Tire reclaimed rubber is made from the rubber parts of waste tires as raw materials, processed through crushing, desulfurization, filtration, refining, and other procedures. It retains the basic properties of rubber and is reintroduced into the production of rubber products. Processing waste tires into reclaimed rubber is currently the main method for handling waste tires. Tire reclaimed rubber has good strength, elasticity, and wear resistance, and its applications in rubber products span various industries, including transportation and infrastructure, helping reduce costs.
1. Classification of Tire Reclaimed Rubber
There are many types of tire reclaimed rubber on the market. According to the part of the waste rubber used, it can be divided into tread reclaimed rubber, sidewall reclaimed rubber, and whole-tire reclaimed rubber. Based on strength, it can be divided into high-strength tire reclaimed rubber and ordinary tire reclaimed rubber. According to fineness, it can be divided into superfine tire reclaimed rubber and fine tire reclaimed rubber. According to environmental and odor standards, it can also be divided into environmentally friendly tire reclaimed rubber and odorless tire reclaimed rubber. The performance of different types of tire reclaimed rubber varies significantly, and their uses are different.
2. Application Areas of Tire Reclaimed Rubber
(1) High-strength tire reclaimed rubber: Made from tire tread rubber powder, its main feature is high mechanical strength (tensile strength up to 14MPa) and excellent wear resistance. It can fully or partially replace natural rubber and synthetic rubber to produce black high-strength and high-wear rubber products, effectively reducing raw material costs, such as tire treads and rubber conveyor belts.
(2) Superfine tire reclaimed rubber: Usually made from 80-mesh tire rubber powder, it has high fineness and no impurities, allowing better dispersion in natural and synthetic rubbers. It is mainly used for black molded products or various extruded rubber products that require a smooth surface, such as wire and cable sheaths, thin-walled rubber hoses, rubber strips, and seals, producing rubber products that are darker and shinier than ordinary tire reclaimed rubber.
(3) Environmentally friendly tire reclaimed rubber: Tire reclaimed rubber that passes relevant environmental testing, commonly with EU RoHS certification; the production process of eco-friendly reclaimed rubber is pollution-free and does not contain harmful substances such as lead, cadmium, mercury, or hexavalent chromium. It has the advantages of being odorless, non-permeable, and non-migratory, and is mainly used to produce rubber products with high environmental requirements, such as automotive parts, car interiors, rubber flooring, and rubber soles.
3. Which Type of Tire Reclaimed Rubber is Best?
There are many types of tire reclaimed rubber. Rubber product manufacturers should choose the appropriate tire reclaimed rubber according to the specific needs of their products.
Hongyun Environmental Protection High-strength Tread Reclaimed Rubber is made from 80-mesh and above 900–1200-grade waste tire tread rubber powder. It is processed into fine-ion tire reclaimed rubber through crushing, magnetic separation, desulfurization, filtration, and refining, with characteristics such as high fineness, low specific gravity, high strength, good elasticity, and odorless according to national standards. When mixed with chemical raw materials and left to rest for 12 to 24 hours, it achieves the best effect, significantly enhancing the tear resistance and flexural strength of the rubber products. After being used by thousands of enterprises, it has been shown to significantly reduce rubber raw material costs, save energy, and serve as an ideal raw material for producing high-strength, environmentally friendly extruded rubber products for export.
