What’s the difference between gum and plastic?

What’s the difference between gum and plastic? Plastic and rubber have significant differences in nature, mainly reflected in the deformation type, elasticity, molding process and other three aspects:

(1) Deformation type: when subjected to external force, plastic deformation will occur, that is, it is not easy to return to the original shape or state; The rubber will undergo elastic deformation, that is, it can quickly return to its original state after removing the external force.

(2) Elasticity: The elasticity of plastics is usually small, and its recovery ability after deformation is weaker than that of rubber. Under normal circumstances, the elastic rate of plastics is less than 100%, and the elastic rate of rubber can reach 1000% or higher.

(3) Molding process: plastic in the molding process, once the processing is completed, its shape is basically fixed, it is difficult to change; The rubber also needs to go through the vulcanization process after forming, so that the chemical structure of the rubber is more stable and the performance is better.

In addition to the above differences in nature, there are three differences between gum and plastic:

(1) Composition and source: plastic is mainly processed from fossil fuels such as petroleum and is a man-made material; Gum, on the other hand, is natural, derived from exudates from various trees.

(2) Physical properties: gum usually has a certain viscosity and elasticity, while plastics may have different physical properties such as softness, hardness and brittleness according to the specific type.

(3) Use: Because of its natural viscosity and elasticity, gum is often used for bonding, sealing and other purposes; The application of plastics is very wide, such as packaging, building materials, electronic equipment and so on.

In summary, plastic and rubber have significant differences in deformation type, elasticity, molding process, etc., while gum and plastic are mainly different in composition and source, physical properties and uses. These differences allow us to choose the right materials according to our needs in daily life and industrial production.
