What Information Should I Send for a Silicone Sheet Quotation?
A practical checklist of the size, thickness, hardness, quantity and application details needed for a silicone sheet quotation, plus what to send for custom-cut parts.
If you want a fast, accurate quotation for silicone sheet, send a short set of details: product or material type, size (sheet size or roll width), thickness, hardness if known, quantity, and how the sheet will be used. Add surface, colour, or drawing information if the finish matters or the sheet will be cut into parts. That is enough to start a real conversation — you do not need a complete technical packet before your first inquiry.
Most quotations that stall do not stall because the buyer sent too little. They stall because a few key details are missing, and the supplier has to ask back and forth. Below is what each piece of information actually changes on our side, and how to describe it if you are not sure of the exact term.
The Basic Information Needed for a Silicone Sheet Quote
Here is the short version first, then the reasoning behind each item.
- Product or material: silicone sheet, or something further processed
- Size: sheet dimensions or roll width
- Thickness: even an approximate figure helps
- Hardness: in Shore A, if you already know it
- Quantity: evaluation, first order, or ongoing demand
- Application: what the sheet touches and what it must survive
- Surface or colour: if it matters for your product
- Drawing or sample: only if the sheet is being cut or fabricated
Every item on that list changes something concrete — which material we look at, how the sheet is produced or cut, and how the quantity is quoted. When one or two items are missing, the supplier has to guess or ask, and that is what turns a quick quotation into a slow email thread. The sections below take the list apart, in order.
1. Size and Dimensions
Size is the first thing that affects both material usage and processing, so describe it the way you actually need the sheet delivered.
If you need the sheet as supplied, give the sheet size — for example, 1200 × 2000 mm. If it comes in roll form, tell us the roll width your equipment can handle, and the length or roll format you prefer. If the sheet will be cut into parts, give the finished (cut) part dimensions instead of the sheet size you think we might use. We can usually work backward from a finished part to the right sheet format, but we cannot turn an approximate sheet size into a part that has to fit something.
A common source of confusion in sheet inquiries is that the buyer sends a sheet size, while the real requirement is a cut part with specific outer dimensions. Those are two different quotations. If you are in that situation, the section on drawings below applies to you.
2. Thickness
Thickness drives material cost, weight, and how the sheet behaves in use, so it belongs in the first message if you know it. If you are not sure, do not guess, and do not treat it as a reason to postpone your inquiry. Tell us the current situation instead: you are replacing an existing sheet, you have a sample in hand, or you know the conditions the sheet will work under. From there, we can narrow the range together.
What you should avoid is copying a thickness from a similar product without checking whether the same figure fits your application. A thickness that works in one situation can be wrong in another, and it is easier to confirm this before quoting than after a batch has been produced.
3. Shore Hardness
For most silicone sheet inquiries, hardness is usually given in Shore A. If you know the number, send it. If you do not, your inquiry is still valid; many buyers start without it.
In that case, send the application and what the sheet needs to do: how much it should compress under load, whether it needs to stay flexible, whether it is sealing against a surface, or whether it mainly acts as a protective layer. If you have an existing sample, even a worn one, tell us — an existing sample can be more useful than a written description when the hardness is unknown. Confirm the final hardness with the supplier rather than picking a number from a similar product, because hardness affects how the sheet seals, cushions, and recovers.
4. Quantity
Quantity tells us which production route makes sense. There is a practical difference between a few sheets for evaluation, a trial order before a larger commitment, and recurring monthly or annual demand.
You do not need to commit to a final volume to send an inquiry. It is more useful to give a realistic picture: how much you need first, and how much you expect over time if the material performs well. If you genuinely do not know the future volume yet, say that. If you know both the trial quantity and the expected repeat demand, list them separately. Exact order minimums and quantity policies should be confirmed directly with the supplier, as they depend on the material, the size, and how the sheet is processed.
5. Application and Working Environment
This is one detail buyers often leave out, and it can change the recommendation.
"1200 × 2000 mm, 2 mm, 50 sheets" describes what to produce. It does not describe what the sheet must survive. Two sheets with identical dimensions can point to different material or processing choices depending on whether they will be:
- repeatedly stretched and released, such as a membrane
- compressed in a sealing joint
- used as a cushioning or protective layer
- formed over a shape, as in vacuum forming
- in contact with food equipment surfaces
- exposed to heat during normal operation
- in contact with oils, cleaning agents, or other chemicals
If your application is not on that list, describe it in your own words. Telling the supplier the final use is more valuable than sending additional dimensions, because the use determines which material properties actually matter. If the application needs more information, we would rather ask before recommending a material.
Do I Need a Drawing for a Silicone Sheet Quotation?
For a plain sheet or roll, generally no. Size, thickness, hardness, quantity, and application are usually enough to start a quotation.
A drawing or sample becomes important when the silicone sheet is not the final product — when it will be cut or fabricated into parts such as gaskets, pads, rings, or shaped pieces with holes or slots. In those cases, a drawing, a sketch with key dimensions, or a physical sample reduces back-and-forth before quoting or production. It does not need to be a professional CAD file; a clean sketch with the important dimensions marked is often enough to start.
If you have a drawing or sample, mention it in your inquiry and we will confirm the best way to review it — we will tell you what to send and how. The same applies to custom rubber parts and gaskets made from drawings or samples.
What If I Don't Know All the Specifications Yet?
Then send what you do know, and say clearly what you don't. That is a normal starting point, not a problem.
At minimum, include:
- what the sheet or part will be used for
- approximate size
- approximate thickness, if you have any idea
- quantity you are considering
- whether a current sample or drawing exists
From there, the supplier can ask a few focused questions and usually close the gaps quickly. An inquiry with an honest "not confirmed yet" on hardness is far more useful than one with invented numbers that have to be corrected later.
A Simple Silicone Sheet RFQ Example
Here is a format you can copy and adapt. It is an example of how to write an inquiry — not a recommended specification.
You can send this almost as-is through the contact form, replacing the details with yours. If some lines say "not confirmed" or "not sure yet," leave them in — that tells the supplier where to focus.
Before You Send the Inquiry
A quick check before you hit send:
- Product or material
- Size (sheet size, roll width, or finished part dimensions)
- Thickness
- Hardness (or "not confirmed yet" — that is acceptable)
- Quantity
- Application / working environment
- Drawing or sample (if the sheet will be cut or fabricated)
If you have all seven, or you have honestly marked what is missing, you are ready. Get a Quote and we'll review the details and let you know what still needs to be confirmed.
