Dioctyl Adipate (DOA) Plasticizer

Product Overview

Dioctyl Adipate (DOA) from ‌WSD CHEMICAL‌ is a premier low-temperature plasticizer renowned for its exceptional efficiency in imparting outstanding flexibility and cold resistance to polymer compounds. As a linear aliphatic ester, it is the preferred choice for applications that must remain pliable and crack-resistant in extremely cold environments. ‌WSD CHEMICAL's‌ DOA offers superior performance in PVC, synthetic rubbers, and other polymers where enduring flexibility at sub-zero temperatures is critical.

Key Specifications

Core Features & Benefits

Superior Low-Temperature Flexibility‌: The primary advantage of ‌WSD CHEMICAL's‌ DOA is its unparalleled ability to maintain polymer flexibility at very low temperatures. It significantly lowers the glass transition temperature (Tg) of compounds, preventing embrittlement and cracking in cold climates.

High Plasticizing Efficiency & Fast Fusion‌: Exhibits excellent compatibility and high plasticizing efficiency with PVC, nitrile rubber (NBR), and other polar polymers. It promotes rapid gelation and fusion during processing, improving production efficiency.

Good UV & Heat Stability‌: Offers good resistance to ultraviolet light and reasonable heat stability, contributing to the longevity of outdoor products when used in appropriate formulations.

Low Volatility & Good Hand Feel‌: Has relatively low volatility, which helps maintain flexibility over time. It also imparts a soft, non-greasy feel to finished products, enhancing user experience.

FDA-Compliant for Food Contact‌: ‌WSD CHEMICAL's‌ DOA grades comply with U.S. FDA regulations (21 CFR 175.105, 177.2600, etc.) for use in food packaging and handling applications, making it suitable for a wide range of sensitive uses.

Primary Applications

· ‌Low-Temperature PVC Products‌: Refrigerator gaskets, freezer wraps, cold-weather tarpaulins, outdoor equipment covers, and automotive interior parts exposed to cold.

· ‌Synthetic Leather & Coated Fabrics‌: Where maintaining softness and flexibility in cold conditions is essential.

· ‌Food Packaging & Films‌: Used in cling films, food wraps, and other packaging materials requiring FDA compliance and cold flexibility.

· ‌Nitrile Rubber (NBR) Compounds‌: A key plasticizer for NBR, improving its low-temperature properties for seals, gaskets, and hoses.

· ‌Adhesives & Sealants‌: To enhance low-temperature performance and flexibility.

Recommended Usage

· ‌Typical Loading in PVC‌: ‌20 - 50 phr‌ (parts per hundred resin), depending on the required degree of flexibility and low-temperature performance.

· ‌Synergistic Blending‌: Often used in combination with primary plasticizers like DOP or DOTP (available from ‌WSD CHEMICAL‌) to balance cost, performance, and low-temperature properties. Our technical team can assist with optimal blend ratios.

Packaging & Storage

· ‌Packaging‌: Available in 200 kg drums, 1000 kg IBC totes, and bulk tanker loads. ‌WSD CHEMICAL‌ provides secure and traceable packaging.

· ‌Storage‌: Store in a cool, dry, well-ventilated area away from heat sources and open flames. Keep containers tightly closed to prevent moisture absorption.

· ‌Shelf Life‌: 24 months from the date of manufacture when stored under recommended conditions.

Safety & Handling

· ‌General Handling‌: Use with adequate ventilation. Avoid prolonged skin contact. Standard personal protective equipment (PPE) such as gloves and safety glasses is recommended.

· ‌Regulatory‌: Compliant with relevant regulations for its intended uses (e.g., FDA, REACH). Please consult the Safety Data Sheet (SDS) provided by ‌WSD CHEMICAL‌ for detailed handling, storage, and regulatory information specific to your market.
