Natural-based plasticizers and biopolymer films: A review
Phthalic acid esters found applications as plasticizers for the first time in 1920 and continue to be the largest class of plasticizers in the 21st century [4]. Di (2-ethylhexyl) phthalate (DEHP), also known as dioctyl phthalate (DOP), was introduced in 1930 and has been the most widely used plasticizer since the 1930s.
Flexricin Castor Oil Esters Series - Vertellus
Flexricin Esters are low volatility plasticizers with excellent electrical insulating properties, superior lubricity and heat stability. Plasticizer for Nitrocellulose & Epoxies For nitrocellulose, epoxies, and other materials, Flexricin Esters improve cold-crack resistance and impart excellent plate release. Features Phthalate-free
Bioplasticizer - an overview | ScienceDirect Topics
In the mid-1970s, Hercules Chemical Company introduced two polyol ester plasticizers, Hercoflex 600 and Hercoflex 707. These plasticizers were prepared by the esterification of pentaerythritol and dipentaerythritol with a mixture of short-chain acids, predominately C6 acid.
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.

- What is an ester plasticizer?
- An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one.
- What is a general performance ester plasticizer?
- Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length. Ester plasticizers are commonly used only for their as-molded, low-temperature contribution.
- How to choose a high-performance ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer. 1.
- Can polymeric esters enhance a high-performance elastomer?
- One example of how polymeric esters can enhance a high-performance elastomer is depicted in Figure 3. High-saturated nitrile is used in many high-heat applications. The use of 8-10 trimellitate is well documented as the plasticizer of choice for HNBR.
- Are plasticizers suitable for elastomers and high-temperature polymers?
- Plasticizers commonly used for the traditional and the high-temperature polymers are extractable, incompatible or too volatile. This paper provides information on plasticizers that are designed for traditional elastomers and high-performance polymers.
- Which polymeric plasticizer is best for acrylics?
- Polymeric plasticizers that are efficient in lowering hardness, provide good low-temperature properties and have low volatility in both post-cure and heat aging are ideal candidates for acrylics. Two polymeric plasticizers that meet these requirements are polyester adipates with a molecular weight of 1000.
