Custom inserts for applications that value appearance, flexibility and permanent ESD performance

Black ESD IXPE foam roll

ESD IXPE combines flexibility, a smooth surface and permanent ESD performance. It is suitable for electronic-product trays, dividers and inserts with higher appearance and finish requirements. The raw-material form is not the final selection criterion; customers should compare finished, fabricated solutions.

Core Point 1: The Original Surface Has an Integral Skin

The original IXPE material has a relatively smooth integral surface skin, one of its main visual differences from EVA. This skin works well on areas that require a clean presentation surface. However, longitudinal cuts, die-cut edges and CNC-machined cavities expose the internal cells and cannot be guaranteed to retain the skin.

Requiring every cut face and internal cavity to retain a skin increases structural and fabrication complexity. The design should identify where the skin is functionally or visually necessary instead of requiring every surface to look identical.

Core Point 2: Thick Structures Require Multi-Layer Thermal Lamination

The standard single-layer thickness is 5±0.3 mm. Finished thicknesses above 5 mm are produced by thermal lamination of multiple layers. Layer count affects appearance, accumulated tolerance, processing steps and cost, so it should be determined by cavity depth and product-support requirements rather than increased without analysis.

Core Point 3: Multiple Fabrication Methods Are Available

IXPE can be fabricated by die cutting, bonding, CNC machining and thermal lamination. The process depends on the drawing and order quantity: CNC may be evaluated for complex or low-volume designs, while die cutting may suit stable production designs. The Yufa team confirms the final process for each project.

Core Point 4: Permanent ESD Performance

IXPE derives its ESD performance from the material itself rather than a surface coating. Surface resistance is 1.0×10⁵–1.0×10⁹ Ω and static decay is under 2.0 seconds. Normal wiping and handling wear do not remove the ESD function.

Key Technical Data

Which Projects Should Consider IXPE First?

• The finished front surface and appearance are important

• A flexible, closed-cell electronics insert is required

• Permanent ESD performance and repeated use are required

• Cut faces and internal cavities do not need to retain the surface skin
