Typical XN-DZ200U Applications
Stretch-release tape is intended for applications that require both secure mounting and reworkable removal, including smart devices, lithium-ion battery pack assembly, and automotive display modules.
Lithium-ion Battery Pack & ESS Assembly
The Challenge:
In EV battery packs and energy storage systems (ESS), cells need to remain secured within the module structure. If the bonding method is difficult to remove, forced prying during rework or recycling may damage the aluminum-plastic pouch or metal casing, increasing service and safety risks.
The XN-DZ200U Solution:
XN-DZ200U has a holding power specification of ≥72 hours and an elongation at break specification of ≥800%. For rework or recycling, pull the reserved stretch end or a custom non-adhesive tab slowly along the bonded surface. As the tape stretches and thins, interfacial adhesion decreases, supporting low-residue separation of cells from trays or metal housings.
Battery Cell Assembly Configuration
Smartphone & Tablet Battery Mounting
The Challenge:
Portable electronics have limited internal space, so battery mounting must account for both bond reliability and service replacement. If disassembly relies on forceful prying with metal tools, the frame or lithium-polymer battery may be damaged. A controlled removal path should therefore be considered during structural design.
The XN-DZ200U Solution:
XN-DZ200U has a specified total thickness of 200 ± 10 μm and can be used in battery mounting designs that provide an accessible stretch end. Clean the substrate and apply even pressure during assembly. For rework, pull the tape slowly and parallel to the frame to reduce interfacial adhesion and the risk of damage during removal.
Consumer Electronics Integration
- ⚡ Peel Adhesion: 180° peel adhesion to stainless steel is specified at ≥2400 g/25 mm.
- ⚡ Thin Construction: The specified total thickness is 200 ± 10 μm for space-constrained assemblies.
- ⚡ Device-Level Validation: Drop, vibration, aging, and environmental compliance must be confirmed for the complete device and applicable product batch.
Automotive Display & Interior Trim Mounting
The Challenge:
Automotive HUD and center-display modules may be exposed to vibration, temperature cycling, and long-term aging while still requiring local service or module replacement. A difficult-to-remove adhesive system can damage the display module, plastic trim, or dashboard surface during disassembly.
The XN-DZ200U Solution:
XN-DZ200U can be considered for display-module mounting designs that provide stretch-release access. Pulling the tape steadily from the reserved stretch end during rework can help reduce secondary damage caused by prying. Automotive temperature, vibration, aging, and noise requirements must be validated against the actual module and test specification.
Automotive Project Validation Points
- 🚗 Temperature & Aging: Complete temperature cycling, high-temperature aging, and low-temperature testing to the target vehicle and module requirements.
- 🚗 Material Compatibility: Validate bonding and removal separately on the metal, PC, PP, and other surfaces used in the display module.
- 🚗 Low-Residue Separation: Confirm that the reserved stretch end, pull direction, and service clearance meet the intended repair procedure.
Substrate Compatibility Guide
Existing sample test data covers stainless steel, aluminum, PC, and PP. Other substrates and actual assembly conditions require separate sample validation.
| Substrate Material | Data Status | Test Data & Application Guidance |
|---|---|---|
| Stainless Steel / Aluminum Sheet | Sample Data Available | 180° peel adhesion is specified at ≥2400 g/25 mm. Sample results were 2949/2953 g/25 mm on stainless steel and 2833/2906 g/25 mm on aluminum sheet. Production use still requires validation on the actual surface. |
| Polycarbonate (PC) | Sample Data Available | 180° peel adhesion is specified at ≥2200 g/25 mm, with sample results of 2682/2675 g/25 mm. Resin grade, texture, and surface treatment can affect performance. |
| Polypropylene (PP) | Sample Data Available | 180° peel adhesion is specified at ≥2200 g/25 mm, with sample results of 2666/2703 g/25 mm. This low-surface-energy material still requires confirmation using the actual grade and cleaning method. |
| ABS / PE / Glass | Testing Required | The current XN-DZ200U technical data does not include test values for these substrates. Validate the actual material grade, cleaning method, application pressure, and dwell time. |
| Painted & Coated Surfaces | Testing Required | Confirm the coating's adhesion to its substrate, then verify whether stretch removal causes delamination, discoloration, or surface damage. |
| Silicone Rubber & Fluorinated Release Surfaces | Test Required | These low-surface-energy or release-treated surfaces are generally difficult to bond. Conduct a small-scale test before deciding whether surface treatment or a different adhesive system is required. |
| Porous Substrates (Wood / Paper) | Not Recommended | Stretch release requires sufficient cohesive strength in the substrate. Loose porous surfaces may tear or delaminate during removal, so the risk of material damage should be assessed first. |
