Applicable fields: textile, daily chemicals, lubricating oil

Main application fields
Based on the functions of oleamide and adipic acid derivatives, their core uses are inferred as follows:
1. Polymer material processing AIDS
Lubricant/slip agent: Migrates to the surface of plastics (such as PE, PP), reduces the friction coefficient of the film, and improves the opening property (refer to the application of oleamide in packaging materials).
Anti-adhesive agent: Prevents polymer layer adhesion and enhances processing efficiency.
Dispersant: Used in color masterbatches or filling systems to promote the uniform dispersion of pigments/fillers (such as the role of stearamide in color masterbatches).
2. Surface treatment and coatings
Anti-slip/wear-resistant agent: Added to coatings (such as automotive topcoats) to enhance surface smoothness and reduce scratches (similar applications of oleamide).
Waterproofing agent: Long-chain alkyl groups can endow fabrics or fibers with hydrophobicity (refer to the waterproofing function of stearic acid amide).
3. Other industrial fields
Rubber additives: Improving the fluidity of mixing and the demolding property of products (the plasticizing effect of adipate esters in rubber).
Metalworking fluid: As a lubricating additive, it reduces friction and wear (analogous to the application of diethanolamide oleate in cutting fluid).
Textile auxiliaries: If flexibility and surface activity are required, reduce the surface tension of fibers to make the fabric fluffy and soft, and lower the friction coefficient between fibers to make the fabric smooth.
Iv. Functional Features and Advantages

Characteristics	Mechanism of action	Application scenario example

N,N' -dioil-based adipic acid amides are a type of functional dicamides with surface modification capabilities. Their core value lies in:
① Achieve the smoothness and anti-adhesion of plastics through molecular migration;
② As an environmentally friendly additive to replace silicon-containing products;
③ It can be expanded to be applied in multiple fields such as coatings and textiles.
In the future, performance can be further optimized by modifying the amino structure (such as introducing hydroxyalkyl groups) to meet the demands of high-end materials.

N,N' -dioil-based adipic amide is mainly applied in fields such as polymer materials and nuclear fuel reprocessing, as follows:
In the field of polymer materials 1: It can be used as a lubricant in materials such as polybutylene terephthalate films. When used as the base material layer for battery packaging materials, it helps to endow the packaging materials with excellent formability. It can also be added as a crystallization nucleating agent to aliphatic polyester sheets and other materials to improve the crystallization performance of the materials, etc.
In the field of nuclear fuel reprocessing: Liquid-liquid extraction is an important separation method in nuclear fuel reprocessing technology. N, N-dialkyl fatty amides have attracted attention due to their harmless degradation products and the ability to reduce the volume of secondary waste through incineration. As one of them,N,N' -dioil-based hexanediamide has the potential to be applied in this field as an extractant or related additive, but the current related research and application may still be in the development stage.
Other field 6: N, N-dialkylamide substances can be used to prepare oil collectors for treating oil spill pollution on water surfaces. As a similar substance,N,N' -dioil-based hexanediamide may also have similar applications in theory. It can form an oil collection film on the water surface, reduce the surface tension of water, and cause the oil film to contract, facilitating the recovery of oil spills.
