Silicone RTV rubber is a versatile and essential material in the mold making process. It is known for its ability to withstand high temperatures and pressure, excellent tear and tensile strength, and the ability to create precise and detailed molds. However, not all silicone RTV rubber is the same, and different types are used for specific applications.

One of the most common types of silicone RTV rubber is the tin-cured silicone. It is known for its excellent replication properties and easy to use, making it ideal for creating molds for casting and prototyping. It also has a low viscosity, which means it is easy to mix and pour, and it cures quickly.

Another type of silicone RTV rubber is platinum-cured silicone. It is known for its high tear strength and durability, making it ideal for creating molds for products that will be subject to high stress and pressure. It also has excellent chemical resistance and can be used to create molds for casting and encapsulating electronic components.

In conclusion, there are many different types of silicone RTV rubber available on the market, each with its unique properties and applications. It's essential to choose the right type of silicone RTV rubber for your specific project to ensure successful and professional-grade results.
