View Product SpecificationsKapton roll tape—synthesized from polyimide (PI) film through aromatic dianhydride and diamine condensation (PMDA/ODA)—remains the undisputed gold standard in high-temperature electrical insulation, aerospace avionics, and semiconductor packaging. Originally commercialized by DuPont, polyimide's distinct molecular structure, characterized by aromatic rings and imide linkages, endows it with exceptional thermodynamic stability, near-zero outgassing under ultra-high vacuum (UHV), and persistent mechanical integrity from -269°C up to +400°C.
In the contemporary global landscape, Chinese precision tape manufacturers have closed the technological gap through domestic polymer synthesis, precision biaxial stretching, and cleanroom solvent-based silicone coating. Zhuhai Huayuan Electronics Co., Ltd. (operating since 2007) represents this structural elevation. Leveraging dual production hubs in the Nanping Science and Technology Park (Zhuhai) and Tanzhou Town (Zhongshan), alongside our Hong Kong international interface, we engineer Kapton rolls that meet or exceed ASTM D5213, UL 510, and IPC-TM-650 specifications.
The global shift toward Chinese polyimide suppliers is not merely cost-arbitrage; it is driven by vertical integration. Direct access to domestic polyimide resin, automated micro-gravure coating lines, cleanroom class 1,000 slitting, and localized die-cutting allow China-based plants to offer custom master log rolls (up to 1280mm width) and slit widths as narrow as 1.5mm within 3-5 days lead time, with full lot-traceability and RoHS/REACH compliance.
Comprehensive engineering benchmarks comparing electrical, physical, and chemical resistance parameters across core substrate architectures.
| Substrate Material | Typical Base Carrier Thickness | Adhesive Chemistry | Dielectric Breakdown Voltage | Continuous Operating Temp | Residue-Free Removal | Common Applications |
|---|---|---|---|---|---|---|
| Polyimide (Kapton / PI) | 0.025mm – 0.075mm | Cross-linked Silicone / Acrylic | 5.0 – 7.5 kV | -40°C to +260°C (300°C Peak) | Zero Residue | PCB Wave Soldering, EV Battery Tab Insulation, Aerospace |
| Polyester (PET Mylar) | 0.025mm – 0.050mm | Thermosetting Acrylic | 4.0 – 5.5 kV | Up to 130°C (Class B) | Good | Transformer Coils, Motor Phase Insulation, Outer Wrapping |
| Woven Glass Cloth | 0.120mm – 0.180mm | High-Performance Silicone | 2.5 – 3.5 kV | Up to 200°C (Class H) | Moderate | Traction Motors, Induction Furnaces, Heavy Cable Splice |
| Copper Foil (EMI) | 0.018mm – 0.050mm | Conductive Acrylic | Conductive (0.05 Ω) | -20°C to +120°C | Permanent Bond | EMI/RFI Enclosure Shielding, Slug Barrier, Stained Glass |
| VHB Acrylic Foam | 0.5mm – 2.0mm | Viscoelastic Acrylic Core | N/A (Structural) | -35°C to +150°C | Permanent Structural | Automotive Trim, Electronic Bezel Bonding, Panel Mounting |
From microelectronics surface-mount technology to mega-watt electric mobility platforms, our polyimide film systems provide unwavering structural and dielectric integrity.
During selective wave soldering and reflow processes reaching 260°C–280°C, printed circuit boards expose delicate gold contacts to aggressive flux and molten solder. Huayuan's HY200 series Polyimide tape acts as an impermeable chemical and thermal barrier, peeling off cleanly post-reflow with zero silicone ghosting or adhesive transfer.
Modern cylindrical (4680, 21700) and prismatic EV battery cells demand ultra-thin insulation barriers (under 50μm) to maximize volumetric energy density. Our polyimide tapes resist corrosive electrolyte immersion (DMC/EMC solvents) while preventing puncture, dielectric flashover, and thermal propagation during fast-charging cycles.
Under low-Earth-orbit radiation, atomic oxygen bombardment, and severe thermal cycles (-150°C to +200°C), Kapton tape provides high cut-through resistance and low outgassing (CVCM < 0.1%, TML < 1.0%). Huayuan supplies custom slit rolls tailored for high-density space-grade harness wrapping and cryogenic liquid fuel lines.
With precise dimensional stability and isotropic thermal conductivity, Kapton roll tape serves as the premier build surface for ABS, PLA, and high-temp PEEK filaments. It prevents warping during thermal ramp-ups and functions as an essential heat transfer masking tape in heat press sublimation processes.
Meeting IEC 60085 Class H (180°C) and Class C (220°C+) operating demands, our polyimide film combined with thermosetting silicone adhesive provides superior mechanical holding force for copper coil winding, inter-phase barrier wrapping, and core insulation against high-voltage surges.
As semiconductor lithography nodes shrink and 800V silicon carbide (SiC) traction inverters become mainstream in automotive platforms, tape manufacturers face demanding chemical and rheological challenges. Huayuan's R&D engineering divisions in Guangdong are currently spearheading four pivotal technological evolutions:
Nearly two decades of proprietary pressure-sensitive adhesive synthesis, rigorous ISO quality frameworks, and advanced die-cutting conversion capabilities.
Operating an audited ISO 9001 quality management framework since 2013. Every master jumbo roll undergoes inline optical defect inspection, automated dry coating weight validation, and release liner peel angle consistency tests.
Formally recognized as a High-Tech Enterprise in 2017 and awarded the prestigious Guangdong Province "Specialized, Refined, Distinctive, and Innovative" SME distinction in 2023, reflecting continuous chemical IP innovation.
Equipped with high-speed rotary die-cutters, CCD visual alignment slitting equipment, and Class 1,000 dust-free converting cleanrooms capable of delivering kiss-cut rolls, custom pull-tabs, and private-label blister packaging within 24–48 hours.
In-depth technical guidance addressing thermal parameters, adhesive residue, customized slitting, and international compliance standards.
Comprehensive portfolio of industrial double-sided, nano acrylic gel, thermal conductive, and heavy-duty VHB bonding tapes manufactured to ISO 9001 standards.
