Product Overview of Nano-Silica for Tire Rubber This product is a nano-sized silica independently developed by Zhongqi Guangdong Silicon Material Co., Ltd., specifically customized as a high-performance rubber additive to address the core pain points in the tire manufacturing industry: "balancing wet skid resistance, wear resistance and rolling resistance while improving rubber processing performance". Based on the unique advantages of nano-sized particle size and precise process control, the product not only optimizes the comprehensive mechanical properties of tire rubber but also enhances the durability and safety of tires, while meeting the global requirements for energy conservation and environmental protection. It is widely used in the production of passenger car tires, commercial vehicle tires, engineering tires and other rubber products, and is exported to Southeast Asia, Europe, America and other international markets. II. Core Product Advantages 1. Excellent Comprehensive Tire Performance Enhancement The product can significantly improve the three key performance indicators of tires: it enhances wet skid resistance by more than 30% to improve driving safety on rainy days, reduces rolling resistance by 15%-25% to achieve energy conservation and fuel efficiency, and increases wear resistance by 20% to extend tire service life. Its core mechanism lies in the uniform dispersion of nano-sized particles in the rubber matrix, which forms a stable cross-linking network, effectively improving the toughness, elasticity and wear resistance of rubber, and solving the contradiction between traditional additives that cannot balance multiple performance indicators. 2. High Purity and Excellent Compatibility Strictly adhering to the industrial standards for tire rubber additives, the product has high purity (silica content ≥99.8%) and extremely low impurity content, fully complying with ISO/TS 16949 automotive industry quality management system standards and relevant European and American environmental protection regulations. It has excellent compatibility with natural rubber, synthetic rubber (SBR, BR, EPDM, etc.) and other rubber additives (carbon black, vulcanizing agents, accelerators), without affecting the vulcanization process of rubber, and can be directly mixed and used in the tire production process. 3. Strong Reinforcement and Processing Performance Relying on the large specific surface area and unique surface activity of nano-sized particles, the product has strong rubber reinforcement performance, which can improve the tensile strength, tear strength and modulus of elasticity of tire rubber. At the same time, it can optimize the processing fluidity of rubber compounds, reduce the mixing energy consumption, improve the uniformity of rubber mixing, and effectively solve the problems of rubber agglomeration and poor processing performance during production. 4. Flexible Customization Capability It supports particle size customization service in the range of 10-100nm. According to the performance requirements of different types of tires (such as high-performance passenger car tires, heavy-duty commercial vehicle tires, off-road engineering tires) and rubber formula characteristics, it can provide personalized product solutions with high adaptability to meet diverse application scenarios and performance needs. 5. Full-Cycle Service Guarantee It provides comprehensive pre-sales and after-sales technical support. Pre-sales samples can be provided for customers to conduct rubber mixing and performance testing. After-sales, a professional technical team is equipped to provide guidance on product mixing ratio, vulcanization process optimization and other aspects, solve various technical problems encountered by customers in the application process, and ensure that the product performance is fully exerted. III. Production Strength Guarantee Zhongqi Guangdong Silicon Material Co., Ltd. has been deeply engaged in the silica industry for more than 20 years. As a national high-tech enterprise and a provincial-level specialized, refined, unique, and innovative enterprise, it provides a solid guarantee for product quality. The company has 17 patented technologies and a GMP-certified production base, equipped with advanced testing equipment such as atomic fluorescence spectrometers, laser particle size analyzers and rubber performance testers. It has established 26 full-process inspection procedures covering raw materials, semi-finished products to finished products, and has obtained ISO/TS 16949 automotive industry quality management system certification and ISO 14001 environmental management system certification, realizing full-chain standardized control from R&D, production to quality inspection. IV. Packaging and Transportation Specifications 1. Standard Packaging Specifications Adopting a standardized packaging design, it provides 20kg, 25kg, and 50kg woven bag packaging options to meet different order quantities and transportation needs. The packaging is sturdy and durable, which can effectively prevent damage during transportation. 2. Professional Waterproof and Moisture-Proof Design To ensure the stability of the product during transportation and storage, a dual waterproof and moisture-proof protection solution is adopted: Solution 1 is composite film valve bag + outer PE film; Solution 2 is PE inner film bag + plastic woven bag. It provides all-round protection against moisture intrusion, prevents the product from dampening and agglomerating, and ensures the stability of product performance. 3. Storage and Transportation Requirements - Storage conditions: Should be stored in a cool, dry and well-ventilated warehouse, avoiding direct sunlight, humid environment and high temperature; it should be placed separately from corrosive substances. - Shelf life: 24 months under suitable storage conditions. - Transportation attribute: The product is a non-hazardous chemical, supporting multiple transportation methods such as sea freight, land freight and air freight worldwide, which can be safely delivered to the designated locations of domestic and foreign customers. During transportation, avoid rain, moisture and severe collision. 24. Standard Labeling Each batch of product packaging is strictly marked with legal information such as rubber additive attribute, particle size specification, production date and production license number; at the same time, label styles can be customized according to customers' personalized needs to ensure compliance with the regulatory requirements of different markets. V. Applicable Application Fields The product is mainly suitable for the tire manufacturing industry, especially for the production of passenger car tires (high-performance tires, energy-saving tires), commercial vehicle tires (truck tires, bus tires), engineering tires (off-road tires, mine tires) and other tire types. It can also be extended to other rubber products that require reinforcement and performance improvement, such as rubber seals, conveyor belts and rubber hoses. With its excellent comprehensive performance and stable quality, it is widely recognized by domestic and foreign tire manufacturers. VI. Conclusion Zhongqi's nano-silica for tire rubber is positioned at the core of "optimizing tire performance, saving energy and environmental protection, and ensuring driving safety". Relying on strong R&D capabilities, strict quality control and a complete service system, it provides one-stop additive solutions for tire manufacturing enterprises.
