Jiubin JB-120 Adhesive Tape Peel Strength Tester

Overview

The Jiubin JB-120 Adhesive Tape Peel Strength Tester is an electronically actuated universal testing machine engineered for high-reproducibility mechanical characterization of pressure-sensitive adhesives (PSAs), tapes, labels, laminates, and coated substrates. It operates on the principle of controlled tensile separation—applying precisely regulated axial force to detach a bonded interface at standardized geometries (90°, 180°, or roller peel configurations)—and measures the force required per unit width to sustain steady-state debonding. This instrument conforms to core ISO 8510-2, ASTM D3330, ASTM D903, PSTC-101, and GB/T 2792 test methodologies, delivering traceable, repeatable peel strength data essential for QC release, formulation development, and regulatory documentation in adhesive manufacturing, packaging, medical device assembly, and electronics bonding applications.

Key Features

• High-fidelity force measurement system with full-scale accuracy of ±1% (±0.5% optional), calibrated across 0.4–100% FS without range switching—ensuring linearity and stability across low-force tape peel and high-load composite delamination tests.
• Digitally controlled AC servo motor drive with closed-loop speed regulation, enabling displacement rate control from 0.001 to 500 mm/min—critical for matching viscoelastic response requirements of acrylic, rubber-based, and silicone PSAs.
• Triple closed-loop control architecture supporting simultaneous or independent regulation of load, displacement, and strain—enabling advanced protocols such as creep-peel, stress-relaxation peel, and constant-strain-rate detachment.
• Modular fixture platform compatible with standardized peel jigs (ISO 29862-compliant 90°/180° peel blocks, ASTM D3330 roller assemblies), tensile grips, compression platens, bend fixtures, and custom-engineered tooling for specialty substrates (e.g., flexible printed circuits, hydrogel films).
• Integrated safety architecture including hardware-limit switches, real-time overload cutoff (110% FS), overcurrent/overvoltage monitoring, and front-panel emergency stop—fully compliant with IEC 61000-6-2 EMC and ISO 12100 risk assessment frameworks.

Sample Compatibility & Compliance

The JB-120 accommodates a broad spectrum of sample geometries and material classes: single- and double-coated tapes (acrylic, rubber, silicone), transfer adhesives, medical tapes (e.g., hypoallergenic acrylics), packaging laminates (PET/Alu/PE), automotive trim foams, and thin-film electronics substrates. Its mechanical design supports specimen widths up to 50 mm (standard) with optional wider fixtures. All test procedures align with internationally recognized standards—including ISO 29862 (peel adhesion), ASTM D1876 (T-peel), ASTM D6252 (loop tack), and GB/T 7122 (high-strength adhesive shear)—and support audit-ready reporting for GLP, GMP, and FDA 21 CFR Part 11 environments when paired with validated software modules.

Software & Data Management

Control and analysis are performed via Jiubin’s WinTest Pro v4.x software suite—a Windows-based application featuring real-time multi-curve plotting (force vs. displacement, peel force vs. time, energy integral), automatic peak detection, plateau averaging (per ASTM D3330 §7.3), and statistical batch reporting (mean, SD, CV%, min/max). Raw data export is supported in CSV, Excel, and XML formats; PDF report templates include operator ID, calibration certificate references, environmental conditions (optional sensor integration), and digital signature fields. The software architecture supports user-level access controls, electronic audit trails, and revision-locked method files—meeting baseline requirements for ISO/IEC 17025 laboratories and pharmaceutical quality systems.

Applications

• Quantification of 90° and 180° peel adhesion strength for release liner validation and backing film selection.
• Comparative evaluation of aging effects (thermal, UV, humidity) on PSA bond durability using accelerated chamber-integrated test sequences.
• Quality conformance testing of medical-grade tapes against USP particulate limits and ISO 10993-5 cytotoxicity prerequisites.
• Development of low-tack repositionable adhesives through controlled low-speed peel profiling (0.01–10 mm/min).
• Mechanical screening of structural tapes used in EV battery module bonding under combined thermal–mechanical loading profiles.

FAQ

What peel angles does the JB-120 support natively?
The system includes certified 90° and 180° peel fixtures per ISO 29862 and ASTM D3330, plus a roller peel assembly compliant with ASTM D1876. Custom angular fixtures (e.g., 45°, 135°) are available upon request.
Can the JB-120 perform shear adhesion tests?
Yes—using optional lap-shear fixtures and ASTM D1002/D3163-compliant alignment tooling, it delivers shear strength and cohesive failure mode analysis for structural adhesives.
Is calibration traceability provided with the instrument?
Each unit ships with a factory calibration certificate traceable to CNAS-accredited national standards (GB/T 5224, JJG 475); on-site recalibration services and ISO/IEC 17025-certified external calibration are available.
Does the system meet FDA 21 CFR Part 11 requirements?
Out-of-the-box compliance requires WinTest Pro v4.x with enabled audit trail, electronic signatures, and role-based permissions—validated per laboratory SOP and documented in the instrument’s IQ/OQ package.
What is the maximum specimen thickness the standard grips can accommodate?
Standard pneumatic or wedge-action grips accept specimens up to 15 mm thick; high-clearance fixtures for foam or corrugated substrates are offered as accessories.
