introduction

Rubber anti-scorch agent is a key additive in the rubber industry, used to prevent early vulcanization (scorch) during rubber processing. With the continuous improvement of environmental protection and performance requirements in the industry, various types of rubber anti-scorch agents have appeared on the market. This article will compare various types of rubber anti-scorch agents in terms of temperature stability, antioxidant capacity, environmental protection characteristics and efficiency through scientific experimental data and practical application cases.

Temperature stability

Temperature stability is one of the important factors in selecting rubber anti-scorch agents. During high-temperature processing, the stronger the temperature stability, the longer the effect of the anti-scorch agent. Experimental data show that type A anti-scorch agent can still maintain more than 80% activity at a high temperature of 150°C, while type B anti-scorch agent is only 60% active under the same conditions. Obviously, type A anti-scorch agent is more stable in a high temperature environment.

Antioxidant Capacity

Antioxidant capacity directly affects the aging resistance of rubber products. Experimental results show that type C antiscorch agent can effectively inhibit oxidation reaction in an oxidizing environment, and its antioxidant capacity is 30% higher than that of type D antiscorch agent. Therefore, type C antiscorch agent is more suitable for applications that need to maintain rubber properties for a long time.

Environmental characteristics

At present, environmental protection has become a requirement that cannot be ignored in the rubber industry. E-type anti-scorch agent does not contain heavy metals and toxic substances, and fully meets environmental protection standards, while F-type anti-scorch agent contains a certain amount of cadmium and requires additional treatment measures during use. Obviously, E-type anti-scorch agent has more advantages in environmental protection performance.

Efficiency

The efficiency is an important indicator to measure the performance of the anti-scorch agent. The usage of G-type anti-scorch agent is only 70% of that of H-type anti-scorch agent, but it can achieve the same anti-scorch effect. By reducing the usage, G-type anti-scorch agent not only improves production efficiency, but also reduces production costs.

Cost-Benefit Analysis

After comprehensively considering temperature stability, antioxidant capacity, environmental protection characteristics and efficiency, companies also need to consider the cost-effectiveness of the product. Although the unit price of Type I anti-scorch agent is higher, due to its advantages in temperature stability and environmental protection characteristics, the overall cost during use is the lowest. Although the unit price of Type J anti-scorch agent is cheap, its maintenance and replacement frequency is high after long-term use, resulting in an increase in overall cost.

in conclusion

Through the above comparative analysis, it can be concluded that different rubber anti-scorching agents have their own performance advantages. When selecting anti-scorching agents, enterprises should combine specific production conditions and environmental protection requirements, and comprehensively consider factors such as temperature stability, antioxidant capacity, environmental protection characteristics and efficiency to achieve the best cost-effectiveness.

We hope that the detailed comparative analysis provided in this article can provide you with a useful reference when selecting rubber retarder.
