Natural Rubber vs. Vulcanized Rubber — What's the Difference?
By Tayyaba Rehman — Published on November 17, 2023
Natural Rubber is a polymer made of isoprene units sourced from latex in certain plants. Vulcanized Rubber is Natural Rubber that's been chemically processed with sulfur to enhance its properties.

Key Differences
Natural Rubber has been in use for thousands of years. Derived from latex found in certain plants and trees, particularly the rubber tree, it's a polymer made primarily of isoprene units. On the other hand, Vulcanized Rubber is a more modern invention. While it starts with Natural Rubber as its base, it undergoes a chemical process involving sulfur to enhance its durability and other properties.
When you think of Natural Rubber, consider its raw properties. It's soft, quite stretchy, and is affected by temperature changes. This makes it versatile for certain applications but not ideal for all. Vulcanized Rubber was developed in response to these limitations. By adding sulfur and applying heat, the rubber undergoes a transformative process, making it tougher, more elastic, and more resistant to wear and tear.
Natural Rubber has its advantages, such as high elasticity and the ability to recover its original shape after stretching. However, without treatment, it can degrade quickly when exposed to environmental factors like UV rays. Conversely, Vulcanized Rubber offers enhanced resistance to environmental factors, making it ideal for applications like automobile tires, shoe soles, and various other products.
One interesting feature of Natural Rubber is that it's biodegradable. Being a naturally derived material, it breaks down over time, returning to the environment. Vulcanized Rubber, after undergoing its chemical change, takes significantly longer to degrade. This longevity can be both an advantage and a concern, especially when considering environmental impacts.
While both Natural Rubber and Vulcanized Rubber have their unique places in industry and manufacturing, they serve different needs. Natural Rubber is best when a softer, more malleable material is required. In contrast, Vulcanized Rubber's enhanced properties make it the choice for applications demanding increased durability and resilience.
