Surface Compatibility & Applications
HVAC Ducts: Seals seams and joints on rigid sheet metal and flexible air ducts, eliminating forced-air leakage and energy loss.
FSK Insulation Boards: Joins glass wool and rock wool duct wrap facings with a continuous vapor-tight barrier to prevent condensation accumulation.
Thermal Piping: Wraps hot and chilled water supply lines to stop surface sweating and prevent Corrosion Under Insulation (CUI).
Commercial Roofing: Bonds rigid PIR/PUR insulation boards and aluminum-clad membrane overlaps to maintain seal integrity under direct weather exposure.
Substrate Compatibility: Suitable for galvanized steel, aluminum, glass fiber, PUR/PIR insulation and selected plastics. Surface preparation requirements depend on substrate condition.
Tape Construction
Backing Options
Dead-soft plain aluminum foil or FSK tri-directional scrim with tensile strength ≥100 N/25mm for heavy-duty mechanical loads.
Silicone PE Kraft Liner
High-release liner enables rapid manual peeling without tearing, speeding up installation.
Bonding Performance
High-Shear Solvent Acrylic
Resists plasticizer migration and thermal degradation during continuous 120°C operating cycles.
Cold-Weather Formulation
Achieves instant tack on sub-zero substrates down to -30°C, eliminating winter application delays and pre-heating requirements.
180° Peel Adhesion (ASTM D3330)
Delivers ≥12 N/25mm bond strength on bare stainless steel within 20 minutes of application.
OEM, Customization & Private Label
Custom Sizing & Widths
Precision slitting available from 10 mm to 1200 mm widths and customized roll lengths up to 100 m.
Core Branding
1-color or 2-color screen printing on inner paper cores for custom logos, part numbers, and error-free jobsite identification.
Retail-Ready Packaging
Individual roll shrink-wrapping with custom branded labels, barcodes, and hang tags for immediate distribution.
Manufacturing Process
Raw Material Verification: We test pure aluminum foil rolls per ASTM B209 standards. Micrometer inspections verify foil thickness before adhesive application, preventing weak spots and tear-outs on site.
Adhesive Formulation: Adhesive blends are tailored for HVAC ducts and cold-storage seals. The formula prevents glue degradation and edge-lifting under constant high humidity.
Precision Coating & Curing: Inline coating controls adhesive weight within ±1.5 GSM. This uniform thickness ensures steady peel strength without edge-bleeding or sticky residue during unwinding.
FSK Lamination: Aluminum foil, tri-directional fiberglass scrim, and Kraft paper are thermally bonded. The reinforced layer provides tensile strength to resist accidental job-site punctures.
Slitting & Traceability: Jumbo rolls are precision-slit within ±0.5 mm tolerance. Each roll carries a batch ID, enabling full material traceability back to the raw coil within 24 hours.
FAQ
Q: Is this tape compliant with REACH and RoHS for EU import?
A: Yes, the adhesive and aluminum backing comply with REACH (EC 1907/2006) and RoHS Directive 2011/65/EU, with SGS test reports available upon request.
Q: What is the minimum order quantity and standard lead time?
A: MOQ starts at 500 rolls for standard widths, with a production lead time of 12–15 days after deposit confirmation, separate from sample dispatch.
Q: Does the FSK scrim backing have a certified tear resistance rating for mechanical fastening applications?
A: The FSK tri-directional scrim resists tearing under direct fastener load, backed by a certified tensile strength of ≥100 N/25mm as already tested per production batch.
Q: Can buyers arrange third-party inspection before mass shipment?
A: Yes, an on-site or video-based third-party inspection (SGS/BV) can be arranged at the buyer's cost before container loading.
Q: How long does the tape retain its rated adhesion performance in storage?
A: Unopened rolls retain full peel and shear performance for 12 months when stored at 20°C (68°F) and 50% relative humidity.
