Cross Linked Polyethylene Foam Tape

Both Side Tape Company is a manufacturer of Cross Linked Polyethylene Foam Tape made with a stable cross-linked PE foam carrier instead of a film-only base. This IXPE foam tape is designed for parts that need controlled compression recovery, clean die-cut edges, and reliable adhesive lamination. With typical thickness from 0.5 mm to 10 mm and density from 25-100 kg/m3, it supports sealing, spacing, cushioning, and gasket applications where shape retention matters after cutting and assembly pressure.

Product Overview

Cross Linked Polyethylene Foam Tape is not the same as ordinary polyethylene film double sided tape. The working layer is an IXPE foam body, giving the tape a softer, thicker, and more resilient carrier for parts that must absorb pressure or fill small gaps. During slitting, rewinding, lamination, and die cutting, the cross-linked PE foam carrier helps the material keep a more stable shape, so narrow strips and small gasket pieces are less likely to stretch, collapse, or move away from the drawing size.

The fine closed-cell structure gives the foam a smoother surface for adhesive lamination and a more even compression response during use. Density should be selected according to the part design, not only by touch.

Adhesive performance also depends on the foam surface and lamination control. After coating or laminating, the sample should be checked after storage under roll tension, because edge curl, adhesive lift, liner release, or foam thickness loss may not appear during the first peel test.

Benefits

Fine closed-cell foam tape structure helps reduce moisture absorption and supports a steadier sealing contact line.
Controlled compression recovery, typically >=90 percent after short-term compression, helps gasket and spacer parts regain working thickness.
Cross-linked PE foam carrier improves dimensional stability after slitting, rewinding, adhesive lamination, and die cutting.
Stable density improves die-cut edge cleanliness and reduces rough tearing on narrow-width strips.
Proper liner support helps reduce adhesive squeeze-out, edge curl, and liner tearing during conversion.
The foam body provides cushioning and vibration damping without making the tape feel loose or unstable.

What should be checked during 24-72h sample observation after adhesive lamination?

Initial tack is only one part of the test. For adhesive laminated foam tape, a 24-72h sample observation gives a clearer view of whether the foam, adhesive, and liner are working together. The sample should be checked for edge curl, adhesive lift, foam collapse, liner release, and width change after rewinding or die cutting.

For narrow strips, gasket pads, and spacer parts, a stable sample should keep dimensional change within a typical <=1.0 percent range under standard observation conditions. The adhesive layer should show even wet-out on the foam surface without obvious delamination. This check is especially useful before mass production, because roll tension can reveal hidden lamination problems that a quick hand test may miss.

Product Production

Applications

Die-cut foam gasket tape for industrial panels, control boxes, and equipment housings.
Spacer pads for display frames, nameplates, electrical insulation parts, and appliance assemblies.
Closed-cell foam tape for HVAC duct gaskets, dust-blocking contact surfaces, and moisture-resistant sealing.
Cushioning pads for electronic components where clean edges and controlled recovery are required.
Narrow-width laminated strips for panel bonding, gap filling, and vibration damping.
Soft sealing parts where the foam needs to compress during assembly and recover after pressure is released.

How does fine closed-cell IXPE foam improve die-cut edge quality and dimensional stability?

Fine closed-cell IXPE foam gives the carrier more internal support during cutting. The edge is less likely to crumble, stretch, or leave loose particles, which matters for thin gaskets, small pads, holes, and narrow strips. When foam density, blade clearance, and liner support are matched correctly, the tape keeps better edge definition and reduces adhesive squeeze-out around the cut line.

This also improves placement accuracy during assembly. For display frame pads, spacer strips, electronic cushioning parts, and sealing gaskets, even small edge deformation can affect fit. The cross-linked foam body helps the part recover after cutting and compression, improving thickness retention and dimensional stability during use.

FAQ

Q1: What is Cross Linked Polyethylene Foam Tape used for?

It is used for sealing, spacing, cushioning, gasket, and die-cut mounting parts that need stable foam recovery and clean edges.

Q2: How should density be selected?

Lower density supports soft cushioning, while higher density improves edge support, spacer stability, and compression resistance.

Q3: Why is 24-72h sample observation useful?

It helps check edge curl, adhesive lift, foam collapse, liner release, and dimensional change before mass production.

Q4: Is this tape the same as polyethylene film double sided tape?

No. This product uses an IXPE foam carrier, so it provides thickness, cushioning, compression recovery, and closed-cell sealing support.
