PC — Lexan / Makrolon

Polycarbonate

Polycarbonate is an exceptionally tough, transparent thermoplastic with impact resistance approximately 250 times greater than glass. We stock polycarbonate sheet in clear, matt, velvet, white sand, and UVX-stabilised finishes, making it our top recommendation for machine guards, safety glazing, and electrical housings.

Available Grades

Brands we stock: Lexan, Makrolon

PC Clear

Optically clear polycarbonate sheet with outstanding impact resistance and good light transmission. Our standard grade for machine guards, safety glazing, and transparent enclosures.

PC Matt / Velvet Finish

Polycarbonate sheet with a matt or velvet-textured surface to reduce glare and fingerprint visibility. Ideal for display housings, control panels, and consumer-facing equipment.

PC White Sand

White sand-textured polycarbonate offering excellent light diffusion. Used for luminaire covers, LED diffusers, and decorative architectural panels.

PC UVX-Stabilised

UV-stabilised polycarbonate with enhanced resistance to yellowing and degradation from prolonged sun exposure. Our recommended grade for outdoor glazing, skylights, and any exterior application.

PC Thin Film (0.127–0.5 mm)

Thin-gauge polycarbonate film for electrical insulation, membrane overlays, and flexible display windows. Offers the same toughness as thicker sheet in a conformable format.
