ChemInstruments AR-2000 Adhesion and Peel Testing Instrument

Overview

The ChemInstruments AR-2000 Adhesion and Peel Testing Instrument is a precision-engineered mechanical testing system designed for quantitative evaluation of pressure-sensitive adhesive (PSA) performance under standardized laboratory and production-line conditions. Based on the fundamental principle of controlled-force tensile separation, the AR-2000 applies calibrated linear motion to peel a bonded substrate at defined angles (90° or 180°) and speeds (1–1200 ipm), measuring the instantaneous and average force required to separate the adhesive interface. This methodology directly supports gravimetric and dynamic force analysis per internationally recognized test protocols—including PSTC, ASTM, TLMI, AFERA, and FINAT—ensuring traceable, repeatable, and audit-ready results across global quality assurance workflows.

Key Features

• 5.7-inch high-resolution color touchscreen interface enabling fully standalone operation—no external PC required for test initiation, parameter configuration, or real-time curve visualization.
• Ruggedized industrial enclosure rated for continuous operation in ambient manufacturing environments, including temperature fluctuations (0–70 °C) and moderate particulate exposure.
• Digital servo-controlled drive system with optical encoder feedback ensures precise velocity regulation across the full speed range (±0.2% linearity), critical for compliance with time-dependent standards such as PSTC-101 Method E (low-speed creep) and ASTM D3330 Method A (constant-rate peel).
• Modular load cell architecture supporting interchangeable sensors (2, 5, 10, or 25 lbf full scale), each calibrated to ±0.1% of reading, allowing optimal resolution selection based on substrate bond strength and application class.
• Adjustable peel angle fixture with mechanical detents at 90° and 180°, engineered to maintain angular fidelity within ±0.5° throughout test duration—essential for distinguishing cohesive vs. interfacial failure modes.
• USB 2.0 host port for direct firmware updates and bidirectional data transfer to the EZ-Date™ software platform, supporting CSV export, statistical summary generation (mean, SD, CV%), and graphical overlay of multiple test runs.

Sample Compatibility & Compliance

The AR-2000 accommodates specimens from 0.5 inches (12.7 mm) to 12 inches (305 mm) in length, compatible with standard PSA tape widths up to 2 inches (50.8 mm). Its modular grip design accepts both rigid backing materials (e.g., PET, aluminum foil, stainless steel) and flexible substrates (e.g., polyolefin films, paper liners, release-coated silicones). The instrument is validated for conformance with all major international adhesion testing frameworks: PSTC-101 (Methods A–F), PSTC-4 (Loop Tack), PSTC-15 (Quick Stick), PSTC-55 (Shear Holding Power); ASTM D3330 (Peel Adhesion of Pressure-Sensitive Tapes); TLMI L-IA1 (Roll-to-Roll 90° Peel), L-IA2 (180° Peel), L-IA3 (Static Shear); AFERA 4001 R11 (Peel Adhesion at 90°); and FINAT FTM 1–6 (Peel, Shear, Tack), FTM 10 (Low-Speed Peel), FTM 11 (High-Speed Peel). All mechanical and electronic subsystems are designed to meet ISO/IEC 17025 calibration traceability requirements when operated within certified laboratory environments.

Software & Data Management

EZ-Date™ is a Windows-based data acquisition and reporting suite developed specifically for ChemInstruments peel testers. It provides GLP-compliant audit trails—including user login timestamps, parameter change logs, and raw force/time dataset versioning—fully aligned with FDA 21 CFR Part 11 electronic record requirements when deployed with appropriate system validation documentation. The software enables automated pass/fail threshold evaluation against predefined specification limits, batch-level statistical process control (SPC) charting (X̄/R, Cpk), and export of formatted reports compliant with internal QA templates or external customer submission formats (e.g., AIAG PPAP Level 3). Raw .csv files retain millisecond-sampled force and displacement metadata, permitting post-hoc analysis of peak load onset, plateau stability, and failure event timing.

Applications

• Quality control of pressure-sensitive tapes, labels, medical transdermal patches, and protective films during incoming inspection and final release testing.
• R&D evaluation of new adhesive formulations—including acrylics, rubbers, silicones, and hybrid dispersions—across variable peel rates, temperatures, and substrate combinations.
• Process validation of coating lines, slitting operations, and die-cutting stations where adhesive integrity must be verified after mechanical stress exposure.
• Regulatory dossier preparation for FDA 510(k), CE marking, or ISO 13485-certified medical device packaging systems requiring documented peel performance evidence.
• Supplier qualification audits where third-party laboratories require instrument traceability to NIST-traceable force standards and documented uncertainty budgets.

FAQ

Does the AR-2000 support custom test protocols beyond listed standards?

Yes—the touchscreen interface allows manual entry of non-standard peel angles (within mechanical limits), dwell times, and multi-step velocity profiles; however, full validation of proprietary methods requires user-defined protocol documentation per ISO/IEC 17025 Clause 7.2.2.
Is calibration certification included with shipment?

Each unit ships with a factory calibration report traceable to NIST standards; optional UKAS-accredited calibration certificates are available upon request prior to delivery.
Can the AR-2000 operate on 110 VAC power supplies?

The standard configuration is 220 VAC (50/60 Hz); a 110 VAC variant is available as a configured option—specify voltage requirement at time of order.
What maintenance intervals are recommended for long-term accuracy?

Load cells should be verified annually using certified deadweight standards; encoder alignment and belt tension are inspected quarterly in high-utilization environments per the Maintenance Logbook (P/N MAINT-AR2000-REV3).
Is EZ-Date™ compatible with LIMS or MES integration?

Yes—via configurable ODBC drivers and flat-file export triggers; API-level integration requires site-specific development under ChemInstruments’ Partner Integration Program (PIP).
