Design Notes

A transparent silicone sheet with a smooth finish on both sides. A powdery residue builds up on the laser cut edge but this is easily wiped off.

This silicone maintains it's properties over a temperature range of –65° to +400° F.

Durometer hardness is 40A (medium soft). Durometer tolerance is ±5.

Tensile Strength: 800 psi

Unlike most other materials silicone will be shipped without the surrounding material sheet. The sticky paper we normally use to hold all cut pieces within the surrounding material does not stick to silicone so we opt to individually pull designs off the laser and bag them for shipping. Add a cutting line around all pieces of the silicone that you want to have shipped.

Engraving Silicone

Line engraving is recommended over area engraving. Area engraving will leave a white powdery residue on the material.

There are 3 types of engraving possible with laser cutting. Area engraving, line engraving and a combination of both.

Area engraving is great it you need to mark a large area on the surface of the material. To specify area engraving set your shapes to have a fill color of black with RGB values of 0, 0, 0. The way this engraving is performed is like an old dot matrix printer except instead of dots of ink it uses pulses of the laser beam. This is a surface finish not deep enough to be used for pocketing or inlays. The depth of the engraving ranges between 0.1-0.2mm.

Line engraving is like a really shallow cut. To achieve this effect the stroke color to red with RGB values of 255, 0, 0 and set the stroke style to a width of 0.01 mm. The laser beam follows along the red lines that you have in your design and marks the surface of the material. The result is crisp but it can be a time consuming technique if you have a lot of small details like text.

Using a combination of both engraving types typically gets the best result. Set your shapes to have a fill color of black with RGB values of 0, 0, 0, the stroke color to red with RGB values of 255, 0, 0, and set the stroke style to a width of 0.01 mm. The line engraving causes the laser beam to trace around the edges of the engraved areas making them more crisp and bringing the details to life.

Typical Uses

Silicone is typically used for gaskets, seals, jewelry, etc.

Adhesives, joints and fastenings

Silicone may be bonded with Sil-Poxy or other silicone based adhesives.

Is it possible to quantify just how stretchy this material is? For instance: how long could you safely stretch a 4 inch wide square to, and how many pounds of force would it take to do it?

Hello! Through our unscientific research here in the laser bay, we have found the following:

0 pounds of force = 4"
5 pounds of force = 6.25"
10 pounds of force = 8"
15 pounds of force = 9.5"
20 pounds of force = 10"

At the 25 pound mark, the silicone begins to permanently deform and break.

Hopefully that gives you a rough idea of this material's elasticity.

That's perfect - exactly what I needed to know. Thank you!

Could someone tell me if this material would be appropriate to make inkable stamps?
Thanks!

Hi Nosheen,

Thanks for getting in touch about this.

We haven't specifically tested this ourselves, so it could be a worthy experiment! You'll need to ensure you cut the silicone material, as the engraving won't be deep enough to miss picking up any ink :)

I hope that helps!

Do you have material Properties? Can this be used as a gasket material?
