Polymers | Special Issue : Green Plasticizers for Polymers - MDPI
Several linear alkyl diol dibenzoate compounds, ranging from C3 to C6 in central diol length, were evaluated for their plasticizing effectiveness in blends with poly (vinyl chloride) (PVC). The results were compared to blends of PVC/di (2-ethylhexyl) phthalate (DEHP), the most commonly used commercial plasticizer. [...] Read more.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Phthalate esters are still the most powerful plasticizers and dominate the plasticizer market due to their great plasticizing effect and low-cost, although phthalate plasticizers can migrate to
Eastman Product List for Polymeric Plasticizers
Admex 525 is a low molecular weight, polymeric plasticizer. Admex 760 is an ultra-high molecular weight, polymeric adipate. It possesses maximum resistance to extraction, migration and volatility. Admex 770 is a medium molecular weight, polymeric adipate. It is characterized by a mild ester odor and very light color.
Paraplex | Hallstar Industrial
Paraplex A-7020 is an ester plasticizer designed for fast fusing of PVC plastisols. This product can be used to reduce fusion temperature as well as gel point in comparison to standard phthalates. PARAPLEX A-8000 PARAPLEX A-8000 is one product in a series of polymeric plasticizers that utilize the PARAPLEX APPROACH.
- What is a polymeric plasticizer?
- Polymeric polyester plasticizers may be used in higher-performance applications where superior plasticizer non-volatility and fluid chemical extraction resistance are critical. Polymeric plasticizers are produced by reacting a dibasic carboxylic acid with a glycol or a mixture of different dibasic glycols.
- 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.
- Which elastomers use polymeric esters?
- Polymeric esters are especially suited for high performance elastomers, such as nitrile, high saturated nitrile and polyacrylates. Polymeric esters also have found utility in chlorinated polyethylene, chlorosulfonated polyethylene and fluoroelastomers.
- How are polymeric plasticizers produced?
- Polymeric plasticizers are produced by reacting a dibasic carboxylic acid with a glycol or a mixture of different dibasic glycols. When the molecules are reacted, the chain propagation or building may be terminated by the use of monofunctional carboxylic acids or alcohols. Some polymeric plasticizers are also produced using no terminator.
- 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.
- 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.
