Versimold Shelf Life: How Long Will it Last?

Versimold Shelf Life: How Long Will it Last?

We are often asked about the long term stability of Versimold or just how long it can last on a shelf. Firstly, we need to understand what Versimold is (and why that matters).

Think of Versimold as an unfinished product (metaphorically and realistically) because that's exactly what it is. The rubber silicone compound in Versimold is slightly different than the insulation we use for our wire products (Rowe Industries), but chemically they are very similar. On our wire, the silicone rubber is cured fully through a heating process using long room sized ovens. Versimold is packaged without ever being exposed to the heat it would need to cure. With that said, Versimold is susceptible to premature curing if it's not stored properly or if it's exposed to high heat for long periods of time. 

So how should you store it? Pretty simple actually - store Versimold in a cool and dark place that you know won't be exposed to a lot of heat. Some people have had success prolonging the shelf life of Versimold by sticking their pucks in the refrigerator, but we believe this makes the material more difficult to work with.

How long will Versimold last "on the shelf"? If stored properly (see above), Versimold can last well over a year without hardening or partially curing. If Versimold is left unused for periods longer than two years, it will start to mechanically cure and harden. 

We Cure Versimold with Boiling Water

We Cure Versimold with Boiling Water

We recently had a customer tell us that he was able to cure Versimold simply by using boiling water. Since we've always recommended that people use a direct form of heat (such as a heat gun or oven), it didn't take us long to realize that using boiling water would be a perfectly acceptable way of curing Versimold.

Watch our attempt at curing Versimold with boiling water below:

Messiah College Students Develop Ingenious & Inexpensive 3D Printed Prosthetic Hand

Messiah College Students Develop Ingenious & Inexpensive 3D Printed Prosthetic Hand

The clever students (Timothy Gover, Jessica Raboci, and Jason Yoder) at Messiah College's School of Science, Engineering, and Health have developed a prototype of an inexpensive prosthetic hand for children with birth defects or deformities. The ingenious aspect is the simplicity of the design and how economically the prosthetics can be developed.

Using a MarkerBot Z18 Replicator 3D printer with PLA plastic, the students put together the prosthetic hand using a design available from Thingverse, a marketplace for 3D printer designs, Versimold as the flat hinges, and added a curved thumb. The entire hand operates via mechanical wrist actions and allows for enough mobility to improve the overall quality of life for its user.

Just How Strong is Versimold? Let's Find Out!

Just How Strong is Versimold? Let's Find Out!

Selling an interesting product such as Versimold, we often receive questions about the product like "how long does it take to cure" or "does Versimold float?" (it does!). Recently someone asked us a very simple question which we couldn't answer directly: how strong is Versimold? Sure - we could easily direct them to the chemical performance specifications of Versimold (located here), but sometimes we have more fun figuring it out ourselves. And that's exactly what we did in the following video. Now for a disclaimer - this video is not scientific in the slightest and should not be used as a guide, but more as an educational and entertaining video.
