Thermoplastic beads, sometimes called moldable plastic pellets or InstaMorph, are small granules made from a polymer that softens when heated and hardens when cooled, without undergoing chemical change. In essence, they behave like a reusable plastic clay: when warmed above a certain temperature, the reusable polymorphic beads become pliable and can be molded; when cooled back to ambient temperature, they solidify into a rigid shape. This reversible phase change is characteristic of thermoplastics in general.
These thermoplastic pellets are composed of a polymeric plastic with a low melting point and are perfect for use in crafts, cosplay, small repairs, prototypes, and dental or theatrical effects (such as fangs) due to their ease of use, reusability, and ability to adopt fine details.
This product cannot be painted very well, meaning that it practically repels all paints. You could paint pieces to use in a costume or cosplay prop, but keep in mind that the paint could scratch easily if those parts rub against something. It is best to paint it with airbrushing and always apply an acrylic primer to improve adhesion.
One of the appealing features is that once cooled, they are stable and retain shape until reheated. This makes them ideal for repeated adjustments or remolding.
