PW Universal High-Temperature Holding Power Tester PW-HP60T2-90S

Overview

The PW Universal High-Temperature Holding Power Tester PW-HP60T2-90S is an engineered solution for quantifying the static shear resistance of pressure-sensitive adhesives (PSAs), protective films, double-sided tapes, and laminating adhesives under controlled thermal stress. Operating on the principle of constant-load vertical peel testing at a fixed 90° orientation, the system subjects specimens to sustained gravitational loading while maintaining precise temperature uniformity across all 60 independent test stations. Unlike dynamic tensile testers, this instrument evaluates time-dependent adhesive failure mechanisms—such as creep deformation, interfacial delamination, and cohesive splitting—under isothermal conditions up to 200°C. Its design adheres to core ASTM D3654/D3654M (Standard Test Method for Shear Adhesion of Pressure-Sensitive Tapes) and ISO 4587 (Adhesives — Determination of peel and shear strength of bonded assemblies) frameworks, enabling traceable, reproducible data generation for R&D labs, QC departments, and regulatory submissions.

Key Features

• 60 fully independent test stations distributed across four thermally isolated layers—each with dedicated 90° vertical load alignment and individual digital timer control (0–99999 minutes)
• Precision temperature regulation from ambient +5°C to 200°C, maintained within ±1.5°C across all test zones via PID-controlled forced-air convection and insulated chamber architecture
• Modular weight system: standard 1 kg stainless-steel masses supplied; optional calibrated weights (100 g, 500 g, 2 kg) available for graded shear load profiling
• Structural integrity ensured by 1.5 mm thick support plates and 1.0 mm reinforced shelf plates, fabricated from cold-rolled steel with dual-surface treatment (anodized base + electrostatic epoxy powder coating)
• Integrated mechanical damping: progressive coil springs combined with elastomeric bushings absorb vibration during mass loading/unloading; perimeter guardrails prevent accidental weight displacement
• Human-centric ergonomics: front-access specimen loading, tool-free plate adjustment, and standardized 150 × 50 × 1.5 mm specimen mounting footprint compatible with ISO 2922-compliant test substrates

Sample Compatibility & Compliance

The PW-HP60T2-90S accommodates rigid and flexible substrates—including aluminum, stainless steel, PET, PC, and acrylic panels—within defined dimensional limits (150 × 50 × 1.5 mm). It supports both single- and double-coated PSA configurations, as well as transfer tapes and hot-melt film adhesives. All thermal and mechanical operations comply with ISO/IEC 17025 calibration traceability requirements when used with NIST-traceable weights and certified thermocouples. The system’s operational envelope aligns with ASTM D1000 (Pressure-Sensitive Tape), PSTC-107 (Holding Power), and JIS Z 0237 (Adhesive Tapes) test protocols. For pharmaceutical or medical device applications, the unit supports GLP documentation workflows through external data logging interfaces.

Software & Data Management

While the PW-HP60T2-90S operates as a standalone hardware platform with local LED timers and manual pass/fail assessment, it integrates seamlessly with third-party laboratory information management systems (LIMS) via RS-232 or optional USB-to-serial adapters. Raw test logs—including start time, duration, temperature setpoint, station ID, and observed failure mode (e.g., “complete detachment”, “slippage >5 mm”, “cohesive fracture”)—can be exported in CSV format for statistical process control (SPC) analysis. When paired with PW’s optional DataBridge module, the system provides audit-trail-enabled timestamping compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures.

Applications

• Quality assurance of automotive interior bonding tapes exposed to cabin temperatures exceeding 90°C
• Formulation screening of high-temperature acrylic PSAs for EV battery module lamination
• Accelerated aging validation of optical clear adhesives (OCA) used in display assembly
• Comparative evaluation of silicone vs. rubber-based PSA performance degradation above 120°C
• Regulatory submission support for Class I/II medical device adhesives requiring ISO 10993-5 cytotoxicity correlation studies
• Supplier qualification testing per OEM-specific material specifications (e.g., Ford WSS-M99P1111-A, GMW15635)

FAQ

What is the maximum allowable test duration per station?
Each station supports continuous timing up to 99,999 minutes (~69.4 days), suitable for long-term creep and aging studies.
Can the system operate at temperatures below ambient?
No—the minimum operating temperature is ambient +5°C; sub-ambient capability requires external environmental chamber integration.
Is calibration certification included with shipment?
A factory calibration report covering temperature uniformity and timer accuracy is provided; ISO/IEC 17025-accredited calibration is available as an optional service.
How is temperature uniformity verified across all 60 stations?
During commissioning, a 9-point thermal mapping protocol (per ASTM E220) is performed using six calibrated PT100 sensors distributed across upper/middle/lower layers.
Does the system meet CE or UL safety standards?
The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment; CE marking is applied upon regional conformity assessment by authorized EU Notified Body.
