Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
Dioctyl adipate
Dioctyl adipate ( DOA) is an organic compound with the formula (CH 2 CH 2 CO 2 C 8 H 17) 2. It is a colorless oily liquid. As well as related diesters derived from 2-ethylhexanol, decanol, isodecanol, etc., it is used as a plasticizer. [2] [3] DEHA is sometimes incorrectly called dioctyl adipate. Toxicity [ edit]
Bis(2-ethylhexyl) terephthalate
It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl. This colorless viscous liquid is used for softening PVC plastics and is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure.
Eastman DOA Plasticizer - Eastman
Eastman DOA Plasticizer. Light colored, oily liquid dioctyl adipate. Used as a plasticizer for PVC. Can be blended with other plasticizers such as DOP and DOTP. Features flexibility at low temperatures, good electrical properties, good resistance to weathering, and good stability to heat. Used to produce clear films for food packaging
Energetics and Compatibility of Plasticizers in Composite
But the selection of a plasticizer calls for a hard compromise of many factors such as energetics, compatibility, processability, availalility and cost potential. This was achieved through experimentation in the propellant system. The compatibility of 1 I different plasticizers such as dioctyl adipate (DOA)
- What is Dioctyl adipate?
- DOA, dioctyl adipate is a primary plasticizer. It is the most important in the adipate group, it offers a high efficiency, better flexibility properties at low temperatures and resistance to the loss of color by exposure to heat and ultraviolet light.
- What is DOTP plasticizer?
- DOTP is a primary non-phthalic plasticizer resulting from the esterification of 2 Ethyl Hexanol with Terephthalic Acid. It offers good mechanical properties and permanence. It provides excellent flexibility, good dielectric properties and similar volatility to DOP. It is suitable for cable cover, vinyl floors and other flexible applications.
- Can DOA be used in food packaging materials?
- Only slight irritation to skin and eyes, can be used in food packaging materials (such as cling film). DOA can improve the light and heat resistance of the products and reduce the degradation caused by UV rays or high temperature, which is suitable for outdoor films and coated fabrics.
- Why is DOA a good material?
- DOA maintains the flexibility and ductility of the material at low temperatures, significantly lowering the glass transition temperature of the polymer and making it suitable for plastics used in cold environments, such as frozen food packaging film and outdoor plumbing .
- What are the advantages of DOA lubrication?
- DOA can improve the light and heat resistance of the products and reduce the degradation caused by UV rays or high temperature, which is suitable for outdoor films and coated fabrics. Artificial leather and plates: Improvement of low-temperature flexibility, enhancement of surface lubrication and water resistance.
- What types of materials are used by doa?
- Coated fabrics: such as synthetic leather and textiles, to improve oil resistance and durability. Adhesives and inks: to improve flexibility and adhesion. DOA complies with a number of international safety standards (e.g. REACH, TSCA) and is used in the electrical and electronics industry for the production of environmentally friendly materials.
