Rubber additives are chemical substances used to improve the performance and processability of rubber. They are mainly classified into vulcanization accelerators (accelerators, vulcanizing agents, etc.), protective agents (antioxidants, antiozonants, etc.), reinforcing agents (carbon black, silica, etc.), processing aids (plasticizers, softeners, lubricants, etc.) and special agents (colorants, foaming agents, flame retardants, etc.). These additives can enhance the strength, aging resistance, durability of rubber and optimize the production process. They are widely used in tires, seals, medical supplies and other fields.
Main Categories
Vulcanization accelerators: Promote rubber crosslinking and accelerate vulcanization speed, such as accelerators, vulcanizing agents (crosslinking agents), activators, anti-scorching agents.
Protective agents: Delay rubber aging and extend service life, such as antioxidants, antiozonants, anti-flexing agents, light stabilizers.
Reinforcing/filling agents: Enhance hardness, strength, wear resistance and reduce costs, such as carbon black, silica, metal oxides.
Processing aids: Improve processing performance such as mixing, calendering, molding, etc., such as plasticizers, softeners, tackifiers, lubricants.
Special agents: Endow special functions, such as colorants, foaming agents, flame retardants, antistatic agents, antifungal agents, etc.
