View Product Specs
Verified laboratory-grade pressure-sensitive tapes produced under cleanroom precision slitting standards for aerospace, electronics, and automotive OEMs.
Deep technical insights into poly(4,4'-oxydiphenylene-pyromellitimide) backings, cross-linked polydimethylsiloxane adhesion, and critical high-temperature limits.
In high-reliability industrial production, standard insulating carriers such as PVC, polypropylene, or standard polyester fail drastically under thermal loads surpassing 130°C. Polyimide (PI) film tape—popularly referenced by the market name Kapton® equivalent—maintains supreme structural, physical, and dielectric stability across a phenomenal operating spectrum between -269°C (-452°F) to +260°C (500°F), sustaining peak operational excursions exceeding 400°C for intermittent soldering processes.
Provides critical high-breakdown voltage threshold surpassing 6,500V to 8,000V across film thicknesses of 1 mil (0.025mm) and 2 mil (0.050mm), mitigating flashover in tight electronics assemblies.
Continuous Class H (180°C) and Class C (220°C+) operation without embrittlement, dielectric puncture, or shrinkage during lead-free wave soldering and reflow processes.
Our proprietary thermal platinum catalyst silicone formulation secures controlled peel adhesion (5.5 - 7.5 N/25mm) ensuring complete removal without leaving gummy siloxane residue on gold pads.
The strategic synergy of raw polymer precursor synthesis, vertical coating integration, and unmatched Pearl River Delta supply chains.
Zhuhai Huayuan controls costs directly from chemical monomers (PMDA and ODA) down to precision roll conversion. By eliminating three tiers of trading intermediaries, procurement teams capture 35% to 50% cost reductions against Western brand counterparts while exceeding ASTM test benchmarks.
Our Zhuhai & Zhongshan facilities house 10,000-class and 1,000-class dust-free coating chambers. High-precision comma coating heads ensure caliper tolerance within ±0.002mm, eradicating micro-voids, pinholes, and orange-peel adhesive defects that cause electrical breakdowns.
Situated in the Greater Bay Area next to Shenzhen and Hong Kong deep-water ports, we turn log rolls into custom slitted coils (down to 1.5mm widths) with lead times under 7 business days, providing flexible logistics pathways for European, American, and Asian sea/air freight corridors.
From aerospace satellite harnesses to the high-throughput production lines of gigafactories, discover how polyimide tape underpins modern electrification.
Protects gold fingers, edge connectors, and surface-mount pads against liquid solder alloys exceeding 260°C. Anti-static ESD-treated polyimide versions eliminate electrostatic discharge risks that jeopardize sensitive IC silicon substrates.
Acts as an essential thermal and dielectric partition between anode and cathode tabs in cylindrical (18650, 21700, 4680), pouch, and prismatic cells. Resists aggressive organic carbonate electrolyte solvents.
Serving high-frequency traction transformers, wind turbines, and Class H motor windings. Its minimal thickness delivers maximum magnetic flux density within tightly constrained copper coil spaces.
Forms the universal heated bed tape (build plate surface) for ABS, PLA, and high-temp filaments. Also serves as the premier heat-transfer tape for high-pressure sublimation dye processes on ceramics and textiles.
Integrates with flexible copper clad laminates (FCCL) and ultra-thin mobile camera assemblies. High dimensional stability ensures no micro-creasing occurs under dynamic multi-axis bending stresses.
Masks critical grounding threads, machined bores, and mating contact faces on die-cast aluminum and steel housings subjected to electrostatic thermoset cure cycles at 200°C–230°C.

Ensure factory accountability and compliance when securing OEM supply contracts for specialized tapes.
Demand accelerated thermal aging data (180°C for 72 hours). Inferior manufacturers cut costs by diluting silicone adhesives with low-grade solvents, triggering rapid adhesive transfer, embrittlement, and adhesive splitting upon unmasking.
Inspect slitting machine tension control. Our Italian-engineered high-precision razor and rotary shear slitters eliminate microscopic edge burrs and core telescoping, ensuring continuous automated high-speed peel unwinding without snaps.
Every jumbo batch manufactured by Huayuan undergoes rigorous GC-MS testing to guarantee total absence of restricted halogens, PFOS/PFOA, heavy metals, and organotin compounds in conformance with EU RoHS 2.0 and REACH 235 SVHC lists.
Comprehensive engineering clarifications for converters, QA managers, and international supply chain leaders.
