Which Is Better, Plastic Or Rubber?

• Plastic is a kind of chemical material, is the use of synthetic resins or polymer compounds as the basic raw materials, and add different additives such as plasticizers, fillers, stabilizers, etc., and then processed into different purposes of forming materials. Compared with other materials, plastic has the advantages of light weight, easy molding, low cost, recyclable, etc., and is widely used in packaging, construction, medical, electronics, automobiles, machinery and other fields. Common plastic materials include polyethylene, polyvinyl chloride, polypropylene, polystyrene and so on.
• Rubber is a kind of natural or synthetic polymer material with high elasticity, good water resistance, strong wear resistance and good insulation properties, mainly composed of polymer and other additives, often used to make a variety of rubber products, such as tires, seals, pipes and so on. The natural rubber material is made of latex secreted from natural rubber trees as the main raw material, which is produced through the procedures of harvesting and processing. Synthetic rubber materials are synthesized from raw materials such as petroleum by chemical synthesis methods.

1. Advantages of plastics：

(1) Excellent plasticity and formability: plastic can form various shapes of products at a certain temperature and pressure.

(2) Good acid and alkali resistance and electrical insulation: plastics have a wide range of applications in machinery, electronics, chemical and other fields.
(3) Excellent physical properties: plastics have low density, certain flexibility, good wear resistance and low temperature resistance.

2. Advantages of rubber：

(1) Good sealing performance: rubber has good sealing performance and is often used in the manufacture of seals.
(2) Good wear resistance and aging resistance: rubber has good wear resistance and aging resistance, which is suitable for the manufacture of friction parts.
(3) Cheap and easy to process: The price of rubber materials is relatively low and easy to process.

3.Comparison of plastic and rubber：
Although both plastics and rubber belong to polymer materials, there are some differences in their properties and application ranges:
(1) The difference in material properties: plastic has the advantages of high hardness, high stiffness, good transparency and strong oxidation resistance, while rubber has good elasticity, wear resistance and low temperature resistance.
(2) The difference in processing technology: plastic processing requires high temperature and pressure and is easy to form, while rubber requires hot pressing or injection molding, which is faster and easier to process.
(3) The difference in the field of application: plastic is widely used in daily necessities, electrical appliances, automobiles and other fields, while rubber is mostly used in sealing, suspension, friction parts and other fields.

(4) Different sources of materials. Rubber is mainly derived from natural latex or synthetic polymer materials, while plastics are synthesized from raw materials such as petroleum by chemical synthesis methods.

4. How to distinguish plastic from rubber?

Plastic and rubber differ in appearance, with the most obvious difference being their feel and elasticity.
1. Touch: Rubber usually has a soft texture, while plastic usually feels harder, such as the difference between rubber ducks and plastic mud in toys.
2. Elasticity: The elasticity of rubber is better than that of plastic, and it can be easily stretched and bent, and return to its original shape when released. Plastic, on the other hand, is relatively brittle and prone to cracks.
In addition, there are differences between plastic and rubber in terms of composition. Rubber is usually composed of natural or synthetic polymer materials, while plastic is usually composed of polymer and other additives. Therefore, in industry, rubber is often used to make more flexible and flexible items, such as seals, tires, pipes, etc.; Plastic, on the other hand, is often used to make more fragile items, such as toys, household items, and electronic casing.
 

Taken together, plastics and rubber are very important materials, and their respective advantages and disadvantages and characteristics determine their application in various fields. For different engineering needs, it is very important to choose the right material.
