Difference between plastic and rubber

Plastic and rubber are two very common materials in our daily lives; we use them in objects of daily use, in kitchen utensils, in school utensils, in construction, in clothing manufacturing, in the automotive industry, in the food industry, in the footwear industry, among others. At first glance, we might think that both materials are very similar, but the truth is that there are numerous differences between plastic and rubber.

What is plastic?

Plastic is a synthetic material that is obtained from different petroleum derivatives, such as ethylene, propylene, vinyl chloride, among others. The plastic manufacturing process involves the transformation of these derivatives into polymers, through highly complex chemical processes. These polymers can be molded and transformed into a wide variety of objects and shapes. One of the greatest benefits of plastic is that it is strong, flexible and durable.

What is rubber?

On the other hand, rubber is a natural or synthetic material that is obtained from the sap of some trees or plants, or through a chemical synthesis process. Natural rubber is obtained from the Hevea Brasilensis tree, while synthetic rubber is made from polymers such as chloroprene. Rubber is an elastic, resistant and hygienic material, that is used for the production of a huge variety of products.

Main differences between plastic and rubber

• Origin: Plastic is obtained from petroleum derivatives, while rubber can be natural or synthetic.
• Manufacturing: The plastic manufacturing process is much more complex and expensive than the rubber manufacturing process.
• Texture: Plastic is a harder and more rigid material than rubber, while rubber is more elastic and malleable.
• Usage: Plastic is used in the manufacture of more resistant and durable objects, while rubber is used in the manufacture of more elastic and flexible objects.
• Caution: Plastic is more susceptible to damage, while rubber is stronger and requires less care.

Conclusion

In conclusion, plastic and rubber are two materials with very different characteristics and uses. Although both are very useful, it is important to know the differences between them in order to choose the appropriate material according to our needs. In this way, we can ensure that we use the most optimal material for our task or project, guaranteeing better results and greater durability.
