Plastic vs. Rubber: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Plastic is a synthetic material made from polymers, widely used for its durability and versatility, while rubber is an elastic substance, obtained either naturally from latex or synthesized, known for its flexibility and resilience.
Key Differences
Plastic is a broad category of synthetic or semi-synthetic materials, characterized by their moldability. Rubber, in contrast, is known for its natural elasticity and is either derived from plant latex or produced synthetically.

Plastics can be thermosetting or thermoplastic, meaning they can either become permanently solid or be remolded. Rubber, while also moldable and flexible, primarily stands out for its ability to return to its original shape after being stretched.

The production of plastic involves the polymerization of organic substances and often includes additives. Rubber, especially natural rubber, is harvested from latex found in certain trees and plants, with synthetic rubber being made from petroleum byproducts.

Plastics are used in a wide range of products due to their versatility and durability, from packaging to construction materials. Rubber is used where flexibility and resilience are required, like in tires, seals, and medical devices.

Plastic has environmental concerns due to its non-biodegradability and potential for pollution. Rubber, particularly synthetic rubber, shares some of these concerns, but natural rubber offers more biodegradable options.
