In the competitive landscape of electronics manufacturing, material selection is critical. Engineers require materials that offer high dielectric strength, thermal stability, and regulatory compliance. Traditional insulating materials often face challenges with halogen content or dimensional stability.
Enter DAFPC DFPCR34: a high-performance, black, halogen-free flame-retardant polycarbonate (PC) film. Designed specifically for power supply insulation and display module shielding, this material offers a sustainable alternative without compromising safety.

What is DFPCR34?
DFPCR34 is a specialized black polycarbonate film manufactured by Foshan DAFPC New Material Co., Ltd. It is engineered to provide total opacity for light-blocking applications while meeting stringent environmental standards (RoHS, PFOS/PFOA free).
It serves as an ideal substitute for epoxy boards, pressboard, and metal shields in applications requiring both electrical isolation and structural support.

Performance Data: Why Choose DFPCR34?
Technical buyers need data. Here is how DFPCR34 performs against industry requirements:
1. Electrical Properties (Safety First)
- Dielectric Strength: ≥ 20 KV/mm (@10 mils thickness). This ensures reliable protection against electrical breakdown in high-voltage environments.
- Volume Resistivity: > 1×10¹⁶ Ω·cm. Superior insulation properties prevent current leakage.
- Flame Rating: UL94 V-0 (at thicknesses ≥ 0.5mm). Stops fire propagation immediately.
2. Thermal & Mechanical Stability
- Vicat Softening Point: 135°C. Withstands reflow soldering and high-temperature operating conditions.
- Low Shrinkage: ≤ 1% at 135°C. Maintains precise dimensions after thermal processing—critical for automated assembly.
- Impact Resistance: Inherits PC’s legendary toughness (Tensile Strength ≥ 55 MPa), preventing cracks during handling.
3. Environmental Compliance
DFPCR34 is certified clean. All hazardous substances are Non-Detected (N.D.):
- ✅ RoHS Compliant
- ✅ Halogen Free (Cl, Br < 900ppm)
- ✅ PFOS/PFOA Free
- ✅ Heavy Metals Free (Pb, Cd, Hg, Cr6+)
