  • Packaging may vary* Pourable translucent platinum-cure silicone rubber with Shore 20A Hardness
Bestseller No. 2
Smooth-On Mold Star 15 Silicone Moldmaking Rubber (Pint Unit)
  • Tear Resistant - Mold Star silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage *Packaging may vary*
  • Heat Resistant - Cured Mold Star rubber is heat resistant up to 450°F (232°C) and is suitable for casting low-temperature melt metal alloys
  • Curing - Allow Mold Star 15 SLOW silicone rubber to cure for 4 hours at room temperature (73°F/23°C) before demolding.
  • Vacuum Degassing - Although not necessary, vacuum degassing helps eliminate any entrapped air in pourable silicone rubber
  • Mold Performance - The physical life of the mold depends on how you use it (materials cast, frequency, etc.). Casting abrasive materials such as concrete can quickly erode mold detail, while casting non-abrasive materials (wax) will not affect mold detail. Before storing, the mold should be cleaned with a soap solution and wiped fully dry. Two part (or more) molds should be assembled. Molds should be stored on a level surface in a cool, dry environment

What is Mold Star silicone?

Mold Star 22, 32 & 30 are platinum silicones that are specifically designed for the reproduction of high quality silicone molds. Mold Star 30 is a low viscosity, fast setting silicone that can be easily mixed by hand with no need for strong degassing. Mold Star 22 & 32 are medium viscosities that are ideal for pouring larger molds without trapping air in the mold. They have a short pot life and offer high tear strength necessary for thickness up to 1/4″.

Mold Star 30 has a low viscosity of 27,000 cP and cures overnight. It is specially designed for small molds with high detail that can be poured into a single cavity mold. Its pourable silicone nature allows it to easily penetrate the most intricate of molds.

Mold Star 22 is a medium viscosity platinum silicone rubber compound that features excellent tear strength, good elasticity, and very short pot life. Mold Star 22 can easily produce molds up to 1/4″ thick without trapping air bubbles during the pouring process which makes it perfect for larger projects as well as production casting with minimal cycle times.

Mold Star 32 is a high-strength platinum silicone rubber compound that can produce molds up to 3/8″ (10mm) thick without entrapping air during the pour. It is ideal for projects that require a high-strength, long-lasting mold with minimal shrinkage.

How to use Mold Star silicone?

Silicone rubber has many advantages in comparison to conventional materials, such as high tear strength, good abrasion resistance, and low shrinkage compared to other materials. In addition, it can be processed in a variety of ways and the finished products have excellent resistance to chemicals and weathering. Furthermore, silicone is flexible and has a very low thermal conductivity, which means that it is easy to use on objects requiring heat or cold insulation.

Silicone rubber is supplied as two components: A base component (A) with a catalyst (B), which must be mixed together immediately before use. Silicone rubbers are cured by chemical cross-linking over time. Finally, you end up with a plastic material that still contains no solvents or using agents such as VOCs after curing for several days at room temperature… The advantage of this process is its environmental friendliness compared with substances containing solvents or VOCs.

Silicone can be processed by different means, like brushing, rolling, dipping, pouring, and spraying. Cured silicone rubber is waterproof and has very good resistance to many chemicals (except some oils), high temperatures (>200 degrees Celsius), and UV radiation. It also has low thermal conductivity (0.044 W/(m ˚C)), which makes it best-suited for insulators of heat-producing components in electronic appliances like PCBs (printed circuit boards). The silicone rubber offers thermal insulation properties between -60°C to 260°C (-76°F to 500°F).

Mold Star silicone is specially designed for the manufacture of flexible molds with high dimensional stability for casting gypsum plaster, wax, and low-melt metal alloys. It is extremely flexible and suitable for a variety of other molding applications where a “rubber-like” surface is required.

When designing a new mold the first step should always be to consider whether or not your product can be injection molded. If it can, then this method of production should always be considered as it represents the best value for money process in terms of time and cost savings. We offer our customers CAD files so that they can fully explore their options before contacting us with their requirements…

How does Mold Star silicone work?

Mold Star is a platinum-based silicone mold rubber that cures at room temperature (or cooler) to a Shore hardness of 20. The working time depends on various factors including temperature and humidity, but is typically 30 minutes or more at room temperature. The actual working time may be minutes longer than this depending upon the quantity of rubber used.

What are the benefits of Mold Star?

– Cured rubber is tear-resistant

– Cures at room temperature (or cooler) so no special equipment is required

– Low viscosity formula for easy mixing by hand…no power mixers or vacuum degassing necessary

– 24-hour work time (more than enough for a simple mold)

– 2:1 by volume mix ratio

– 1:1 by weight mix ratio

– Cures to a tough rubber with excellent tear resistance, impact strength and snap after molding

– Rubber stays workable for an extended period of time…up to 24 hours. This allows you to make multiple batches quickly and easily until the correct mix ratio is achieved.

– Low odor level during mixing and working – virtually no offensive odor during cure

– Contains no fillers or additives that would conceivably affect shrinkage or cure times.

– Virtually no shrinkage upon curing which eliminates the need for release agents, parting films, etc. A mere 1% shrinkage is exhibited by Mold Star M20 as opposed to as much as 7% with silicone rubbers containing fillers.


As you can see, silicone molding is a powerful and versatile process that allows for the creation of many things. Whether it’s creating products like candles or soap to make your own custom toys, we hope this post has given you some insight into what Mold Star silicone is all about and how it can be used in various ways around the home.
