Yuelian YL-S90 FINAT FTM1 180° Peel Adhesion Tester

Overview

The Yuelian YL-S90 FINAT FTM1 180° Peel Adhesion Tester is a precision-engineered electronic tensile testing system designed specifically for standardized quantitative evaluation of pressure-sensitive adhesive (PSA) performance in accordance with FINAT Technical Method No. 1. It operates on the principle of controlled-angle mechanical separation—applying a constant-rate unidirectional force to peel a PSA-coated specimen from a standardized substrate at precisely 180°, enabling direct measurement of interfacial adhesion energy under defined environmental and kinematic conditions. The instrument implements the full FINAT FTM1 protocol—including mandatory 20-minute and 24-hour dwell times, specified glass test plates, FINAT-certified roller application, and strict environmental conditioning (23 ± 2 °C, 50 ± 5 %RH). Its high-resolution load cell (1/500,000 full scale), sub-micron displacement resolution, and programmable speed control (0.1–500 mm/min, default 300 mm/min per FINAT) ensure traceable, repeatable, and auditable data acquisition suitable for QC laboratories, R&D validation, and regulatory submission.

Key Features

• Compliance-ready architecture: Pre-configured test profiles for FINAT FTM1, ASTM D3330, GB/T 2792, and other major peel adhesion standards.
• High-fidelity force measurement: Dual-range load cell with ±0.30% full-scale accuracy and 1/500,000 internal resolution—validated per ISO 7500-1 Class 0.5 requirements.
• Precision motion control: Stepper motor-driven ball-screw actuation system delivering >85% mechanical transmission efficiency and stable velocity regulation across the full speed range (0.1–500 mm/min).
• Modular fixture interface: Quick-release coupling system compatible with standard 180° peel jaws, FINAT roller applicators, and auxiliary fixtures for tensile, compression, tear, shear, and loop tack testing.
• Dual-mode operation: Standalone touchscreen interface (B-type display) with real-time force–displacement curve visualization; seamless USB/RS-232 connectivity for PC-based analysis via proprietary software.
• Automated test sequencing: Programmable dwell timers, auto-return post-test, overload protection, upper/lower limit stop, and failure-triggered halt—supporting GLP-compliant workflow execution.

Sample Compatibility & Compliance

The YL-S90 accommodates specimens conforming to FINAT FTM1 specifications: 25 mm wide strips, ≥175 mm length, cleanly cut with orthogonal edges. Standard substrates include optically flat soda-lime glass plates (cleaned per FINAT solvent protocol using MEK, acetone, or diacetone alcohol), though stainless steel, aluminum, or polyester film substrates may be substituted with explicit annotation in reporting. All test plates must undergo ≥4-hour equilibration under standard laboratory conditions (23 ± 2 °C / 50 ± 5 %RH) prior to use. The system supports classification and documentation of failure modes per FINAT nomenclature: CP (clean plate), PS (plate staining), CF (cohesive failure), AT (adhesive transfer), and PT (substrate tearing). Full compliance with Chinese national standards (GB/T 2792, GB/T 12914, GB/T 1040) and international norms ensures data acceptability in cross-border supply chain audits and FDA-registered facility validations.

Software & Data Management

The included Windows-compatible software provides full test method definition, parameter logging, real-time graphing, and statistical post-processing (mean, SD, CV%, min/max). Raw force–displacement datasets are exported in CSV or XLSX format for integration into LIMS or enterprise QA systems. Audit trail functionality records operator ID, timestamp, calibration status, and parameter changes—meeting foundational requirements for 21 CFR Part 11 alignment when deployed with user authentication and electronic signature modules. Data export includes automatic annotation of dwell time, substrate type, failure mode, and environmental monitoring logs where integrated sensors are present. Calibration certificates follow ISO/IEC 17025 traceability pathways through CNAS-accredited providers.

Applications

This instrument serves as a primary metrology platform for adhesive formulation development, incoming raw material qualification, in-process release testing, and shelf-life stability studies. Typical use cases include: evaluating acrylic, rubber, silicone, and hot-melt PSA formulations on labelstocks, medical tapes, protective films, and die-cut components; validating liner release characteristics; benchmarking competitive products against internal specifications; supporting root-cause analysis of delamination failures in packaging or electronics assembly; and generating technical dossiers for ISO 9001, IATF 16949, or MDR-compliant technical files. Its broad force range (10 N–1 kN) and modular design also support non-adhesive applications—tensile strength of thin films, puncture resistance of nonwovens, tear propagation in elastomers, and compressive yield of foams—making it a versatile physical property characterization tool.

FAQ

What is the required dwell time for permanent peel testing per FINAT FTM1?
Per FINAT FTM1, permanent peel force is measured after 24 hours of contact between the PSA and the test plate under standard conditions (23 ± 2 °C / 50 ± 5 %RH).
Can the YL-S90 perform tests at speeds other than 300 mm/min?
Yes—the instrument supports fully programmable speed from 0.1 to 500 mm/min via PC software or front-panel input, allowing method adaptation for non-standard protocols or troubleshooting.
Is the glass test plate cleaning procedure validated per FINAT guidelines?
Yes—the recommended solvent sequence (MEK or acetone final rinse), lint-free medical gauze wiping protocol, and triple-cleaning requirement align precisely with FINAT FTM1 Annex A.
Does the system support automatic calculation of N/25mm units?
Yes—software applies automatic width normalization and reports results directly in N/25mm, consistent with FINAT, ASTM, and GB reporting conventions.
How is traceability maintained for calibration and maintenance?
Calibration certificates include equipment ID, date, technician signature, uncertainty budget, and reference standard traceability to NIM (China National Institute of Metrology); maintenance logs are stored within the software audit trail.
