What is polymer clay made of?
Polymer clay is a type of modeling material that is made from PVC (polyvinyl chloride) resin and liquid plasticizer. The mixture is then blended with other materials like pigments, fillers, and stabilizers to give the clay its desired properties. The clay can be molded into various shapes and sizes and is often used for creating different crafts, jewelry, and figurines.
The primary ingredient of polymer clay, PVC resin, is a white and odorless powder that is formed by combining chlorine gas and ethylene gas. The resin has the ability to be melted and reshaped repeatedly when heated to specific temperatures. Liquid plasticizer, on the other hand, is typically added to the resin to give it a more pliable and workable texture. It also helps in making the clay soft and flexible.
Properties of Polymer Clay
- Polymer clay comes in a wide range of colors. It can be easily mixed with other colors to create new shades and hues.
- It is non-toxic and safe for handling. It does not contain harmful substances like lead or phthalates, which are commonly found in other types of modeling materials.
- Polymer clay is waterproof and does not degrade easily when exposed to moisture or humidity.
- It can be cured at low temperatures (usually around 265°F or 130°C) in a home oven, making it easy to work with even for beginners.
Longevity of Polymer Clay
Polymer clay can last for a long time if it is stored properly and kept away from heat and sunlight. The clay doesn’t dry out or harden, but if it’s exposed to extreme temperatures, it can become brittle and break. In general, polymer clay will last several years when stored in a cool and dry place. Once the clay is used to create a craft or project, it can last even longer if it is well-cared for and properly handled.
The Bottom Line
Polymer clay is a versatile and popular crafting material that is made from PVC resin and liquid plasticizer. It comes in a variety of colors, is easy to work with, and has a long shelf life when stored properly.
