Natural Rubber vs. Vulcanized Rubber: What's the Difference?
Natural Rubber refers to elastic material obtained from latex of rubber trees. Vulcanized Rubber refers to natural rubber chemically treated with sulfur to enhance durability and heat resistance.
Natural rubber is a soft, elastic substance derived from the latex of rubber trees, primarily used in its raw form. Vulcanized rubber, on the other hand, is natural rubber that has undergone a chemical process involving sulfur to improve its properties.
The main characteristic of natural rubber is its high elasticity and flexibility at room temperature. Vulcanized rubber, however, exhibits increased strength, elasticity, and resistance to temperature variations and chemicals.
Natural rubber is more susceptible to temperature changes, becoming brittle in cold and sticky in heat. Vulcanized rubber maintains its integrity and elasticity under a broader range of temperatures.
In terms of applications, natural rubber is used in products requiring flexibility and stretch, like gloves and balloons. Vulcanized rubber is used in more demanding applications like car tires and industrial belts where durability is crucial.
The processing of natural rubber into vulcanized rubber marks a significant advancement in material science, greatly expanding its utility and lifespan in various applications.
