Always read the instructions because every brand is different. Sometimes the ratio is 1:1 and with other brands the ratio might be 2 parts per hundred. Two parts, A and B, are combined and mixed to create a liquid, pourable molding material. So don’t worry if you have a latex rubber allergy, you won’t have any trouble with silicone rubber. It is not made from natural rubber and therefore does not have the natural rubber proteins that trigger an allergy. There are many, many types and formulations of RTV silicone rubber mold material, but for craft and hobby uses they are available in two general forms, a pourable silicone rubber and a silicone mold putty.īy the way, silicone rubber is an artificial rubber made chemically from a whole soup of elastomers and polymers. RTV silicone consists of two parts that are combined to catalyze a chemical reaction to cause the rubber to “vulcanize” or become polymerized from a very sticky flowing material to a non-stick, stretchy, and durable material. Silicone molds are typically created with something called RTV silicone (for Room Temperature Vulcanizing). Because of the stretchy nature of silicone rubber and the way that it faithfully conforms to the contours of whatever it is touching when it cures, silicone rubber is widely used in making molds of all kinds, for all kinds of materials, including food, medical devices, theatrical makeup, hobbies, and even polymer clay and jewelry components. We all use it every day in things ranging from the clear elastic in our clothes to our muffin pans and potholders to the sealants in our bathroom showers. Silicone rubber is a stretchy material that is widely used in industry and home use and has become very much a part of our lives.
Here’s what I found about silicone rubber mold material. So I’ve done some reading and learning and am passing this information on to you. A trip to the craft store can be even worse because the labels all tell you how great their product is and don’t really tell you how this product is different from the next one. There are so many types and kinds of silicone rubber mold material. But trying to get information online is overwhelming. Silicone molds are becoming more popular in the craft world and you can very easily make your own.
