Rubber has good elasticity and resilience, can absorb and release energy, and is suitable for making various cushioning materials. In addition, it is waterproof, dustproof and antistatic, so it is popular in some special occasions. In contrast, plastics are low in density, light in weight and easy to carry, but they do not have these characteristics. So rubber is better than plastic.

2. Rubber is a natural material, usually made of latex of rubber tree or other plants. Its molecular structure is flexible and can adapt to different shapes and temperatures. On the other hand, plastic is a synthetic material made of derivatives of fossil fuels such as oil and natural gas. Although it has the characteristics of high temperature resistance and corrosion resistance, in some cases, chemical reactions will occur and harmful substances will be produced. So rubber is better than plastic.
