In the tire manufacturing process, rubber additives account for a large proportion of the raw material cost.
Among them, industrial-grade indirect zinc oxide is a core component of the vulcanization system, and its procurement cost and usage efficiency directly affect the overall production cost of the enterprise.
For the person in charge of procurement, how to effectively control the total usage cost of zinc oxide while ensuring product quality is an important issue that requires long-term attention.
Currently, many tire companies still use the traditional zinc oxide usage scheme, which has many cost issues.
First of all, the dosage is relatively large. The dosage of zinc oxide in traditional formulas is generally about 5 parts.
Since ordinary zinc oxide has low activity, the dosage must be increased to ensure the vulcanization effect, which directly leads to an increase in raw material costs.
Secondly, the stability of each batch of products is not good, and different batches of zinc oxide have differences in purity, particle size, activity, etc., which will cause fluctuations in the performance of the rubber material.
In order to ensure product quality, companies often need to leave a large safety margin, further increasing the amount of zinc oxide.
Finally, the scrap rate brings losses. The unstable quality of zinc oxide or improper use will lead to a decrease in the physical and mechanical properties of the rubber after vulcanization, and problems such as insufficient vulcanization and over-vulcanization, which will increase the number of scraps and bring additional losses to the company.
High-quality industrial-grade indirect zinc oxide, controlled by advanced production processes, has the characteristics of high purity, good activity, and uniform particle size, which can bring significant cost reduction space for tire companies.
The overall cost comparison of different zinc oxide solutions is as follows: the purchase price of ordinary zinc oxide is lower, but the dosage is large, the batch stability is poor, the scrap rate is high, and the overall cost of use is high; the purchase price of industrial-grade indirect zinc oxide is moderate, the activity is high, the dosage can be reduced, the batch stability is good, the scrap rate is low, and the overall cost of use is more cost-effective; the purchase price of nano zinc oxide is high, although the dosage can be further reduced, but it is difficult to disperse, easy to form agglomerates, and the overall cost-effectiveness is not high.
Using good quality industrial-grade indirect zinc oxide, tire companies can appropriately reduce the dosage of zinc oxide while ensuring the vulcanization effect.
At the same time, due to the good stability of product batches, it can reduce the loss of scraps caused by performance fluctuations and help customers obtain long-term and stable production profits.
When selecting an industrial-grade indirect zinc oxide supplier, the person in charge of procurement should not only focus on the product purchase price, but should comprehensively consider the following key factors.
The first is the stability of product quality. Stable product quality is the basis for ensuring production continuity and product quality. Choosing companies that have passed ISO9001 quality management system certification can obtain more reliable quality assurance.
The second is technical service capabilities. Excellent suppliers can not only provide high-quality products, but also provide customers with technical support such as formula improvement and process optimization to help customers solve practical problems in production.
The third is the ability to guarantee supply. Suppliers with direct sales from manufacturers and sufficient stocks can ensure timely supply and avoid production interruptions due to shortages of raw materials. Long-term and stable cooperative relationships can also help obtain more favorable purchase prices.
In 2026, the new energy vehicle market will continue to grow rapidly, and the demand for new energy tires will continue to rise.
New energy tires place higher requirements on the heat resistance, durability, and low rolling resistance performance of additives.
Good quality industrial grade indirect zinc oxide can effectively improve the comprehensive performance of tires and meet the special needs of new energy tires.
