Plasticizers: Types, Uses, Classification, Selection & Regulation
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 Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates.
Selecting Plasticizers for Adhesives and Sealants
Plasticizers that are used in adhesive and sealant formulations are generally chosen on the basis of the following criteria: Compatibility with a given polymer or set of component ingredients. Compounding characteristics. Effect of plasticizer on the rheological properties of the polymer.
TegMeR | Hallstar Industrial
TEGMER 809 is a PEG 400 ester plasticizer for high polarity elastomers and plastics. This plasticizer offers good resistance to water extraction and good low temperature properties. →
Eastman Plasticizer A to Z List - Eastman Chemical Company
Eastman 168 Renew 20 non-phthalate plasticizer performs as good as or better than most ortho-phthalate plasticizers. In general-purpose plasticizer applications, it offers good performance properties, excellent low-temperature flexibility, resistance to extraction by soapy water, and excellent nonmigration properties.
Selected Fatty Acids Esters as Potential PHB-V
However, it seems that this amount of free fatty acids is still relatively low and shouldn’t affect the efficiency of this ester as a plasticizer. Ester 1 similarly to ester 4 is characterized by higher than other esters iodine value, respectively 77.6 g I 2 /100 g and 75.7 g I 2 /100 g, cause both of them were obtained by oleic acid
- 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.
- Which plasticizer is best for acrylic elastomers?
- Table V highlights data from this study conducted by DuPont Dow Elastomers L.L.C. ®. DBEEEG, a high molecular weight glycol ether ester monomeric plasticizer, is commonly recommended for acrylic elastomers. In this study, A-1000A and A-1000B show they are equal or better than DBEEEG at softening efficiency and original low temperature.
- Which plasticizers are used in combination with specialty monomeric esters?
- Flame-retardant plasticizers, phosphate esters and chlorinated paraffins are often combined in usage with flame-retardant plasticizers frequently used in combination with specialty monomeric esters. Both materials are inefficient plasticizers, thus explaining their combinations with specialty monomerics.
- Do fluorocarbon elastomers accept ester plasticizers?
- Fluorocarbon elastomers will accept a relatively wide range of ester plasticizers, but here, with both the high temperature post cure and application temperatures ranging to 232°C, they find use only at very low levels for processing. The selection of an ester plasticizer can often be confusing because of the large choice available.
