DOP Plasticizer | Eastman
It is the most widely used all-purpose plasticizer offered by Eastman for use with polyvinyl chloride (PVC) resins. It is insoluble in water and has a viscosity of 56 cP at 25°C. Eastman DOP features good stability to heat and ultraviolet light, a broad range of compatibility, and excellent resistance to hydrolysis.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Phthalate Esters – They are produced by esterification of phthalic anhydride or phthalic acid obtained by the oxidation of orthoxylene or naphthalene. Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates
Eastman Product List for General Purpose Plasticizers
Eastman TOTM plasticizer (Tris (2-Ethylhexyl) Trimellitate) is the ideal PVC plasticizer for use in applications where low volatility is of supreme importance, such as wire and cable insulation and interior automotive. It also has properties that are required for dishwasher gaskets and photograph storage.
Plasticizer - an overview | ScienceDirect Topics
Specialist plasticisers include phosphates for fire retardancy, polymeric plasticisers (low migration) and some newer ‘non-phthalate’ plasticisers such as citrates, benzoate esters, alkyl sulphonic phenyl esters (Mesamoll), di-isononyl cyclohexane-1,2-dicarboxylate (Hexamoll DINCH) and biobased plasticisers (e.g. Grindsted Soft-n-Safe).

- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- How to choose a plasticizer?
- The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- Which plasticizers are used in flexible PVC products?
- More than 80% of plasticizers have been applied to flexible PVC products with the rest being polyvinyl acetate, vinyl chloride - vinyl acetate copolymer, cellulose acetate, and cellulose nitrate. Although the study history of plasticizing mechanism has been over 40 years, but so far there is still no systematic theory.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature.
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
