zinc oxide for rubber

In the rubber industry, zinc oxide is far from an ordinary filler; it is an indispensable key functional additive, hailed as the “heart” of rubber vulcanization. Its quality and performance directly determine the core characteristics of the final rubber products, including durability, strength, and safety. Jiurunfa Chemical Technology Co., Ltd. leverages its specialized chemical production platform and rigorous quality management system to provide the rubber industry with stable, high-performance zinc oxide products. We empower our partners to enhance their product competitiveness.

The core value of zinc oxide for rubber lies in its multiple critical roles during the vulcanization process:

Vulcanization Activator: This is its primary function. Zinc oxide synergizes with accelerators and stearic acid to significantly enhance the speed and efficiency of the vulcanization reaction. It enables rubber to achieve optimal vulcanization in shorter time or at lower temperatures, ensuring full realization of the product's physical properties.

Performance Enhancer: It effectively improves the crosslink density of vulcanized rubber, significantly boosting the tensile strength, abrasion resistance, elasticity, and tear resistance of rubber products.

Heat Conductor and Protective Agent: Its excellent thermal conductivity facilitates uniform heat distribution during vulcanization. Simultaneously, it imparts heat resistance, aging resistance, and UV protection to rubber, extending the service life of the products.

Jiurunfa Chemical Technology's zinc oxide for rubber, produced through refined manufacturing and control, offers the following distinct advantages:

High Activity and Purity: We strictly control the main content and metal impurity levels to ensure high chemical activity. This enables thorough and efficient reactions within the vulcanization system, preventing adverse effects of impurities on rubber compound stability and color.

Optimized Particle Size and Dispersibility: The product exhibits uniform particle size distribution, facilitating easy and even dispersion within rubber compounds. This prevents localized activation imbalances or product defects caused by agglomeration, ensuring a uniform, dense vulcanization network structure and stable performance.

Consistent Batch-to-Batch Stability: We understand the critical reliance of continuous production on raw material consistency. Through standardized production processes and rigorous quality control, we guarantee high consistency in key product metrics across different batches. This provides a solid foundation for downstream customers' production formula stability and reliable product quality.

Jiurunfa Chemical Technology's zinc oxide products are widely used in various rubber goods due to their outstanding performance:

Tire Industry: Used in treads, sidewalls, and liner layers to enhance abrasion resistance, fatigue resistance, and durability.

Industrial Products: Such as conveyor belts, hydraulic hoses, seals, and shock absorbers, enhancing mechanical properties and durability.

Daily-use and Specialty Rubber: Involving rubber shoes, waterproof membranes, and various oil-resistant, heat-resistant specialty rubber formulations.

Jiurunfa Chemical Technology Co., Ltd. is not merely a raw material supplier but a trusted partner. Our professional technical team provides tailored product selections and application recommendations based on customer requirements for natural rubber, synthetic rubber, or specific performance needs. Adhering to the principles of “Integrity, Collaboration, and Mutual Benefit,” we leverage large-scale production and a comprehensive quality control system to deliver cost-effective, consistently supplied products alongside professional and reliable services.
