Traditional eraser materials are mainly made of rubber or other elastic materials, which show good performance when erasing pencil marks. (However, in some specific application scenarios, such as in cold environments, the eraser may affect the use effect due to the hardening of the material. Or long-term high temperature materials will age. In addition, with the improvement of consumers' demand for the beauty and personalization of stationery products, the limitations of traditional eraser materials in color and appearance design have become increasingly prominent, and they cannot be DIY assembled by themselves according to the patterns designed by consumers, and heated and synthesized into one.

[0003] In order to solve the above problems, it is particularly important to develop a rubber material with self-heating characteristics and high aesthetics. By adding various pigments and other additives, consumers' diverse needs for rubber color and appearance can be met. Self-heating materials can, to a certain extent, satisfy consumers' need to design patterns, assemble and heat the rubber themselves, thereby improving user experience.
