Customer information: Shandong Qingdao XX Rubber Products Factory
Products used: Hongyun 1# white latex reclaimed rubber, 100% black latex reclaimed rubber
Products manufactured: Bicycle tire tread rubber
Case Background:Shandong Qingdao XX Rubber Products Factory mainly produces bicycle tires, colored bicycle tires, and related rubber products, with products primarily targeting the domestic bicycle supply and maintenance market. As competition in the bicycle tire market intensifies, customers have higher requirements for the color, wear resistance, elasticity, and production cost of tread rubber. Especially for colored bicycle tires, using ordinary black reclaimed rubber can easily affect the tread color and appearance, and using only natural or synthetic rubber leads to higher raw material costs.
Latex reclaimed rubber is made from waste natural rubber, waste latex, and its products, retaining the basic properties of natural rubber, offering high strength, good elasticity, and excellent processing performance. It is compatible with natural rubber E6LYY617 and some synthetic rubbers. Using an appropriate amount of natural latex reclaimed rubber in bicycle tire tread rubber formulations can reduce the amount of raw rubber used and lower overall formulation costs. After comparison and testing, manufacturers chosen Hongyun #1# white latex reclaimed rubber for colored bicycle tire tread rubbers based on production needs for different tire colors, and 100% black latex reclaimed rubber for black bicycle tire tread rubber.
Needs Analysis:For colored bicycle tires, customers focus on color stability and tread appearance. Hongyun #1 white latex reclaimed rubber has a lighter color, making it easier to match with white, red, yellow, blue, and other colored rubbers, and unlike black reclaimed rubber, it does not noticeably affect the finished product's color, making it more suitable for use in colored bicycle tire tread rubber. When designing the formula, the addition ratio of white latex reclaimed rubber can be adjusted according to color, hardness, and wear resistance requirements.
Black bicycle tires should be made of 100% black latex reclaimed rubber, which can fully utilize the reclaimed rubber's color and better processing properties. Compared to the black tread rubber formula produced from pure natural rubber, adding a certain proportion of black latex reclaimed rubber can reduce the amount of natural rubber used, improving the plasticity and processing performance of the compound.
Usage Effects:After multiple small-scale, pilot, and mass production verifications, colored bicycle tire tread colors produced using Hongyun #1 white latex reclaimed rubber have uniform color, good rubber dispersion, and excellent extrusion processing performance; black tread rubber produced with 100% black latex reclaimed rubber has a stable appearance and moderate plasticity, meeting the production requirements for bicycle tire tread rubber.
Compared with traditional formulas that use only natural and synthetic rubber, the reasonable addition of latex reclaimed rubber effectively reduces the amount of raw rubber used while ensuring the basic physical properties and usage requirements of tread rubber, and significantly lowers the overall cost of raw materials. Latex reclaimed rubber has excellent reprocessing performance, which can improve the processing state during compound mixing and extrusion, which helps increase production efficiency.
Case Summary:Using latex reclaimed rubber to produce bicycle tire tread rubber offers the following six advantages.
1. Lower formulation costs. Latex reclaimed rubber has a higher price advantage compared to natural rubber and some synthetic rubber. With reasonable control of the addition ratio, it can replace part of the original rubber and effectively reduce the raw material cost of bicycle tire tread rubber.
2. Colored tread color matching is more convenient. White latex reclaimed rubber is light in color and contains fewer impurities, making it suitable for use in red, yellow, blue, green, and other colored bicycle tire tread rubbers. It reduces the impact of reclaimed rubber color on the final product color and makes subsequent color matching more convenient.
3. Black tread can be made with black latex reclaimed rubber. For ordinary black bicycle tires, 100% black latex reclaimed rubber can be used, combined with natural rubber or synthetic rubber according to product performance requirements, reducing costs while meeting the processing and usage requirements for tread rubber.
4. Improves the processing performance of the compound compound. Latex reclaimed rubber has a certain degree of plasticity and good mixing and processing properties. When properly added, it helps with mixing, extrusion, and molding, thereby improving the processing state of the compound compound.
5. Facilitates differentiated product production. According to the color and performance requirements of bicycle tires, white latex reclaimed rubber and black latex reclaimed rubber are used respectively. Formulas can be adjusted for colored and black tread, meeting the production needs of different markets while controlling costs.
6. Enhance product market competitiveness. Bicycle tires are rubber products with significant price competition. Using latex reclaimed rubber reasonably while ensuring tread rubber performance can reduce overall manufacturing costs and give companies greater price advantages in the markets for colored tread and ordinary black tread products.
In actual production, manufacturers of bicycle tire tread rubber can adjust the amount of latex reclaimed rubber, carbon black, softeners, vulcanization systems, etc., based on the tread color, hardness, tensile strength, elongation at break, wear resistance, and extrusion appearance during trial production, so that the rubber meets extrusion requirements while reducing costs while maintaining the performance of the tire tread.
