Direct supply from Zhuhai & Zhongshan dust-free coating facilities. Engineered for microelectronics, EV battery pack assembly, and high-temp masking.
An in-depth perspective on why polyimide (PI) films with cross-linked silicone adhesives remain non-negotiable across aerospace, EV battery chemistry, and modern microelectronics packaging.
Kapton Polyimide Plastic Tape utilizes aromatic polyimide backings that preserve mechanical modulus across cryogenic temperatures (-269°C) up to operational limits exceeding +260°C (+400°C for short bursts). Coupled with silicone pressure-sensitive adhesives, it prevents dielectric punch-through under high-voltage transformer stress.
During SMT wave soldering and reflow processes, lead-free solders demand peak thermal cycles around 250°C. China Kapton polyimide tape guarantees immaculate gold-finger masking without adhesive transfer, ghosting, or carbonization, mitigating short-circuit vulnerabilities in fine-pitch IC arrays.
As EV battery cells migrate toward higher energy densities, internal shorts present catastrophic fire risks. Polyimide tapes are strictly specified for battery tab wrapping, busbar thermal barriers, and pouch cell edge-sealing owing to exceptional electrolyte resistance and non-flammability.
Operating from Zhuhai and Zhongshan with ISO 9001 certified cleanrooms, Huayuan provides high-precision coating, custom slitting, and complete die-cut reliability.
Dual production bases house automated, dust-free multi-zone drying tunnels that regulate web tension and coating weights within ±1.5 µm tolerances, ensuring flawless tack and thickness stability.
Equipped with micro-knife high-speed slitting units, we produce clean, burr-free roll edges from ultra-narrow widths (2mm) up to 1000mm jumbo master rolls without air entrapment or edge telescoping.
Converting capabilities established since 2013 allow precision rotary and flatbed die-cutting into discs, custom-shaped gaskets, tab pull-tabs, and kiss-cut sheets for direct automated production placement.
Supported by Huayuan International Technology (Hong Kong), orders benefit from prompt multimodal customs handling and rapid maritime dispatch via Shenzhen and Hong Kong deep-water container ports.
How global high-reliability manufacturers deploy Kapton polyimide and high-performance adhesives across diverse production lines.
Thin 1 mil (25µm) polyimide tapes with controlled release systems act as sacrificial carriers during wafer back-grinding and chip-on-film (COF) bonding, eliminating static discharge (ESD) through optional anti-static coatings.
Polyimide tape provides weight-saving thermal and radiation shielding for commercial aircraft and orbital satellites. Its exceptional self-extinguishing flame retardancy prevents harness-to-frame short circuits.
As electric vehicles adopt 800V architectures, IGBT modules generate immense local thermal loads. Custom die-cut polyimide films provide puncture-proof insulation barriers between copper busbars and chassis ground plates.
