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. Indústria da borracha
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
Revestimentos: 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.

Adesivos e selantes: As non-reactive plasticizers in PVC plastisols, polyurethane sealants, etc., it regulates system viscosity and flexibility, improving application performance and final product elasticity.

4. Outros aplicativos especiais
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.
