are also available across the opal range (from 18% up to 40%). Depending on the thickness of polycarbonate visible light can vary.

Application areas include, signage, machine guard, greenhouse, glazing and skylights.

PROS

  • Impact resistant

  • High heat resistance

  • Naturally transparent

  • Bendable without breaking

  • Half the weight of glass

CONS

  • Prone to warping

  • Absorbs moisture from the air

  • Scratching can occur easier than that of rival substrates like acrylic or PETGB
