Precision-engineered electrical insulation, thermal masking, and structural double-sided adhesives configured for high-throughput global converting lines and OEM assembly.
High-temperature pressure-sensitive tapes (PSA) operate at the intersection of thermal thermodynamics, dielectric barrier defense, and surface energy mechanics. Selecting the correct carrier-adhesive composite dictates process reliability.
Polyimide (commonly specified as Kapton-equivalent) represents the peak of thermal endurance for wave soldering, powder coating masking, and lithium-ion pouch cell protection. PI preserves extreme tensile modulus and dielectric isolation across continuous operational thresholds from -70°C up to +260°C (with peaks handling 300°C for short duration reflow cycles).
Biaxially oriented polyethylene terephthalate (PET) films engineered for Class B thermal insulation (up to 130°C/155°C). Mylar tape provides exceptional tensile rigidity, tear propagation resistance, and cost-efficiency. Frequently combined with fire-retardant thermosetting acrylics for winding phase barriers, transformers, relays, and motor bobbin coil wraps.
Woven alkali-free electrical fiberglass fabrics coated with silicone or thermosetting rubber systems, serving Class H (180°C) and Class N (200°C) demands. Directly replaces 3M 69 tape. Provides immense mechanical tensile capacity, non-corrosive inertness, and extreme absorption for solvent-borne dipping varnishes in traction motors and arc furnaces.
International electronics brands and global industrial converters face relentless margin pressure. Sourcing directly from certified Zhuhai and Zhongshan adhesive plants delivers distinct systemic advantages.
Our production ecosystem eliminates third-party toll coating markups. Synthetic silicone blending, acrylic polymerization, release liner siliconization, and high-speed precision coating lines occur under unified ISO 9001 supervision.
Optical grade coatings and ultra-thin electrical masking tapes require dust-free environments. Our enclosed coating lines utilize automated laser web-inspection systems to prevent pinholes, adhesive fish-eyes, and particulate entrapment.
Whether your enterprise requires 1,280mm master jumbo rolls for automated slitting facilities, log rolls, or custom-slit narrow spools (down to 1.5mm ±0.1mm tolerance), our CNC slitting and rotary die-cutting plant adapts instantly.
Headquartered directly adjacent to the Hong Kong-Zhuhai-Macao economic corridor, we ensure cross-border bonded dispatch within 48 hours, facilitating air-freight express qualification samples and full container maritime dispatch via Shenzhen and Hong Kong.
Standardized test data derived from ASTM D1000, ASTM D149, and PSTC-101. Reference these parameters for procurement drawings and production line qualifications.

Risk mitigation is paramount for tier-one automotive, aerospace, and consumer technology procurement teams. Here is how our Zhuhai plant satisfies international regulatory frameworks.
All raw polymer resins, silicone crosslinkers, plasticizers, and pigment masterbatches undergo quarterly SGS and TÜV testing. Every wholesale shipment includes full lot-traceable declarations verifying lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr VI), PBBs, PBDEs, and phthalate concentrations remain safely below limits (0.1% / 1000 ppm).
For hermetically sealed aerospace sensors, lidar modules, and cleanroom vacuum environments, standard silicone adhesives can release volatile siloxanes that condense on delicate optical prisms. We manufacture ultra-low outgassing formulations and halogen-free fire-retardant tapes complying with IEC 61249-2-21 standards (Cl <900ppm, Br <900ppm, Total Halogens <1500ppm).
Every jumbo master log is laser-engraved with batch barcodes indexing coat weight (±1.5 g/m²), drying oven curing temperature curves, and solvent dwell retention time. Statistical process control metrics ensure Cpk ≥ 1.33 across log tensile, peel holding power, and dielectric withstand tests, ensuring zero field failures for end-use assemblies.
From electric mobility megatrends to microelectronics miniaturization, high-temperature adhesives must perform under compound mechanical, chemical, and thermal stress.
Modern prismatic and cylindrical 4680 battery modules run under aggressive thermal cycles. Polyimide and PET double-sided tapes function as dielectric insulation barriers between adjacent aluminum casings and copper busbars, withstanding electrolyte immersion without delamination or dielectric breakdown during runaway thermal events.
As surface-mount technology (SMT) transitions toward lead-free solder pastes requiring peak reflow temperatures exceeding 255°C, standard masking tapes leave chemical silicone shadows or peel off premature. Our specially formulated amber polyimide tapes maintain clean peel separation without leaving siloxane residue on micro-pitch BGA gold pads.
High-speed industrial thermal transfer and electrostatic powder coating require tapes that withstand 200°C cure ovens for 30 minutes without edge-lifting. PET green masking tapes featuring specialized silicone formulations provide razor-sharp paint demarcations and strip effortlessly in one piece without tearing.
