Double Sided Ixpe Foam Tape
OPALUS PACK is a manufacturer of double sided ixpe foam tape designed for industrial assembly applications requiring stable compression performance, dimensional accuracy, and reliable bonding strength. The tape is based on irradiation cross-linked polyethylene foam with a closed-cell structure that improves long-term stability under mechanical load. Compared with conventional PE or EVA foam tapes, IXPE provides better thickness retention, lower compression set, and more predictable behavior in vibration and thermal cycling environments commonly found in automotive, electronics, and battery module assemblies.

Product Overview
This double sided ixpe foam tape is manufactured using a controlled irradiation cross-linking process that creates a uniform closed-cell foam structure. The result is improved mechanical stability compared to conventional non-crosslinked PE foam materials. In real production conditions, this structure helps maintain more consistent thickness during converting processes such as slitting and lamination. OPALUS PACK focuses on maintaining production stability across rolls, ensuring that density and thickness variations remain within controlled industrial tolerances. This is especially important for automated die-cut applications where even small variations can affect assembly accuracy. Compared with EVA foam systems, IXPE demonstrates better resistance to long-term compression deformation, making it more suitable for structural spacing and cushioning functions in precision assemblies.
Benefits
- Maintains stable thickness under continuous compression conditions
- Improves long-term structural reliability compared to EVA foam
- Reduces misalignment risks in multi-layer assemblies
- Provides consistent die-cut performance in high-speed production
- Supports vibration and thermal stability in industrial environments
- Enhances repeatability in automated assembly systems
How does IXPE foam improve die-cut precision and assembly repeatability?
The cross-linked IXPE foam structure provides uniform internal cell distribution, which reduces edge tearing and deformation during die-cut processing. This allows OPALUS PACK to maintain consistent gasket geometry even in complex shapes used in electronics and automotive applications. The improved structural integrity also ensures that foam parts return to their designed thickness after compression, which is critical in automated assembly systems where stack height and positioning accuracy directly affect final product performance.

- Assembly interface material in electronic housings where alignment needs to stay stable
Why does thickness stability matter in long-term compressed applications?
In real industrial environments, foam materials are often subjected to continuous compression, vibration, and thermal cycling. IXPE foam resists permanent deformation due to its closed-cell cross-linked structure, which distributes stress more evenly across the material. This reduces compression set over time and ensures that the bonding interface maintains consistent spacing. In applications such as EV battery packs and automotive interiors, this stability directly reduces mechanical fatigue and prevents misalignment caused by long-term material creep.
