Polycarbonate is a strong, clear plastic with excellent rigidity, strength, and impact resistance. Machine guards, signage, architectural glazing, face shields, skylights, and point-of-purchase displays all benefit from polycarbonate’s optical clarity. Polycarbonate is a fantastic material for applications that require both transparency and strong impact resistance. It is frequently used in eyeglasses since it is a lighter alternative to glass and a natural UV filter.
PC is categorised as a “thermoplastic,” which refers to the way the material reacts to heat. The ability of thermoplastics to be heated to their melting point, chilled, and reheated without substantial deterioration is a key feature.
POLYCARBONATE IS WIDELY USED FOR:
- Indoor and outdoor signs
- Architectural glazing—medical facilities, retail and government buildings, and transportation centers at risk from breakage and vandalism
- POP displays and graphic holders
- Face shields
- Machine guards, sight glasses
- Semiconductor machinery components
- Transparent manifolds
- Outstanding toughness
- Good optical clarity
- (non-machine grade or un-filled) Strong and stiff
- Good electrical insulation
- Easy to fabricate, machine, and thermoform
- Easy to bond with solvent cements

Polycarbonate Properties and Material Options
TUFFAK® Polycarbonate– Tough and half the weight of plate glass, allows structural applications to require less support. Polycarbonate sheet thermoforms well, is easy to paint, and bonds well using solvent cements or adhesives. Polycarbonate sheet, rod, and tube are easy to machine and have excellent dimensional stability.
General Purpose Polycarbonate– Unfilled grades of polycarbonate exhibit glass-like transparency and extreme toughness. General purpose polycarbonate sheet has a polished surface, is UV stabilized, and is often used in glazing applications. It features outstanding impact strength and superior dimensional stability. TUFFAK® GP polycarbonate has a 5-year warranty against breakage, making it cost effective for thermoformed parts and fabricated components.
AMGARD™ Polycarbonate for Safety Shields– A transparent polycarbonate sheet formulated with a silver ion antimicrobial agent that protects the sheet surface against the growth of microorganisms such as bacteria, mold and mildew that cause stains and odors. AMGARD™ provides additional surface protection between cleanings and complies with applicable EPA requirements as a Treated Article.
Machine Grade Polycarbonate– This low stress polycarbonate is used in many applications that require heavily fabricated, tight tolerance parts such as electrical insulator components, manifolds, diaphragms, and semiconductor parts. Machine grade polycarbonate has high impact strength, high modulus of elasticity, outstanding dimensional stability, and good electrical properties.
Glass-Filled Polycarbonate– This glass-reinforced polycarbonate is used in many industrial applications where metals are commonly used. The addition of glass fibers provide improved strength and stiffness and lower the thermal expansion. Various amounts of glass fibers may be added from 10% – 40%. While glass-reinforced polycarbonate has less impact strength than standard grades, it is still tougher and more impact resistant than most other plastics and die cast aluminum.
TUFFAK® POLYCARBONATE MATERIALS
TUFFAK® AR Polycarbonate Sheet– Has a transparent hard coat finish, which provides the material with enhanced weatherability, chemical resistance, and abrasion resistance and often used for glazing applications in high traffic areas such as bus shelters.
TUFFAK® AR abrasion resistant polycarbonate sheet offers higher abrasion resistance and surface hardness to polycarbonate’s inherent performance benefits of impact, strength and clarity.
Backed by a limited 7-year warranty against breakage and loss of light transmission, TUFFAK® AR abrasion resistant polycarbonate sheet features a proprietary hard coat technology that offers protection against chemical and UV attack. Over its lifecycle, this results in a significant reduction in maintenance cost and liability risk versus that of other glazing materials.
TUFFAK® Lumen XT Polycarbonate Sheet– A translucent polycarbonate product with a textured surface on one side specifically designed for lighting lenses. It features a unique combination of high light diffusion and high light transmission through a combination of optimized surface texture and advanced diffuser technologies.
When compared to other light diffusing products such as glass and acrylic, TUFFAK® Lumen XT sheet has superior impact strength and toughness. Its higher flammability resistance and wider service temperature range provide an additional performance advantage over acrylic diffusers.
The wide range of standard diffusion levels as well as both a warm (LW) or a cool (LC) hue offers designers the flexibility to maximize light fixtures’ aesthetics and performance.
TUFFAK® SL Polycarbonate Sheet (Sign Grade)– A polycarbonate product with enhanced UV resistance, exceptional weatherability, and superior impact strength designed for signage. TUFFAK® SL Sign Grade polycarbonate sheet, available in sheet and reel, meets UL 879 for electrical signage, and can be easily fabricated, thermoformed, and decorated. Available in clear or colors.
