To understand revulcanized rubber, you first need to understand the vulcanization process and how it affects a rubber's quality and durability.
Let's compare revulcanized rubber with recycled rubber products that haven't gone through the process.
What Is Vulcanized Rubber?Vulcanized rubber has undergone a process called vulcanization. The vulcanization process converts rubber or similar polymers into a more durable and long-lasting product. By using additives, the material is modified and forms a cross-linking structure between the polymer chains. In general, vulcanized materials are less sticky and usually stronger.
Vulcanization uses high-pressure and high temperatures after a curative has been added to the raw rubber material. Using a process of compression molding, the rubber is heated and adopted to the shape of a mold. To cure the rubber, different substances are used. These include sulfur, peroxides and metallic oxides.
Devulcanization and Revulcanization
When tires and other rubber material is no longer needed, it is often scrapped or thrown in the trash. For vulcanized rubber that needs to be recycled, the process of devulcanization is used, which reverses the vulcanization process. However, devulcanization does not result in a material that can be used for many rubber products. Instead, it may need to be ''revulcanized.''
Revulcanized rubber is essentially taking recycled rubber crumbs that have been devulcanized and vulcanizing them all over again, forming a brand new product. Revulcanized materials have many of the same qualities as the original vulcanized rubber, but they are usually not used for tires. Instead, they make a great product for flooring and other products.
Vulcanized Rubber versus Non-Vulcanized RubberVulcanized rubber is ultimately stronger than non-vulcanized rubber. It’s denser and heavier, and when exposed to mechanical stress, vulcanized rubber will return to its original shape once the stress is removed. Non-vulcanized rubber will often be left deformed and can’t return to its original shape.
Vulcanized rubber is non-porous, meaning liquids, like those from a melting water bottle, remain on its surface and aren’t absorbed into the rubber. Vulcanized rubber has a smoother finish and, since it’s non-porous, it can help to reduce bacteria growth.
Keep in mind that non-vulcanized rubber can be plenty strong and durable, but it can absorb liquids and bacteria may form more easily on this type of rubber. Both types of rubber are useful, but they’re best suited for different applications.
