Introduction to the application fields of high temperature resistant additive zinc acrylate:
Rubber industry, used as a heat-resistant additive:
Tires and seals: By reducing the compression permanent deformation of white carbon black reinforcement rubber, the high-temperature durability is improved.
Shoe material: Improve the heat resistance and resilience of the sole material, and extend its service life.
Vulcanizing agent: accelerates the vulcanization reaction and improves the mechanical properties of the vulcanized rubber, such as tensile strength and elastic modulus.
High resilience products, such as golf ball cores, are obtained by crosslinking polybutadiene rubber to achieve high compressive strength and resilience.
Other industrial sectors:
Adhesive: Used for bonding rubber and metal (such as conveyor belt skeleton materials) to enhance the interfacial strength of composite materials.
Crosslinking agent:
Artificial marble: enhances the weather resistance and structural stability of materials.
Sole material: optimize molding process and enhance anti-aging performance
Storage:
It needs to be stored away from light and moisture (below 25 ℃), and long-term exposure may cause moisture absorption and clumping.
