Rubber Auxiliary Vulcanizing Agent Zinc Acrylate Application Areas:

Rubber Industry:

Auxiliary Vulcanizing Agent: Accelerates vulcanization reactions, improves vulcanization efficiency, and is suitable for high-performance rubber products such as tires and conveyor belts.

Hardening and Reinforcing Agent:

Golf Ball Cores: Used to crosslink polybutadiene rubber, providing high compressive strength and resilience.

Tires and Seals: Enhances durability by improving adhesion between rubber and skeleton materials (such as metal and fiber).

Heat Resistance Additive: Reduces compression set in silica-reinforced rubber compounds for shoe materials and artificial marble.

Other Industrial Applications:

Adhesives: Serves as a bonding medium between rubber and metal, widely used for interface strengthening in composite materials.

Crosslinking Agent: Used in the production of artificial marble and shoe sole materials to enhance structural stability and weather resistance.
