How does conductive rubber work

Now realize the plastic you use everyday is made from this bad to smell chemical. Will adding graphite powder to PlastiDip make a material that is conductive enough to use for an iPhone stylus? Reply 2 years ago. Question 2 years ago. I was wondering if there would be a way to possibly make this firmer sorta like resin? Thank you, and I hope you have a good day!

Question 3 years ago. Will this work for active styluses? I ran out of 2. I wanted to try this instr. It is called Napthalene and was used in Moth-balls, but got ditched because of health-problems And nobody i asked knew a way to thin the silicone So i then headed back home Quite depressed to be honest and tryed some solvents i had at hand.

White spirit, petrol, universal-laquer-thinner, All gave a major mess and didnt really thin out the silicone. I found on the nets, that some solvents are also able to thin silicone: toluol and xylol, but both are de facto banned due to health-concerns. An alternative is cyclohexan German name, dont know eng , but it is hard to get hold of it.

Then i found some guys who make roll-on-silicone for theyr projets and the use turpentine or Mineral turpentine to thin the silicone to a thin paste to roll-on.

Will try this in the evening, since turpentine is quite cheap and freely available. Will report back. Reply 3 years ago. Reply 4 years ago. It sounds like you're not in the US. I can head over to my fantastic locally owned hardware store and buy xylol and naphtha as well as other solvents.

Never suggest economy killer walmart. I notice a lot of solvents are associated with, but not exclusive to particular technologies or materials like fiberglass.

Maybe you can find specialty suppliers for some of the solvents you can't find locally to you. Turpentine sounds horrible as a substitute since it's slow drying. How about acetone? I'm happy I found this to experiment with pens and other things I already have.

Welcome from the past! It stayed clumpy as the other solvents i mentioned. Turpentine was much better. And the slow-dry was no problem. Makes it much easyer to work with to be honest Reply 9 years ago on Introduction. Just to clear up some confusion. Naphtha and Naphthalene are not necessarily the same thing.

Naphthalene was used in moth balls and is solid at room temperature. It is obtained primarily from coal tar. Naphtha liquid is a mixture of hydrocarbons obtained from oil distillation. It is used for camp stoves, lanterns, lighters, and as a general solvent. It is also known as Shellite or Recosol R55 in Australia. Wikipedia has some links to manufacturers MSDS sheets. You could try camping supply shops for the stove fuel though some stoves use Kerosene or Methylated Spirits.

Unfortunately very few, if any, solvents are competely safe. Turpentine works great for thinning silicone. It started clumpy like the other solvents, but got smoother really fast. Here is a trick on how to mix it best: 1. Easy to see now since it is still a clear paste. Question 3 years ago on Step 4. I do not understand about the drill bit. I can't find a drill bit in any of the pictures.

BUT, I love your work. Lost Your Password? Username or E-mail:. Use of Conductive Rubber Conductive rubber finds use in multiple industries, including computing, military, medical devices, and telecom sector. Tags: conductive rubber. Related post. Enclosure Shielding Gaskets 07 Dec , Enclosure Shielding Gaskets 14 Sep , See Figure 1. In Conductive Elastomer the base rubber is usually comprised of compounds such as silicone, fluorosilicone, or EPDM ethylene propylene diene monomer.

The use of a specific rubber is based upon the properties unique to each and determined by the intended environment and application. For example, silicone is used for general weather sealing and high temperatures to deg. Fluorosilicone is used for applications where exposure to jet fuel, gasoline, and alcohols are present.

After choosing a specific rubber suited for the intended environment, a conductive filler must be determined. Some of the most common conductive metal fillers used are silver aluminum, silver glass, silver copper, and nickel graphite. Determining the right filler is dependent on the level of shielding needed for a specific application, the more conductive the filler the higher the level of shielding achieved.

Once the parameters have been determined, the table below can be used to establish which Conductive Elastomer is right for the application. Radthin: While not as popular as either the Multicon or Conductive Elastomer materials, the Radthin gasket material can be a valuable asset when an ultra thin gasket that can withstand a wide-range of temperatures is needed. Often seen as a common gasket for connectors it can also be die-cut into custom shapes for other unique applications.

Radthin is comprised of a 24 mesh aluminum alloy wire cloth impregnated with 50 durometer neoprene or silicone rubber compound. The total thickness of either the silicone or neoprene Rathin is either 0. The temperature range of the neoprene Rathin gasket is deg.

F to deg. F, the silicone Radthin is deg. This makes it ideal in certain settings. See Figure 3. Figure 3 Radthin material — 24 mesh aluminum alloy wire cloth impregnated with 50 durometer neoprene or silicone rubber compound. Galvanic compatibility is the corrosion potential between the conductive material and the metal interface or mating surface. In some cases, one side of the material may be exposed to a different metal than the other; in this case, a conductive wire type or filler choice needs to be made where the difference in voltage potential between the dissimilar metals are as small as possible.
