8 advantages of using reclaimed rubber in rubber products

Recycled rubber, that is, waste vulcanized rubber is crushed, heated, mechanically and chemically treated and other physical and chemical processes, so that it changes from an elastic state to a certain plasticity and viscosity, and can be processed and re-vulcanized rubber. The main raw materials of reclaimed rubber are waste tires, rubber shoes, rubber hoses, adhesive tapes, industrial rubber and scrap of rubber products during vulcanization, which are mainly used to replace high-priced raw rubber to produce rubber products and reduce manufacturing costs.
In actual production, reclaimed rubber is widely used in tires, car tires, rubber shoes, hoses, tapes, rubber sheets, waterproof coils, coatings, linoleum and other production, rubber products using reclaimed rubber mainly has the following 8 major benefits:
① Reclaimed rubber cheap to reduce raw material costs
Compared with the original rubber, the reclaimed rubber product price is very low. The average rubber content of reclaimed rubber is about 50%, and the rubber hydrocarbon content of high quality latex reclaimed rubber can reach more than 75%. The reclaimed rubber contains antioxidant, softener, zinc oxide HYL2Y8YEE and carbon black which can be reused. The tensile strength of reclaimed rubber can reach more than 9-10MPa, the tensile strength of high-strength latex reclaimed rubber can even reach more than 18MPa, and the tensile strength of tire tread reclaimed rubber can reach 15MPa.
The rational use of reclaimed rubber in the production of rubber products can not only ensure product quality, but also effectively reduce the cost of raw materials.
② Reclaimed rubber has good plasticity
Reduce production energy consumption reclaimed rubber has good plasticity, easy to mix with raw rubber and compounding agent. When rubber products are mixed with reclaimed rubber for mixing, not only the quality of the compound is uniform, but also the man-hours can be saved and the power consumption can be reduced.
③Mixing reclaimed rubber to reduce heat generation and avoid scorching
The use of reclaimed rubber in rubber products can reduce the heat generation in the processes of mixing, hot mixing, calendering, extrusion, etc., so as to avoid the scorching of the rubber material caused by the high temperature of the rubber material, which is particularly important for the rubber material with high carbon black content.
④ Reclaimed rubber has good fluidity
In the production process of rubber products mixed with reclaimed rubber to improve the shrinkage of rubber materials, the fluidity of rubber materials is good, so the calendering and extrusion rates are fast, the shrinkage of pressure delay and the expansion of extrusion are small, and the appearance defects of semi-finished products are few.
⑤ The thermoplastic of the compound mixed with reclaimed rubber is small, so it is easy to maintain the original shape during molding and vulcanization.
The vulcanization rate is fast, and the tendency of vulcanization to return to the original is small.
⑦ The appropriate amount of reclaimed rubber used in rubber products can improve the oil resistance and acid and alkali resistance of the products.
⑧ The reclaimed rubber has good aging resistance. A certain proportion of reclaimed rubber mixed in the rubber product formula can improve the natural aging resistance and heat oxygen aging resistance of the product.
The benefits of the rational use of reclaimed rubber in the production of rubber products do not stop there. At present, the common reclaimed rubber on the market includes latex reclaimed rubber, tire reclaimed rubber, high strength reclaimed rubber, nitrile reclaimed rubber, butyl reclaimed rubber, ethylene propylene diene monomer reclaimed rubber, styrene butadiene reclaimed rubber, cis butyl reclaimed rubber, neoprene reclaimed rubber, etc. Different varieties of reclaimed rubber have different physical properties. Rubber product manufacturers must select appropriate reclaimed rubber and mix it into rubber products in an appropriate proportion to further optimize the quality while reducing cost.
