LKJ® Foam Tape

What is double-sided foam tape used for?

Double-sided foam tape is used wherever two parts have to be joined without visible screws, rivets or wet adhesive, and where at least one of the surfaces is uneven. A flat film tape needs both faces to meet cleanly. A foam carrier does not: it compresses where the gap is tight and stays proud where the gap is wide, so the adhesive keeps contact right across the joint.

On LKJ® Foam Tape the carrier is 2mm EVA foam coated on both sides, so it works as a fastener and as a cushion at the same time. That is why it turns up in battery assemblies, where it gives stable adhesion when fixing components, and in electronics and signage, where it secures circuit boards, battery cells, displays and name plates. It also takes the place of mechanical fixings on cable mounts, wall mounts and automotive interior trim.

Foam tape is one of six families in the LKJ® specialty tapes range, each chosen by the job it has to do rather than by general purpose.

For thinner joints where a foam gap line would show, chrome posters, mono cartons, dome labels, a tissue carrier is the better fit. The group makes those under the PTK® brand, and you can compare grades on the Prateek® Tapes double-sided tissue tape range before deciding which carrier your job needs.

Will EVA foam tape stick to metal, plastic and painted surfaces?

Yes. LKJ® Foam Tape is double-stick and heat insulating, and it is specified for use on metal, plastic and painted surfaces. In practice the deciding factor is preparation rather than the substrate itself: the surface has to be dry, free of dust, oil and release agents, and at room temperature when the tape is applied.

The tape is also ultra-flexible, so it conforms to curved and irregular substrates instead of lifting at the ends the way a stiff backing does. That matters on trim pieces, mouldings and enclosure lids, which are rarely flat.

Because bonding needs vary so widely, the tape is made in several grades for light, medium and heavy bonding. If you are unsure which grade suits your part, send the substrate details and the expected load and we will tell you which grade to trial.

What thickness and widths does LKJ® Foam Tape come in?

The standard construction is a 2mm EVA foam carrier with adhesive on both sides and a paper release liner printed with the LKJ® logo. Rolls are slit from 4mm up to 1020mm, which covers everything from narrow strips for cable clips to wide sheets for panel and display mounting.

Custom sizes, densities and adhesive systems are available on request, so the tape can be matched to a specific die-cut shape or to a particular assembly line. Jumbo rolls of 2mm double-sided EVA foam are part of the group range as well.

Lalit Jain Industries has been making industrial adhesive tapes since 1987 and is ISO 9001:2015 certified. The full group catalogue, including the foam, acrylic foam and EV-industry ranges, is listed at Lalit Jain Industries Pvt. Ltd. if you need a product this site does not carry.

What are LKJ® HBA acrylic foam tapes used for?

LKJ® HBA (High Bond Adhesive) acrylic foam tapes are a separate construction from the EVA foam grades above, and they do a structural job. They are used in structure glazing, aluminium composite panels, windows and door bonding and in many other places, and they are specified to replace rivets, bolts, welds and other mechanical fixings.

That is the point of a high bond adhesive foam. A rivet or a weld carries the load at a handful of points and leaves a mark at each one; an HBA tape spreads the load along the whole length of the joint, so a panel can be bonded without drilling the facade and without a visible fixing. Removing those operations from the assembly also increases productivity on the line. The tapes are described as environment proof.

HBA is also available in a transparent colour, which is a perfect solution for glass-to-glass bonding: the joint carries the load without a dark line showing through the glass. Various thicknesses are available, from 0.4 mm up to 3 mm, so the tape can be matched to the gap the joint actually has. Highly specialised foam tapes from 3M are available alongside the LKJ® range.

Send the panel size, the substrates and the gap you are bonding across and we will confirm which HBA thickness to trial. Before you commit a detail, our guide on HBA acrylic foam tape versus rivets, bolts and welds sets out the engineering case on both sides, including where a mechanical fixing is still the right answer.

What is single-sided foam tape used for?

Single-sided foam tape has adhesive on one face only, so the foam itself is the working surface rather than a carrier between two parts. A wide range is available in various thicknesses, on EVA and PE base, with hot-melt, solvent and acrylic based adhesive: the adhesive is chosen for the substrate and the service temperature rather than assumed.

The jobs it does are insulation, reducing vibration and blocking noise. In practice that means the foam is stuck down and then either seals against another surface or simply damps what is behind it. Listed uses are HVAC equipment panels, service as a fibre-free insulation alternative, metal-to-metal seals, gaskets and gap filler, and wrapping chilled water lines.

Single-sided foam tapes are also widely used for fixation of aluminium doors, panels and windows, which is the same family of work the HBA acrylic foam grades cover at the structural end. If the joint has to carry a panel, ask about HBA; if it has to seal, damp or insulate, single-sided foam is the simpler construction to specify. For how the foam base and the adhesive system each change that choice, read EVA versus PE foam tape, and which adhesive to use.
