A crosslinking agent is a substance that joins polymer chains in a chemical reaction. They are widely used in rubber, plastics, coatings, adhesives and other fields to improve the mechanical properties, heat resistance, chemical resistance and other characteristics of materials. This article will focus on two common crosslinking agents, namely, triazine crosslinking agents and epoxy isocyanate crosslinking agents.

Crosslinking Agent TAC is an abbreviation for triazine isocyanate (Triallyl Isocyanurate) and is a commonly used crosslinking agent. It has good crosslinking properties with chloroprene rubber, styrene butadiene rubber, butadiene rubber and other rubbers, and can be used to manufacture rubber seals, hoses, tapes and other products. TAC crosslinking agent is also widely used in wire and cable, welding rod and other fields, which can improve the heat resistance, electrical insulation performance and prolong the service life of the product.

TAIC is an abbreviation for epoxy isocyanate (Triallyl Isocyanurate) and is also a common crosslinking agent. Compared with TAC,TAIC has higher thermal crosslinking activity and can exert better effect at low temperature. Therefore, it is widely used in wire and cable, rubber products, thermoplastics and other fields. TAIC crosslinking agent can improve the heat resistance, weather resistance and hardness of the material, and improve the mechanical properties and chemical stability of the product. The difference between the two crosslinking agents in the application of

is mainly reflected in the following aspects:

1. Temperature requirements: TAC has low temperature requirements, generally crosslinking at 120-150 degrees Celsius, while TAIC can play a better crosslinking effect at a lower temperature.

2. Product characteristics: TAC crosslinking agent can improve the strength, hardness and wear resistance of rubber products, while TAIC crosslinking agent is mainly used to improve heat resistance and weather resistance.

3. Application scope: TAC crosslinking agent is widely used in rubber seals, hoses, tapes and other fields, while TAIC crosslinking agent is suitable for wire and cable, rubber products, thermoplastics and other fields.

To sum up, there are some differences between TAC and TAIC in the application field and effect. According to different materials and product characteristics, choosing the appropriate crosslinking agent can improve the performance of the material and extend the service life. Therefore, when using a crosslinking agent, it is necessary to fully understand the difference between different crosslinking agents and select a suitable crosslinking agent to achieve the best effect.
