Rubber formulations contain a variety of ingredients that are also known as compatibilizers. Each component plays a different role in the compound. It is the synergistic action of the various compounds that gives the compound its specific physical and mechanical properties and processing properties.

(1) raw rubber
The main material for the formula, can be a single type of rubber, can also be two or more types of rubber and use, or rubber-plastic compounds. Raw rubber varieties and content in the formula determines the most basic characteristics of the rubber.

(2) Vulcanization system
Including vulcanizing agent, accelerator and active agent. Vulcanizing agents such as sulfur yellow, peroxide, sulfur yellow to the body, etc., in the formulation of the function is to make the rubber macromolecules crosslinked, forming a reticulated three-dimensional structure, so that the rubber has a high strength, elasticity, and other physical and mechanical properties; accelerator in the formulation of the role is to accelerate the rate of vulcanization, shorten the vulcanization time, and its varieties of thiazoles, sulfonamides, Tyulanam, guanidines and thioureas, etc.; the role of the active agent is to The role of the active agent is to increase the activity of the accelerator, also known as co-promoter. The main varieties are metal oxides such as zinc oxide and organic acids such as stearic acid. Vulcanizing agent, accelerator, active agent three synergistic effect of the rubber material to achieve full vulcanization surface with certain physical and mechanical properties.

(3) Reinforcement filling system
Reinforcing agents include various types of carbon black, silica, in the rubber material to play a reinforcing role. Can make the rubber tensile strength, constant tensile stress, hardness and other mechanical properties have been significantly improved.

(4) Protection system
In the formulation of the main function is to prevent rubber products in the storage, storage, use in the process of light, heat, oxygen in the air to produce degradation, or further crosslinking, hardening and other aging phenomena. Its main varieties are various amines and substituted phenol.

(5) Processing aids
Including a variety of operating oil, plasticizer, homogenizer, dispersant, and so on. The function in the formula is mainly to increase the rubber easy to process, reduce energy consumption, promote lubricants, viscosity enhancers, adjusting the hardness of vulcanized rubber and other roles.

(6) Adhesive system
Its function is to increase the adhesion between rubber and skeleton materials such as steel cord, fiber, fabric, such as resorcinol formaldehyde silica system, cobalt salt system, resorcinol acetaldehyde resin (RE) system or resorcinol formaldehyde resin and cobalt salt and other systems.

(7) Other components
Such as colorants, coupling agents, antistatic agents, foaming agents, solvents, etc..
