                                                                                                  Addition-curing casting rubbers are a special class of silicone rubber that, after curing, deliver a beautiful, rubber-like, and flexible result. Here are some key features:

                                                                                                  1. Curing: These silicones cure through a reaction with a platinum catalyst. This process ensures a stable and durable structure.

                                                                                                  2. Flexibility: Addition-curing casting rubbers are highly flexible and can be easily deformed without losing their integrity.

                                                                                                  3. Durability: They remain durable for many years and do not shrink after curing.

                                                                                                  Applications of Addition-Curing Casting Rubbers:

                                                                                                  • Skin-Friendly: This type of silicone is often suitable for skin contact and does not shrink. Special versions can even be used as molds for food items like chocolate or cake.

                                                                                                  • Creative Uses:
