Black PC is safe. Gray PC is practical. But when your project calls for warmth, depth, and a high-end furniture-like finish—without sacrificing the impact strength and heat resistance of polycarbonate—Dark Brown Opaque PC Sheet​ is the answer.

Widely specified for power supply insulation, display backing, metallizing bases, and decorative panels, dark brown PC delivers the "invisible workhorse" performance engineers need and the "premium touch" designers want.

Why Dark Brown? (Not Just "Another Color")

Most buyers default to Black​ for opacity and Gray​ for neutrality. Dark brown is the underused middle ground:

• Warmer than black​ – Less "industrial," more "premium consumer." Perfect for audio equipment, smart home panels, and furniture-grade electronics.
• Zero light bleed​ – Opaque formulation blocks 99%+ transmission, making it ideal for light shielding​ behind display bezels.
• Insulation + Shielding​ – Retains PC's dielectric strength, so it doubles as a concealed insulator​ in SMPS, monitors, and office machines.
• Metallizing-ready​ – Dark brown substrate is a preferred base for vacuum metallizing​ (gold/silver/chrome finish topcoat), giving jewelry-box luxury without bare metal cost.
• Fade-resistant pigment​ – UV-stable formulation keeps the brown from turning muddy after prolonged indoor/outdoor exposure.

Product Specifications (Dark Brown Opaque PC)

Based on DAFU's opaque color PC platform:

Performance values below reference the PC resin platform (consistent with DFPC11 clear grade):

Deep brown shares the same flame-retardant PC base as DAFU's clear grades, so you get UL94 V-2 compliance​ even in colored form—critical for power supply and appliance enclosures.

Where Dark Brown Opaque PC Gets Used

From the product page and DAFU's opaque PC application notes, key scenarios include:

1. Power Supply & SMPS Insulation​ – Concealed inner shields in adapters, TV/monitor drivers, office machine backplanes. Opaque = no light leak; PC = dielectric barrier.
2. TV / Monitor Bezels & Backing​ – Dark brown gives a "frameless black-but-richer" look behind screen assemblies.
3. Instrument & Meter Panels​ – Water/electric meter faces, automotive dashboard sub-panels. Printable surface for nameplates.
4. Metallizing Base Substrate​ – Vacuum-metallized decorative parts (logo badges, cosmetic caps). Brown underlayer enriches gold/copper metallics.
5. Sports & Lifestyle​ – Sun hat brims, ski goggle frames, sunglasses decorative inserts (paired with tint/lens laminate).
6. Decorative Signage & Architectural Accents​ – Colored light boxes, outdoor trim, creative packaging where a wood-adjacent tone is preferred over stark black.

Dark Brown vs. Black vs. Gray – Quick Pick

FAQ: Sourcing Dark Brown PC Sheet

Q: Can dark brown PC be silk-screen printed?​

A: Yes. The gloss/gloss surface accepts solvent, UV, and pad-printing inks well. For maximum durability, reverse-side (second-surface) printing is recommended—the opaque brown already blocks backlight, so your print sits protected.

Q: Is this the same as "Bronze Polycarbonate" used in roofing?​

A: No—those are thick (3–10mm) bronze translucentsolid sheets for canopies . DAFU's dark brown PC here is 0.1–3.5mm thin-gauge film/sheet​ for electronics, overlays, and metallizing—completely different application family.

Q: Can I get other browns or custom colors?​

A: Yes. DAFU's opaque color PC platform supports customer-specified colors​ —light tan, coffee, walnut, or matched Pantone. MOQ applies on custom runs.

Q: Does the brown affect flame rating?​

A: The color masterbatch is formulated into the same UL-compliant PC resin, so UL94 V-2 (≥0.25mm) is retained—but always request the specific batch's yellow card if you're submitting for final certification.
