Direct supply for global converters, OEM brand assemblers, and electronics manufacturing contractors.
Bridging chemical resistance, thermal stability up to 220°C, and clean-peel demasking characteristics.
Unlike standard acrylic resins that degrade under thermal cycles, our silicone adhesive is formulated from polydimethylsiloxane networks cross-linked via platinum catalysis. This creates a thermo-stable pressure-sensitive barrier capable of enduring 200°C–220°C baking schedules without charring, edge flagging, or leave-behind adhesive transfer.
Our carrier film uses corona-treated, optical-grade polyethylene terephthalate (PET). Biaxial stretching delivers isotropic mechanical strength, exceptional puncture resistance, and tensile modulus exceeding 180 MPa. It prevents elongation drift during continuous high-speed roll unwinding and precision automatic die-cut placement.
To eliminate delamination between backing film and adhesive coating during thermal demasking, a specialized chemical coupling primer is applied inline. This anchors the silicone matrix permanently to the PET backing, ensuring 100% ghost-free removal from polished gold fingers, aluminum alloys, and FR4 surfaces.

Dual production bases in Zhuhai and Zhongshan with direct international clearing from Hong Kong.
From monomer polymerization and silicone formulation synthesis to cleanroom web coating, rewinding, and precision rotary die-cutting, 100% of processing remains in-house, compressing standard lead times by 35%.
Operating under certified quality standards since 2013. Every master jumbo roll carries a unique QR-coded tracking profile, detailing solvent cure temperature profiles, coating caliper data, and lot retention peel checks.
Proximity to Shenzhen, Guangzhou, and Hong Kong ports enables same-day container stuffing and direct intermodal shipping, bypassing port bottlenecks and delivering reliably to European, American, and Asian converters.
Full spectrum compliance: verified SGS lab testing reports, UL94 flame-retardant designations, and strict zero-halogen / RoHS directive alignments required by major European automotive Tier-1 suppliers.
Addressing supply stability, regulatory validation, and customized technical requirements in 2026.
Multinational industrial groups are moving away from sole-source reliance on legacy multinational suppliers. Huayuan provides qualified drop-in functional equivalents for established brands (such as 3M 8992 and tesa 50600), delivering identical technical performance at a 25–40% total procurement cost saving.
The exponential expansion of prismatic and cylindrical lithium battery assembly drives strict demand for electrolyte-resistant, high-dielectric PET barrier tapes that resist swelling and chemical decomposition when exposed to corrosive solvents (DMC, EC, and LiPF6).
Converters require consistent unwind force tension, low static generation during rapid peel, and burr-free rotary slit edges. We utilize precision German slitting machines to prevent edge nicks, web tears, or automated assembly line jams down to ±0.2 mm tolerances.
Field-proven performance across demanding surface preparation and electronic manufacturing.
Masks critical mounting threads, mating flanges, and grounding studs during high-bake thermal curing schedules up to 200°C. Resists paint seepage and leaves razor-sharp paint separation lines upon removal.
Protects edge connectors and gold fingers from severe bath chemistry during PCB etching and electroplating. Resists aggressive acid/alkali drag-out and prevents undercut lifting along circuit traces.
Provides flash masking and high-temperature vacuum bagging hold-down during carbon fiber and composite curing in aerospace and marine autoclaves, pulling cleanly from cured epoxy matrices.
Silicone adhesives stick aggressively to low surface energy silicone release papers and films, making this the standard formulation for splicing rolls in high-speed label converting lines.
Clear, direct engineering answers for procurement managers, chemical engineers, and import buyers.
Our formulation incorporates cross-linked, high-molecular-weight organopolysiloxane cured at strictly regulated thermal profiles in dust-free ovens. We coat our PET substrate with an inline chemical bonding primer that permanently anchors the silicone adhesive to the backing film. This ensures the cohesive strength of the adhesive and its anchorage to the carrier film consistently exceed its peel adhesion to the metal or electronic substrate, guaranteeing 100% residue-free peeling.
Standard master formulations feature a total caliper of 2.0 mil (0.05 mm) to 3.5 mil (0.09 mm), consisting of 1.0–2.0 mil PET base film and 1.0–1.5 mil cured silicone adhesive. For custom orders, we provide precision slitting from narrow 3 mm ribbon formats up to 1000 mm master jumbo rolls. Our high-precision slitting tolerances are held strictly within ±0.2 mm.
While both commonly feature silicone adhesives for clean removal, their base carriers differ significantly. Polyester (PET) tape is rated for continuous exposure up to 200°C–220°C, making it the most cost-effective choice for industrial powder coating, e-coating, and electroplating masking. Polyimide film can withstand extreme temperatures up to 260°C–300°C and provides superior dimensional stability during direct molten wave soldering and SMT reflow baths, but comes at a higher unit cost.
Every commercial production batch is accompanied by comprehensive quality and compliance documentation, including a Certificate of Analysis (COA), full RoHS (EU Directive 2011/65/EU and its amendment 2015/863) compliance declarations, REACH SVHC screening reports, and halogen-free test records conducted by independent testing authorities like SGS.
Yes. In addition to continuous rolls, our Zhongshan facility houses high-speed rotary die-cutting systems. We produce custom precision shapes, pull-tabs, circles, and kiss-cut configurations mounted on transparent fluorosilicone release liners or PET backing liners, specifically engineered for zero-static automated pick-and-place robotics.
We provide free sample rolls and standard die-cut evaluation packs for qualified engineering and procurement audits.
