Silicone & Rubber Casting Solutions

We use a variety of materials in our shop and each one serves a slightly different purpose. Below are a few examples of the most commonly used materials. 

​

Urethane Resins

A wide variety of liquid plastic casting resins used for hundreds of different applications. Good for industrial, art-related and hobbyist projects, they are available as rigid or semi-rigid resins. These polyurethane casting plastics are used for making detailed models & prototypes, props and industrial parts. Colors and/or fillers can be added for an infinite variety of casting effects.

 

Urethane Rubbers

Easy to use and exhibiting good wear resistance, polyurethane mold rubber can be poured, brushed on or sprayed onto prepared surfaces and cure with negligible shrinkage. Urethane mold rubbers are economical, reproduce exceptional detail and are best suited for production casting of concrete, gypsum and wax.

 

Silicone Rubbers

Also called condensation-cure silicone mold rubber, these are high-tear silicone mold rubbers that are known as the “work horse” of the industry because of their performance and economy. Tin cured silicone molds are used for casting wax, gypsum, polymer modified gypsum, etc. but are best known for standing up to production casting of urethane, epoxy and polyester resins. They are also good for casting low temperature melt metal alloys.

Silcone Rubbers - Platinum

 Also known as addition-cure silicone mold rubber, platinums exhibit the lowest long-term shrinkage and have the longest library life of all mold rubbers (with a price tag to match). While good for making molds for casting a variety of materials, platinums also have application and physical properties that other rubbers do not. As a result, they are used for other applications. For example, some are certified “skin safe” and can be applied directly to human skin. They are also used for making prosthetic and orthotic devices, skin safe appliances and effects, etc. Some are certified “food safe” for culinary applications.
