Crosslinking agent is a substance that connects polymer chains in chemical reactions. 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

TAC is an abbreviation for Triallyl Isocyanate, a commonly used crosslinking agent. It has good cross-linking properties with various rubbers such as chloroprene rubber, styrene butadiene rubber, and butadiene rubber, and can be used to manufacture rubber seals, hoses, tapes, and other products. TAC crosslinking agents are also widely used in fields such as wires and cables, welding rods, etc., which can improve the heat resistance and electrical insulation performance of products, and extend their service life

TAIC is the abbreviation for Triallyl Isocyanate, which is also a common crosslinking agent. Compared to TAC, TAIC has higher thermal crosslinking activity and can perform better at low temperatures. Therefore, it is widely used in fields such as wires and cables, rubber products, and thermoplastic plastics. TAIC crosslinking agent can improve the heat resistance, weather resistance, and hardness of materials, as well as improve the mechanical properties and chemical stability of products

The difference between the two crosslinking agents in application is mainly reflected in the following aspects: 

1. Temperature requirement: TAC has a lower temperature requirement, generally crosslinking at 120-150 degrees Celsius, while TAIC can achieve better crosslinking effect at lower temperatures

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 wires and cables, rubber products, thermoplastic plastics and other fields

In summary, there are certain differences in the application fields and effects between crosslinking agents TAC and TAIC. Choosing appropriate crosslinking agents based on different materials and product characteristics can improve the performance of materials and extend their service life. Therefore, when using crosslinking agents, it is necessary to fully understand the differences between different crosslinking agents and select suitable crosslinking agents to achieve the best effect.
