Injection Moulded LED Neon Flex — IP67/IP68 | DENO

Outdoor & façade exposure

Specify for permanent exterior installation above the waterline (IP67).

The silicone is injection moulded onto the FPCB in one shot, so there is no glued cover to open up after a winter of thermal cycling — the failure mode PVC neon rope light shows in its second outdoor summer. UV-stabilised silicone keeps its colour instead of yellowing, and the body stays elastic from −30 °C to +80 °C, so a façade run installed in summer will not go brittle in a January frost. Feed with low-voltage DC and plan short runs per feed to hold end-of-run brightness across a long elevation.

• Sealed silicone body
• UV-stable silicone, −30 °C to +80 °C
• Low thermal load

Pools, spas & wet areas

Suitable for pool surrounds, spa ceilings and steam-adjacent joinery — not for submersion.

IP67 covers rain, splash, wash-down and steam — pool decks, shower reveals, sauna ceilings and spa coves — but the body is not intended to sit under water. Mount it above the waterline in an aluminium groove so condensate drains away from the feed joint, run low-voltage DC for wet-zone safety, and choose the IP68 variant where the channel can flood.

Architectural contour & signage

Bends along its moulded axis at standard radii — the right pick for façade outlines, cove lighting and long architectural runs.

Injection moulded LED neon flex takes its curve along its moulded axis, which is what decides whether a shape is possible without cutting and re-soldering. At standard radii the outside of the curve stays evenly lit: the LED pitch is matched to the diffuser depth so you read a continuous line of light rather than dots, even at 30 cm. Printed cut marks with indexed solder pads underneath let a sign maker shorten a letter stroke on site and re-seal it, and mounting clips, aluminium grooves and moulded bend grooves cover surface, recessed and free-form fixing.

What is an injection moulded LED neon strip?

An injection moulded (US: molded) LED neon strip is formed by hot-melting silicone directly around the FPCB in a single shot, instead of sliding the board into a pre-extruded tube. There is no air gap and no glue seam, so water has no path in and the diffuser sits at a fixed distance from every LED — which is what keeps the light line even over a 20 m façade run.

Why is a seamless injection neon strip more reliable than an extruded tube?

Extruded neon relies on adhesive to bond the cover, the tube and the end cap; UV and thermal cycling eventually open that bond and the run fogs from the inside. A seamless injection moulded LED neon strip has one continuous silicone body, so that adhesive bond line does not exist — the failure path is removed by construction rather than compensated for. DENO does not publish an accelerated-ageing figure for this body style; ask for the current IP and material data on the specific model you are quoting.

Which IP rating does injection moulded neon flex carry, and can it go underwater?

The rating is model-specific, not a family-wide claim. The catalogue injection-moulded body listed in this series (20×18 mm, 24V) is specified IP67 — rain, splash and temporary immersion — which covers façade, cove and signage work. IP68 continuous-immersion builds are made to order and must be confirmed in writing for the project. For any submerged detail DENO specifies a sealed cable gland and a junction box outside the water line, and the rating on the written product specification is the one that applies.

Can injection moulded neon flex handle outdoor façade temperature swings?

Silicone stays flexible over a far wider band than PVC and expands at a rate close to the FPCB, so the body does not shear at winter temperatures the way a PVC jacket does. The rated operating window is still model-specific — the catalogue 20×18 mm build is specified −20 °C to +50 °C — so take the figure from the written specification of the model you are quoting. Outdoor façade builds use UV-stabilised silicone and a heavier-copper FPCB that spreads heat instead of concentrating it under each LED.

Do injection moulded end caps really stop water ingress?

The termination is the deciding detail. Most field failures on waterproof neon flex start at a glued cap that shrank away from the body. An injection-moulded end cap is fused to the same silicone compound, so cap and body behave as one part under thermal cycling instead of as two bonded parts. DENO inspects terminations before despatch; the protection rating that applies to an order is the one written on that model's specification.

Can the injection moulded body be made in a custom colour or profile?

Yes — body colour (milky white, black, grey, colour-matched), cross-section, wall thickness, light-emitting window width and printed cut interval are all tooling parameters, not catalogue limits. Because DENO owns the moulding line, a project-specific integrated-moulding neon strip is set up from an existing stack-up rather than quoted as a new product programme.
