Problems solved by technology

Plastic materials are most closely related to people's lives, and plastic materials are often used to make toys. However, due to the use of stabilizers, plasticizers, and cross-linking agents in the production process of plastic materials, the environment is extremely polluted, and the products cannot Degradation, easy to cause damage to the ecological environment after use
At present, there is no non-toxic and environmentally friendly material that can be completely degraded and has the mechanical properties and performance of ordinary plastics.
