Description
Specialty Plasticizers are essential additives used to modify the physical properties of polymers, primarily enhancing flexibility, workability, and processability. A&D Polymers provides a specialized portfolio of plasticizers including Dioctyl Phthalate (DOP), Dioctyl Adipate (DOA), and Trioctyl Trimellitate (TOTM), each engineered for targeted applications in PVC, rubber, and high-performance plastics.
As part of our commitment to technical excellence and customer-driven solutions, these plasticizers are selected for their ability to improve product softness, durability, and thermal behavior in both standard and demanding industrial applications.
Functional Properties of Specialty Plasticizers
DOP (Dioctyl Phthalate)
DOP is the most widely used phthalate plasticizer for PVC applications. It provides excellent compatibility, low volatility, and cost-efficiency, making it a reliable choice in flexible PVC formulations.
Key Functions:
Enhances flexibility in soft PVC
Maintains consistent performance over a wide temperature range
Provides balanced plasticizing efficiency and permanence
DOA (Dioctyl Adipate)
DOA is an aliphatic ester known for its low-temperature flexibility and UV resistance. It’s commonly used in outdoor applications and plastic films that demand long-term clarity and softness.
Key Functions:
Offers excellent low-temperature performance
High resistance to cold and UV degradation
Superior compatibility with light-sensitive compounds
TOTM (Trioctyl Trimellitate)
TOTM is a high-performance plasticizer for high-temperature and long-term applications. It provides superior extraction resistance and is highly suited for medical, automotive, and electrical insulation uses.
Key Functions:
Outstanding thermal stability and permanence
Excellent resistance to chemical migration
High retention of properties in high-heat environments
Applications of Specialty Plasticizers
DOP Applications
Flexible PVC cables and wires
Synthetic leather
Flooring and wall coverings
Footwear soles
Automotive interiors
DOA Applications
Food-grade cling films and packaging
Outdoor vinyl products
Flexible tubing and hoses
Waterproof clothing
Automotive seals
TOTM Applications
Medical-grade vinyl (tubing, blood bags)
Automotive wire insulation
High-temp electrical cables
Gaskets and seals
Aerospace and defense-grade materials
Key Benefits and Performance Enhancements of Specialty Plasticizers
Enhanced Flexibility: All three plasticizers improve the plasticity of polymers, allowing for better shaping and molding during processing.
Improved Processability: Optimize melt flow and reduce processing temperature requirements.
Thermal & UV Stability: DOA and TOTM significantly extend product lifespan in outdoor and high-heat environments.
Migration Resistance: TOTM exhibits superior resistance to leaching, ideal for critical applications like healthcare and wiring.
Cost-Effectiveness: DOP remains a preferred economic solution for general-purpose flexible PVC formulations.
Regulatory Compliance: Select grades of DOA and TOTM meet regulatory requirements for food contact and medical use, depending on formulation.
