Glass Cloth Tape Substitute for 3M 69 Tape - High Heat Resistance for Insulation Applications
Explore Product Specifications
Explore our core product series engineered in Zhuhai and Zhongshan dust-free coating facilities. Each grade supports rigorous OEM batch tolerances, custom slitting, and private labeling.
A comprehensive examination of antistatic surface resistivity, triboelectric prevention, and solvent-free cross-linked silicone adhesives in modern cleanroom environments.
In high-density electronics and automated SMT assembly, standard insulating films generate destructive static potentials. Ordinary polyimide tape, when unwound from its roll or stripped from a PCB gold finger, creates triboelectric charges exceeding 1,500V to 3,000V. This level poses an immediate risk of gate oxide breakdown in sub-5nm semiconductors, MEMS sensors, and sensitive optical components.
Wholesale ESD Polyimide Tape (engineered with DuPont Kapton® equivalent aromatic polyimide film) resolves this vulnerability. By impregnating conductive polymer matrix networks or depositing nanometer-thin carbon antistatic coatings onto both the top film layer and the silicone adhesive matrix, Huayuan eliminates electrostatic generation right at the source.
| Performance Characteristic | Standard Polyimide (Kapton) Tape | Huayuan Anti-Static (ESD) Polyimide Tape | Engineering Benefit |
|---|---|---|---|
| Surface Resistivity (Carrier) | > 1.0 × 1012 Ω/sq (Insulative) | 1.0 × 106 – 1.0 × 109 Ω/sq (Static Dissipative) | Prevents charge accumulation during robotic pick-and-place. |
| Peeling Triboelectric Voltage | > 2,500 Volts (Unwinding) | < 50 Volts (ESD Safe Peak) | Complies with ANSI/ESD S20.20 and IEC 61340 standards. |
| Maximum Working Temperature | 260°C (500°F) for 30 min | 260°C – 300°C peak wave-solder | Leaves zero adhesive transfer or blistering on circuit pads. |
| Adhesive Peel Adhesion (N/25mm) | 5.5 – 6.5 N/25mm | 5.0 – 6.0 N/25mm (Formulated) | Balanced tack allows smooth peel without mechanical board stress. |
| Dielectric Breakdown Voltage | 6,500 Volts | 5,500 – 6,000 Volts | Maintains Class H electrical insulation across transformer layers. |
How Zhuhai Huayuan Electronics integrates automated coating loops, imported slitting lines, and Greater Bay Area logistics to reduce overall cost of ownership.
Static elimination relies on microscopic purity. Our dual-base plants operate enclosed, dust-free drying and curing tunnels where micro-voids, pinholes, and airborne carbon impurities are stopped before adhesive bonding takes place.
Real-time optical infrared thickness scanners measure backing substrate and adhesive coat weights to within ±0.002mm tolerances, ensuring unwinding torque consistency across log rolls and master rolls.
Equipped with high-precision imported multi-blade slitters, Huayuan delivers widths starting from 2mm up to 1000mm. We manufacture rotary die-cut masks, discs, and pull-tab sheets tailored to your exact bill of materials (BOM).
Located next to deep-water ports in Shenzhen, Hong Kong, and Guangzhou, our supply network provides international buyers with CIF, FOB, and DDP shipping flexibility, expediting customs clearance worldwide.
From cleanroom SMT reflow lines to EV powertrain cell containment, discover where industrial buyers specify our anti-static adhesive tapes.
Protects gold contacts and sensitive micro-vias during wave soldering and hot-air levelling (HASL). Antistatic properties prevent dust attraction and remove ESD risks when peeling the tape after 260°C thermal exposure.
Used for prismatic, pouch, and cylindrical cell core wrapping, tab insulation, and module busbar masking. Provides chemical resistance against harsh carbonate electrolytes and safeguards battery packs against thermal runaway.
Applied to wafer protection stages and lead-frame fixation during epoxy encapsulation. Ultra-low outgassing under deep vacuum ensures wire-bonding surfaces stay free of chemical film contamination.
Delivers Class H electrical insulation, outstanding radiation resistance, and low flammability (UL 94V-0 compliant). Protects avionics and military wiring bundles across extreme temperature environments (-70°C to +260°C).
