Dafu

Founded in 2009 and based in Foshan, Guangdong, Dafu is a national "Little Giant" high-tech enterprise focused on advanced polymer films. While we're known globally for 5G-grade LCP/PEEK films (in Huawei / vivo / OPPO / Samsung supply chains), our fast-growing BOPP dielectric film line is what Indian capacitor makers are asking about.

Production at a glance

• German Bruckner simultaneous-stretch line + synchronized line, mother roll width up to 6,400 mm

• Annual BOPP capacitor film capacity: 5,600+ tonnes

• Thickness range: 2 / 2.8 / 3 / 4 / 5 / 6 / 8 μm — 2μm in mass production

• Rated temperature: 105°C std / 125°C high-temp grade (Borealis / Hanwha high-isotacticity PP base)

• Dielectric strength ≥ 520 V/μm, low defect density, CV ≤ 2% (cross-direction)

Serving Indian market

Indian EV two-wheeler / four-wheeler inverters, solar PV inverters, and smart-meter capacitors are scaling fast — but ultra-thin supply is still concentrated in Xpro (domestic) and Toray (import). Dafu offers a stable China alternative:

✓ Shorter lead time vs. import Europe/Japan

✓ MOQ flexible for trial rolls

✓ A4 samples & 100 m pilot rolls available ex-stock

✓ Mumbai / Chennai port delivery 15–20 days

Compliance & testing

• IEC 60384-1 / IEC 60664 reference test reports available

• In-house lab: breakdown voltage, self-healing, high-temp aging, TD/MD shrinkage

• IS 17067 alignment on request

Whether you're a capacitor OEM looking to dual-source beyond Xpro, or an EV inverter maker pushing from 4μm → 2.8μm → 2μm — we're ready to ship samples.
