Polycarbonate (PC) Film / Sheet – Optical, Printable & Flame-Retardant PC Films and Sheets
CaiLong Polycarbonate Film / Sheet is produced by precision melt-extrusion / cast processes to deliver the classic PC performance package: high transparency / light transmission, excellent impact resistance, good heat and weather endurance, and reliable dimensional stability.
This category aggregates our PC rolls (thin-gauge films/rolls for converting) and PC sheets (thicker flat sheets for machining, thermoforming and shielding) so buyers can quickly compare grades by function rather than guessing from a single SKU list.
Main grade groups we ship under this family:
-
Optical / Clear PC Film & Sheet: very high light transmission with low haze, used where see-through clarity matters — display windows, lenses/visors, instrument covers, light-diffusing components and protective sight shields.
-
Printing / Textured PC Film (Printable Grade): surface systems tuned for screen/UV/offset print adhesion, die-cutting and folding; common for appliance fascias, control panels, nameplates/legend plates, membrane-switch overlays and sign/display inserts.
-
Flame-Retardant PC Film & Sheet (UL94 V-0 / VTM-0 type grades available): developed for electrical/electronic insulation and enclosure/equipment panels where flammability compliance is mandatory (check exact thickness/cert per grade).
-
Colored / Matte / Frosted PC Film & Sheet (Black, Smoke, Custom Colors): light-block or light-diffuse options for privacy, branding, backlighting or anti-glare, while keeping the toughness PC is known for.
Key characteristics (selection-focused, not lab-report style)
-
High impact strength: significantly tougher than acrylic and far more durable than glass in handling and field use.
-
Thermally capable: commonly rated service range around −40 to +120 °C (some grades/structures higher; verify by specification).
-
Electrically insulating with stable surface/volume resistivity, suitable for spacers, slot liners, barrier insulators and cover plates in low-voltage systems.
-
Convertible: supports slitting, punching, CNC/routing, bending/thermoforming and laminating, depending on gauge and grade.
Typical applications (the searches that land here)
-
Electrical & electronics: insulating washers/spacers, transformer/coil accessories, PCB cover/insulation, power-supply and TV/appliance internal shields.
-
Appliances & equipment fronts: control panels, membrane-switch overlays, nameplates, fascia trims and warning plates.
-
Safety & glazing alternatives: machine-guarding windows, protective visors/goggles, transparent dust/ splash shields (design to relevant safety standards first).
-
Signage & architecture interiors: illuminated signs, lightbox inserts, decorative partitions and display fixtures.
-
Transport interiors: instrument-panel windows, trim covers and utility shrouds where impact and heat matter more than structural load.
Notes & customization
We supply PC film in rolls and PC sheet in plates/cut sizes, with options on thickness, width/length, surface texture (gloss/matte/haircell), and color/transparency.
For projects needing compliance paperwork (UL/ROHS/REACH pathways, food-contact vs industrial-use, etc.), tell us your end-use, thickness range and any certification target — we’ll match grade + issue docs per batch/order.
