The difference between coupling agent and crosslinking agent

Generally speaking, the term “cross-linking agent” refers to a collection of chemical additives that take part in the cross-linking process of the resin in order to connect the active functional groups in the resin to one another and create a network structure. The working fluid’s viscosity and elasticity may be primarily improved by the cross-linking agent, but it should also have other properties depending on the geological parameters of the reservoir, such as salt and temperature resistance.

The fixability of carbon groups on the surface of organic materials and the reactivity of organic and hydrolyzable groups can both be enhanced by the addition of a modest quantity of coupling agent. adhesive power.

The two are not drastically different from one another, and the coupling agent is a chemical having two functional groups that have various qualities. Their molecules’ functional groups can interact with organic molecules to create bonds or couplings, as well as with adsorbed water or hydroxyl groups on the surfaces of inorganic objects. Bridging and cross-linking agents both have the ability to connect linear molecules into a network structure.

Because of the molecular structure of polymer materials, which resembles long lines, cross-linking agents are primarily employed in polymer materials. Lack of cross-linking results in poor strength, brittleness, and lack of elasticity. The network structure created by the chemical bonds that develop between the linear molecules increases the rubber’s strength and flexibility.

The distinction between a coupling agent and a compatibilizer is as follows:

Although they can both be considered surfactants, their applications differ.

1. The compatibilizer is used to increase the compatibility of the blended polymers, or the compatibility of the two different resins in the polymer alloy, which is typically made by reactive extrusion of synthetic polar polymers and reactive grafts such as polyolefin grafted maleic anhydride, GMA, and other reactive grafts.

2. The 커플링 에이전트 is mostly employed between inorganic and organic materials, and its function is to increase the compatibility between fillers and the molecular chains of resin, resulting in high filler dispersion in the resin
