1. Plastics Industry (Core Applications)
This is the primary application area for DOA, particularly in polyvinyl chloride processing.

PVC Plasticizers:

Cold-Resistant Plasticizer: A key advantage of DOA is its ability to provide PVC products with excellent low-temperature flexibility and cold resistance. It significantly lowers the glass transition temperature of PVC plastics, preventing them from hardening and becoming brittle at low temperatures.

Primary Plasticizer: Exhibits excellent compatibility with PVC resin, making it suitable as a primary plasticizer.

Application Products:

Cold-Resistant Wire & Cable Compounds: Used for insulation and sheathing in wires for cold regions or inside refrigeration equipment.

Artificial leather (PVC leather): Particularly suited for products requiring soft hand feel and fold resistance, such as automotive interiors, furniture leather, gloves, and footwear materials.

Films and sheets: Used in agricultural films, packaging films, raincoats, tablecloths, etc., to enhance flexibility and low-temperature performance.

Flexible tubing and gaskets: Applications requiring good elasticity and sealing properties.

2.橡胶工业
As a rubber softener and plasticizer in processing natural and synthetic rubbers (e.g., styrene-butadiene rubber, neoprene). It improves processing properties (reduces mixing viscosity and energy consumption), increases compound plasticity and flexibility, while also providing some cold resistance.

3. Coatings and Adhesives Industry
涂层： As a modifier or plasticizer for polymer resins (e.g., polyurethane, acrylic resins), it enhances paint film flexibility, adhesion, and impact resistance, particularly in low-temperature environments.

粘合剂和密封剂： As non-reactive plasticizers in PVC plastisols, polyurethane sealants, etc., it regulates system viscosity and flexibility, improving application performance and final product elasticity.

4.其他特殊应用
Lubricant Additives: Serves as a base oil or additive in synthetic lubricants, delivering excellent lubricity and low-temperature flow properties.

Specialty Solvent: Employed in chemical processes requiring specific solubility characteristics.

Polymer Processing Aid: Used as a temporary plasticizer during processing of certain high-performance engineering plastics to reduce processing temperatures.
