Mixing of rubber is to disperse various compounds evenly in rubber with the help of mechanical force of rubber making machine, so as to form a multi-phase colloidal dispersion system with rubber as medium or a mixture of rubber and some compatible components (matching agent, other polymers) as medium, and incompatible matching agents (such as powder fillers, zinc oxide, pigments, etc.) as dispersed phase. process. The specific technical requirements of the compounding process are: uniform dispersal of the compounding agent, so that the best dispersion of the compounding agent, especially the reinforcing compounding agent such as carbon black, is achieved to ensure consistent performance of the rubber. The resulting rubber is called "compounding rubber" and its quality has an important influence on further processing and product quality.

How to improve the temperature resistance of rubber

Resistance to hot air aging or heat aging is becoming increasingly important, especially in automotive applications where rubber parts are mostly used in covered spaces with high ambient temperatures. Automotive manufacturers have felt increasing pressure to commit to longer service lives for their rubber parts. Anaerobic heat aging properties and heat and air aging properties are different. The rubber has better heat resistance, but may still not withstand oxygen attack.

How to reduce the cost of compounding rubber

In the highly competitive world of the rubber industry, the cost of compounding is critical to the economic success of a product. It is possible to develop a compound formulation that meets the customer's needs in terms of both performance, but is rejected by the customer because it is too expensive. In addition, rubber products are generally sold by volume rather than by weight (molded products are generally sized). Therefore, it makes sense to compare the "cost per volume" rather than the "cost per weight" of the rubber.
