The different kinds of silicone putty include two-part silicone mold putty, silicone lab putty, all-purpose putty, and food-grade silicone putty. One of the most popular is the two-part silicone mold putty; another very popular silicone putty is food-grade putty. There are many different uses for these putties.

Two-part silicone mold putty, which is non-toxic, can be used for creating simple models. Such models are reusable and flexible, and can withstand up to 600° F(about 316° C) of heat. This type of putty can also be used with other materials to make miniature doll figurines and doll house furniture. Two-part silicone putty does not require very much time or skill, and it's ideal for amateur model makers.

Silicone lab putty is used in dentistry. Other types are used, but this type has been among the most popular. This putty is used to make dental impressions. The putty hardens and gives the dentist the ability to see what kinds of crowns, dentures, or porcelain veneers would fit someone's teeth.

All-purpose putty is used to to fill and patch PVC pipes. It can also be used for ceramic, tile, and laminate. It can be used on driveways, walls, broken chimneys,knot holes, shingles, and more. This putty is mainly used for repairs inside or outside the house.

Food-grade silicone putty is similar to two-part silicone putty, although food-grade silicone putty is actually edible. Once the mold is made, it can be used with butter, chocolate, edible cake decorations, and more. It can also be used to make hard candy or caramels.

Most silicone putties are widely available for purchase. The best place to find two-part silicone mold putty and food-grade silicone putty is at a local craft store or online. All-purpose putty can be found at most home improvement stores.
