AKRON—Shin-Etsu Silicones of America, Inc., has engineered a new type of silicone to make molding houses for rapid 3D prototyping, allowing for improved fabrication speed, easier product revisions, more pulls per mold and reduced production costs, the company said.
The new SES22251 Series of silicone offers high tear strength, high modulus, platinum cure mold-making for urethane, epoxy and acrylic casting.
Shin-Etsu said its SES22251 Series of silicone "is ideal" for uses in medical, automotive and transportation and consumer products, and can be used with undercuts in 3D printing since it exhibits low shrinkage, low viscosity and easy release for the casted product. It can be mixed with four Shore A hardness catalyst options, allowing the mold housing to achieve optimal hardness.
