Class H / 260°C
Engineered for high-dielectric breakdown strength, exceptional thermal stability up to 260°C, and seamless compatibility with Automated Tape Placement (ATP) equipment.
A strategic overview of industrial modernization under France 2030, gigafactory cluster developments in Hauts-de-France, and demanding electro-technical requirements.
Northern France is rapidly consolidating as Europe’s prime electric mobility hub. With major gigafactories (ACC Billy-Berclau, Envision AESC Douai, Verkor Dunkirk, ProLogium), the need for electrolyte-resistant cell termination tapes, dielectric PET barriers, and thermal run-away insulation tapes that exceed UL 94 V-0 flame-retardant thresholds has escalated exponentially.
Anchored by aerospace engineering corridors around Toulouse and Nouvelle-Aquitaine, French avionics demand extreme lightweighting, moisture resistance, and continuous Class H (180°C) to Class 260°C thermal endurance. Polyimide film tapes coated with high-crosslinked polysiloxane adhesives guarantee no outgassing or volatile redeposition in sensitive avionics compartments.
With EDF's EPR2 nuclear construction program and SNCF’s TGV M high-speed rail modernization, electrical insulation criteria demand zero halogen emissions, intense resistance to ionizing radiation, and high mechanical shear strength. Huayuan’s woven glass cloth tapes provide puncture resistance and mechanical anchors for heavy magnet coils and traction motors.
Bridging Chinese manufacturing excellence in Zhuhai and Zhongshan with direct tier-1 and tier-2 French industrial distribution channels.
Unlike simple converters, Huayuan synthesizes specialty acrylics, formulates platinum-cured silicones, and operates high-precision multi-zone coating lines within cleanroom workshops. This vertical integration buffers French Tier-1 clients from raw material fluctuations and guarantees roll-to-roll dielectric uniformity.
Equipped with optical CCD-guided rotary die-cutters and automated slitting machines, we handle log rolls, pancake coils, and complex kiss-cut geometric parts on custom release liners. Tolerance bands are held within ±0.05 mm, ideal for automated pick-and-place lines used by European electronics assemblers.
Consolidated shipments route seamlessly from our Zhuhai and Zhongshan plants through Shenzhen and Hong Kong container hubs to French ports (Le Havre, Fos-sur-Mer) in 28-32 days, or via air freight (CDG Paris) within 5 days for time-sensitive prototype trials and pilot line validation runs.
Ensuring complete peace of mind for European procurement departments through zero-compromise environmental and dielectric validation.
All tapes supplied to European enterprises are rigorously tested by SGS and certified free of Substance of Very High Concern (SVHC) chemicals under EU Regulation (EC) No 1907/2006. Flame retardants avoid decaBDE and comply strictly with halogen-free standards (IEC 61249-2-21).
Our insulating tapes conform to standard electrical classifications under NF EN 60454 (Pressure-sensitive adhesive tapes for electrical purposes). Selected formulations hold recognized UL 510 flame retardancy component certifications, assuring compliance in end-products exported across global jurisdictions.
Responding to France’s circular economy policies (Loi AGEC), Huayuan’s R&D department is pioneering thermally reversible double-sided tapes and clean-stripping adhesive tapes that enable straightforward battery pack disassembly, cell second-life repurposing, and high-purity recycling.

In-depth responses covering adhesive chemistry, dielectric testing, logistics timelines, and European standards compliance.
Every raw material batch (polyimide, PET film, copper foil, acrylics, and silicones) is verified via independent third-party SGS/TÜV testing before enters the coating line. We guarantee complete absence of decabromodiphenyl ether (DecaBDE), perfluorooctane sulfonate (PFOS), and short-chain chlorinated paraffins (SCCP). Standard declarations of conformity (DoC), full chemical disclosures, and REACH SVHC declarations are supplied alongside each commercial invoice and bill of lading.
Huayuan standard 0.05 mm polyimide (Kapton equivalent) tapes deliver a dielectric breakdown strength exceeding 6,500 volts (ASTM D149 test standard), while our specialized battery-grade PET films achieve between 5,000V and 8,000V depending on film thickness and crosslink density. Test coupons from every master roll are sampled and subjected to high-potential (Hi-Pot) verification within our in-house ISO 9001 quality lab.
Yes. Huayuan provides precise functional drop-in equivalents for widely specified industrial grades such as 3M 5413 (Polyimide), 3M 69 (Glass Cloth Tape), 3M 1350F (PET Mylar), and Tesa 51408. We provide cross-reference matrix documentation, dual-branded comparative TDS, and pre-cut sample rolls allowing French quality engineers to validate thermal, tensile, and peel adhesive performance on their own machinery prior to PO placement.
Standard production lead times range between 7 to 12 business days for slit rolls and custom die-cuts. We support FOB Shenzhen/Hong Kong, CIF Le Havre/Fos-sur-Mer, and DDP terms directly to your warehouse across mainland France. Fast sampling and urgent pilot runs are dispatched by DHL/FedEx Express directly to your testing facilities within 3 to 5 business days.
Our lithium-ion battery cell termination tapes utilize ultra-pure, special-cured acrylic adhesive formulations specifically engineered to resist solvent dissolution and swelling when immersed in LiPF6 electrolyte solvents (including EC, DEC, DMC, and EMC) at temperatures up to 85°C. The tapes retain peel adhesion without leaching ionic impurities that could degrade cyclic battery life or cause micro-shorts.
