Due to tight supply, Vietnamese rubber prices remain relatively strong, prompting cautious purchasing behavior among downstream buyers. On September 8, the spot price of natural rubber reached 15,416 yuan per ton, marking a weekly increase of 3.06%. Meanwhile, inventories in the Qingdao region fell by 1.66% from the previous week, standing at 592,300 tons, while raw material prices continued to stay high. From January to August 2025, Côte d'Ivoire's natural rubber exports totaled 1.05 million tons, up 14.4% compared to the same period last year. Although export volumes rose year-on-year in August, they declined on a monthly basis as the country continues to adjust its planting structure. In the first half of 2025, the rubber tire industry generally experienced a situation where revenues increased but profits did not—nine companies saw revenue growth, yet their profitability slipped.

Mixing is a critical process in rubber product manufacturing, aimed at uniformly blending raw rubber with various compounding agents—such as fillers, vulcanizing agents, accelerators, and antioxidants—through mechanical shearing. This process produces a compounded rubber that meets specific performance requirements. The quality of the mixing process directly influences both the processing characteristics of the rubber compound and the final physical and mechanical properties of the finished product. This article provides a detailed introduction to the working principles and procedures of both internal mixers and open mills.
Manufacturing Defect Improvement Initiative
Sep 24,2025
Recently, a dedicated improvement team has been established to address long-standing production issues—primarily focusing on products with high defect rates. The team comprises members from departments such as technology, manufacturing, and quality inspection. They hold daily meetings to discuss these challenges, propose targeted improvement measures, assign clear responsibilities, and systematically track and verify the effectiveness of both the improvements and their implementation. The goal is to reduce the defect rate of these persistently problematic products back within the specified acceptable range—and to ensure that continuous improvement efforts can be sustained over time.
Causes and Prevention of Rubber Product Blooming
Sep 24,2025
Scorching refers to the phenomenon where compounding agents in rubber products—such as sulfur, accelerators, antioxidants, plasticizers, zinc oxide, and others—exceed their solubility limit within the base rubber. Alternatively, these agents may migrate to the surface of the product over time due to mechanisms like migration or phase separation, gradually forming a white, frost-like deposit on the material's surface.
