polymer clay is a composite made of polymer (polyvinyl chloride PVC) and inorganic filler, because its performance (soft before baking, hard after baking) is similar to pottery clay, therefore, it is named polymerclay (polymer pottery clay), and there are also polymerclay soft (clay). Compared with pottery clay, it has excellent toughness after baking and is not broken. Chinese people call it polymer clay. We can see the rich expression of Chinese.
Of course, the composition of polymer clay also includes macerating agent (chemical name "plasticizer plastifier"), stabilizer stabliser (or antioxidant antioxidant), lubricant lubricator, colorant dyestuff and color fixing agent dye-fixing agent, etc.
Polyvinyl chloride and inorganic filler are the main components of polymer clay.
PVC, whether imported or domestic, has the same performance as the corresponding brand (including polymerization degree or viscosity, particle size).
