What Is Silicone Rubber and How Does One Use it?
Obviously, this is quite a broad question. In a sense, it is like asking one to describe how wood or water is used. There are just way too many ways one can use silicone rubber to explain it all in one article. But, if someone has never seen or heard of silicone, you may find it easier to explain the substance to them and give them a pretty decent idea of what it is and how to use it. Here is some interesting history on this wonderful synthetic substance.
Silicone was discovered in 1842 by a man named Jöns Jackob Berzelius. His discovery was made possible because he was experimenting with chlorine solutions. Since that day, humanity has found a plethora of ways to use silicone! Being such a flexible substance that is also quite durable and even somewhat heat-resistant and also airtight, means that silicone will not cause damage to the surfaces it comes in contact with.
Silicone can be used in electronic applications as well as plumbing!
In your home, you will find silicone everywhere! Inside the kitchen, you likely own a pair of silicone oven gloves, baking trays, cupcake molds, basters, containers, and even an egg flipper! When it comes to your car, silicone was used to insulate exposed wires, create gasket sets, and even seal off oil containers. It is also often used to create trim on a vehicle or for the grip on a screwdriver – and then even used to make the container in which your tools are stored inside!
Believe it or not, but, Silicone rubber is even used in the textile and clothing industry. Take for example tee shirts with silicone rubber 3D prints on them, or, shoe soles and even pull strings, zip pull-ring sheaths, and retainers. Other uses are on hairbrushes, retainers, hair tie-backs, and even jewelry like bracelets or earrings.
Our article today, however, is all about one of the biggest uses there is for silicone: Silicone mold kits and resin mold kits. Both of these mold-making kits are available in large and smaller-scale resin casting production. These silicone mold kits can be used to create extremely intricate products (both decorative or practical use items).
One can purchase a silicone mold kit from most supply stores or online from amazon. You can then use these amazing resin mold kits to recreate items inside your home in the form of resin casting. Not only do silicone mold-making kits allow you to recreate items, but they are affordable in comparison to 3D printing.

Understanding Silicone Mold Kit Hardness Grades
As you likely already know, silicone can be both very hard or very soft and flexible. An example of harder silicone is an O-ring, and an example of softer more flexible silicone could be your shoe inner sole. The way this hardness is measured is by using a scale. Every silicone mold kit product will result in its own unique hardness. You will need to select your silicone mold-making kit according to this scale, which will depend on what you wish to use your silicone mold kit for. You should expect a hardness on the shore scale anywhere between 0 to 90. But, how does one determine the level of hardness you will need?
As you can imagine, if you are creating a denser item inside your mold, you should be selecting a resin mold kit that can withstand this material, and therefore, you will require a harder mold. If you use a mold that is too soft and flexible for a heavier product, you will risk your mold breaking, tearing, or losing shape easily. For a better understanding of which shore hardness you will need in your resin mold kit, think of it this way: a shore hardness of 10 is about as softer as a marshmallow would be. A shore hardness of 90 will be as hard and stiff as a human bone.
The latter is of course the stronger option. Make sure you choose the correct hardness for your application, otherwise you risk your silicone mold kit casting coming out incorrectly.
Make sure you read the packaging of your product and read reviews to be certain before you make a purchase.
Using Heat With Silicone Rubber
You might be wondering just how heat-resistant silicone is, and with good reason! While you have likely used and seen silicone rubber used in various applications, you likely are not even aware of how vast its use really is. This includes being used inside machinery and objects that you use every single day! These items rely on their silicone parts to work properly and include things like your motor car, laptop, and cellphone!
So, how much heat is too much and how much of it can silicone rubber withstand? Many silicone rubber molds can, at any degree of hardness, withstand temperatures of up to 302 degrees Fahrenheit (150 degrees Celsius) for up to 10,000 hours. All without bending or losing shape or form. Depending on how the heat is applied and what the quality of the silicone rubber is, the integrity of the silicone will vary. What we mentioned above is a general guideline, set according to researchers. Silicone is not a very good conductor of heat, so it is often an affordable and cheaper way to insulate things.
There is usually a large amount of silicone rubber used inside resin mold kits, and most have very high-quality silicone rubber that can properly withstand higher temperatures.
You need to consider the limitations of your resin mold kits and their reason, depending on the grade used, should you want your molds to last longer.
How to Create a Resin Mold
You should now have a better grasp and understanding of silicone rubber, which will help you select the right resin for your project. Most resin mold kits will come with easy-to-follow and clear instructions, but, should you be unsure, here is a basic guide on how you should use your resin mold kit properly.
Preparation of the Casting Material
You will likely need to combine a two-part formula to create your silicone mold. Most kits will suggest mixing inside a bowl of soapy water, but some are different. This is why following manufacturers’ instructions is so important. The preparation of the casting material is an easy and straightforward process, all you need to do is combine the resin with the hardener in soapy water.
Remember to ensure that they are mixed together properly. When your disk is formed, you will need to compress and decompress the form. Do this until it starts to harden ever so slightly. If you are sure that the consistency is right for what you need, you can remove the resin from the soapy water bowl and get the object you plan on recreating prepared
Putting Your Your Object into the Mold
Your resin mold material should now be ready. You can now place it on a clean and flat surface. The material should still be a flat disk-like shape at this point. You will now need to insert the object you plan on replicating into the mold.
If the item you are replicating is larger or of a more irregular shape, you will likely need to cover it entirely and allow it to set like this.
The main focus should be on making sure you have no gaps between the mold and your object, so make sure it is inside the resin mold as tightly as it can possibly be. When you are absolutely certain that you have no gaps and that your object is nice and firmly indented inside the resin, you can move on to the next step.
Allowing the Resin to Harden and Cure
Various resin mold kits take various times to cure and various times for hardening. As we have mentioned before, check your packaging and instruction insert to be sure. You need to bear in mind that your resin is not going to ever be rock hard and stuff, and this is what you want. It may take many hours, depending on your mold-making kit, for your resin to become more rubbery in its consistency and to lose the slimy feeling and texture.
There are some resin mold kits that take just a few hours to complete this process, while there are some that take 12 or more hours. Again, make sure to check the manufacturer’s guidelines to make sure you are not left with a big sticky and wasted mess. Remember to use only dry hands when your time has lapsed.
Removal of the Object from the Resin Mold
Now it is time to remove the object from the resin mold! This step is very important as you do not want your mold to break or damage at all. Be gentle with this step and your mold should be absolutely okay. Basically, all mold-making kits will state the same thing, whatever you do, do not pull the object out with force! You want to bend the mold away from the object slowly and carefully, eventually allowing your object to pop right out. Do not pry or pull!
Now, your mold should be free of its object and you may need to spray an anti-adhesive before using it. This is to make sure that your mold does not get stuck to your casting material. First, however, give your new mold a rinse with some soapy water, you are now ready to cast your resin!
Well, that wraps up our guide on resin mold kits. You should now have quite a large understanding of silicone rubber, the various hardnesses you may require for your project, and what the best silicone mold kit out there is! We wish you happy mold-making and hope whatever you plan on making comes out exactly as you hoped! Happy Crafting!
