Zinc oxide used in rubber is one of those essential ingredients needed in the production of rubber products, as it possesses properties that are vitally needed in the manufacture of sophisticated rubber products due to its availability and usefulness.
As such, this remarkable compound is utilized primarily for its chemical and physical properties as well as for other properties which increase the effectiveness, service life and safeness of rubber products. Here are the top five properties of zinc oxide used in rubber.
- Used as Accelerators in the Vulcanization Process
Zinc oxide is one of the important activators used in a process known as vulcanization, where rubber is treated with sulfur in order to make it stronger and more elastic. With the aid of ZnO, the reaction within the mixture is faster, hence it shortens the processing time and the rubber can attain its desired flexibility and strength as required.
- Reinforcement of Rubber
One of the most interesting characteristics of zinc oxide is that it has the capacity of enhancing the mechanical properties of rubber. It increases the tensile strength, tear strength, as well as the abrasion strength of the end product making it suitable in extreme uses like tires and conveyor belts.
- Heat Resistance
Rubber products exposed to high temperatures often degrade over time. Therefore, zinc oxide used in rubber provides heat resistance, preventing thermal aging and ensuring that rubber retains its properties even under extreme conditions. This is especially crucial for applications in the automotive and industrial sectors.
Zinc oxide is an excellent UV stabilizer. It protects rubber products from the harmful effects of ultraviolet radiation, which can cause cracking and degradation. This property is especially valuable for outdoor rubber applications like weatherproof seals and gaskets.
- Antibacterial and Antifungal Properties
In addition to its mechanical benefits, zinc oxide exhibits antibacterial and antifungal properties. This makes it suitable for rubber products used in medical and hygienic applications, where cleanliness is crucial.
Zinc oxide’s unique properties make it an irreplaceable component in the rubber industry. From strengthening rubber to enhancing its resistance against environmental factors, zinc oxide used in rubber ensures the production of high-performance and long-lasting products.
