A dome of silicone over the strip, made to follow a letter
Extruded silicone neon flex profile for channel letters and signage. The strip sits in a cavity inside the silicone and the rounded face spreads its light into a continuous line along straight runs, curves and return edges.
15 top-view sections, 6 × 11 to 100 × 30 mmPCB cavities 6–30 mm−40 °C to +200 °CCoils up to 100 m
What a top-view silicone neon flex profile is
This part is the silicone body of a neon flex. It is extruded as one profile with a cavity sized for the LED strip and a domed emitting face above it. The strip is fed into the cavity, the run is closed at the ends, and the light leaves through the dome rather than through a flat panel.
The sections in the range run from a 6 × 11 mm detail profile to a 100 × 30 mm body that carries two strips side by side. Between them there are square, rectangular and multi-colour variants, so a letter return, a sign edge and a facade line can use the same family of profiles. If the run has to be wrapped rather than built in, the silicone sleeve for LED strip does that job; if the light has to leave through a narrow side face, the side-emitting multicolour profile is the one to look at.
Two things are settled before anything is extruded: the section, which decides where the profile can be mounted and how much strip it takes, and the compound, which decides how the light reads along the run. We ask for the letter drawing and the strip data together, because one without the other cannot be quoted properly.
Three affiliated companies, one silicone chain
Extrusion is the last step of a chain we control from the compound up. The three companies below are affiliated; each does what it is set up for, and Yutian handles the profile you buy.

Why buyers place the profile with us
Compound in our own hands
Transmittance, colour and flexibility come from the compound. Because we compound and extrude, a change in the light effect is a formulation change, not a new supplier.
Extrusion from your drawing
We work from the section drawing or the groove you have to fill, and tell you whether an existing die fits or a new one is needed.
Finishing and accessories
Cut to length and packed to suit your line. Where the fixture needs a sealed end, the method is agreed before the order.
Paperwork that matches the claim
Certificates are described at the level they are held. Where a product-specific test report is needed, it is quoted as a separate project instead of implied.
Key advantages
A dome, not a flat window
The rounded face spreads the output of the strip across the width of the profile, so a run reads as a line of light instead of a row of diodes. How even it looks depends on the strip and its LED pitch, the depth of the cavity and the compound; we confirm it on a sample built around your strip.
Sections that match letter returns
From 6 × 11 mm upward. A narrow return on a small letter takes a small section, a deep sign edge takes a large one, and a long facade line can take the 100 × 30 mm body with two strips inside.
Silicone for heat and weather
The profile holds −40 °C to +200 °C, which covers a strip running warm inside the cavity and a facade in direct sun. Silicone also keeps its colour where clear plastics yellow.
Bends along the run
The profile follows a curve in the plane of the letter, so an outline is one piece instead of short straights joined at angles. The radius that is safe depends on the section, and we confirm it against the drawing before production.
Colour in the compound
Opal, translucent and tinted compounds are available, and the multi-colour variants put more than one tone in one profile. Colour is a formulation decision, so it is matched to a physical sample rather than to a screen.
No optical figure published
Transmittance and evenness depend on the strip you fit and the section you choose. We measure the light effect on the approved sample instead of quoting a catalogue percentage that would describe a different strip.
Sealed as an assembly
The profile itself is solid silicone. Where the fixture needs a rating, it is supplied as a sealed assembly rated IP67 or IP68, with the end treatment and sealing method agreed per project.
Converted before it ships
Coils up to 100 m or cut lengths, packed to suit the line. End caps and clips are quoted with the profile where the section uses them.
Top-view sections in the range
These are the top-view sections in the range. The cavity width is what decides which strip fits; the outside size is what decides where the profile can sit. Sizes are as stated in our section list.
| Section | W × H (mm) | Strip cavity | Typical use |
|---|---|---|---|
| 0611 | 6 × 11 | 8 mm | Hairline returns, small letters |
| 0613 | 6 × 13 | 10 mm | Slim letters and logo outlines |
| 0615 | 6 × 15 | 12 mm | Narrow signage edges |
| 1010 | 10 × 10 | 6 mm | Detail lines and small letter faces |
| 1212 | 12 × 12 | 8 mm | General letter and sign outlines |
| 1515 | 15 × 15 | 10 mm | Mid-size letters, display edges |
| 1616 | 16 × 16 | 10 mm | Standard channel letter face |
| 2014 | 20 × 14 | 12 mm | Wide letter faces and sign borders |
| 2015 | 20 × 15 | 12 mm | Wide letter faces |
| 2020 | 20 × 20 | 12 mm | Deep returns, larger letters |
| 3020 | 30 × 20 | 15 mm | Large letters and sign bodies |
| 7030 | 70 × 30 | 30 mm | Architectural lines, large sign faces |
| 10030 | 100 × 30 | 20 mm × 2 | Twin-strip bodies for long facade lines |
| 1616 four-colour | 16 × 16 | 8 mm | One profile, four colour zones |
| 2015 three-colour edged | 25 × 15 | 8 mm | Edged profile with three colour zones |
A section outside this list is a die project. Send the drawing and we will say whether an existing die can be adapted or a new one is needed, and quote it before anything is cut.
Top-view and side-view profiles compared
Both are silicone neon flex, and the choice usually comes down to how wide the lit line should be. Our own range covers both; the table is how we explain the difference to a buyer choosing between them.
| Top-view (this page) | Side-view | |
|---|---|---|
| Where the light leaves | Through a domed face along the length of the profile | Through a narrow side wall of the profile |
| How the run reads | A wide, soft line of light | A thin, bright line with a narrow field |
| Mounting | Sits on the letter face or in a routed channel | Sits against a surface or an edge, seen from one side |
| Best for | Channel letters, sign faces, larger outlines | Slim returns, edge lighting, tight architectural lines |

Applications
Where this profile earns its place:
Channel letters
Face and return profiles for illuminated letters.
Signage and lightboxes
Even edges on illuminated signs and boxes.
Architectural accents
Facade lines, canopies and entrance details.
Retail displays
Shelf edges, counters and display outlines.

OEM and private label
Profiles quoted to a drawing for a fixture maker.
Made to your specification
A profile is specified by five things. Send them together and the quotation comes back with a section that already fits them, or with the reason it does not.
- The section — a drawing, or the outside size and the strip cavity you need.
- The strip — PCB width, LED pitch and the light output per metre you are working to.
- The colour — opal, translucent or a tint, matched to a physical sample.
- The run — coil or cut lengths, and how the ends are closed.
- The quantity — metres per order and per shipment.
Where the drawing is still open, we propose a section from the range and confirm it with a sample before production.
Samples and lead time
Stock samples: free
Samples of standard stock items are sent free of charge, usually dispatched within 3 days.
Custom runs: quoted
A run in your compound, section or cut length is quoted with the project, including any die.
Production lead time
Standard items 5–7 days. Custom items 10–20 working days after sample approval.
Certificates and quality
The certificates below cover our compounds and our management system. They do not mean that every finished profile has been individually tested; a product-specific test report is a separate project and is quoted as one.
| Standard | What it covers | Level |
|---|---|---|
| ISO 9001:2015 | Quality management system | Company level |
| ROHS | Restricted substances | Raw-material level |
| REACH | Substance registration | Raw-material level |
| UL94 HB | Flammability of the compound | Raw-material level |
| Class 100,000 cleanroom | Production environment | In use |
Monthly inspection pass rate is 95% or higher and batch acceptance pass rate is 99%.
Frequently asked questions
Does the profile come with the LED strip inside?
We extrude the silicone body. Strip supply is a separate decision: many customers fit their own approved strip, and where a project needs a sealed assembly the strip, end treatment and testing are agreed as part of that project.
Which section fits my strip?
The cavity width decides it. Sections in the range take 6 mm to 30 mm PCB, and the 100 × 30 mm body takes two strips. Send the strip width and we will name the sections that fit it.
Will the line look even along a long run?
Evenness comes from the strip and its LED pitch, the depth of the cavity and the compound. We build a sample with your strip and confirm the effect; a profile alone does not fix the appearance of every strip.
Do you publish transmittance or uniformity values?
No. Those numbers are only meaningful for a particular strip, section and target effect. We measure the approved sample instead, so the reference belongs to your project.
How tight a radius can it bend?
It depends on the section. The profile bends in the plane of the letter, and every section has a radius beyond which the cavity distorts. Send the drawing and we will confirm what the section can do before production.
Is it suitable outdoors?
Silicone holds its colour and its flexibility outdoors far better than clear plastics. Where the fixture needs a water rating, it is supplied as a sealed assembly rated IP67 or IP68.
What temperature does it take?
−40 °C to +200 °C. If the strip runs the cavity hotter than that, tell us the conditions and we will say whether a compound change is needed.
What are the order terms?
Minimum order value USD 500. Stock samples are free; custom runs are quoted. Standard items ship in 5–7 days, custom items in 10–20 working days after sample approval.

Send the letter drawing and the strip you plan to fit
The drawing tells us the section and the radius; the strip tells us the cavity. With both we can name a section from the range, or say why a die is needed, and send a length to test.
