Simulation for the migration of nitrate ester plasticizers in different
The diffusion coefficients of the nitrate ester plasticizers in various liners were in the order of PEG/N-100-NG>HTPB/IPDI ... The HPLC investigation of stabilizer has shown good stability of the
Current Status of Plasticizer Research | SpringerLink
Benzoate-based plasticizers made from C 8 –C 12 alcohols have the following exceptional properties: (1) comprehensive plasticization performance with small side effects; (2) good compatibility with most synthetic resins and rubbers; (3) low release leading to high stability; (4) high resistance to heat and weather, low volatility, good low-temperature flexibility, low extraction, no tendency
Synthesis of novel plasticizer ester end-capped oligomeric lactic acid
According to the results of tensile tests, the elongation at break of PVC plasticized by 50 phr EOLs reached 725.5%, indicating its superior mechanical properties. The result of TGA showed that the thermal stability of PVC plasticized by EOLs was as comparable as that of PVC plasticized by DOTP or ATBC.
Plasticizers: Types, Uses, Classification, Selection & Regulation
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. They are made from aliphatic dibasic acids such as adipic acid and alcohols.
Preparation and Performance of Bio-Based Polyol Ester
The improved thermal stability of PVC/50phr CPE is may be attributed to the thermally stable chemical groups: ester groups. Hence, substituting DEHP with CPE can improve the thermal stability of plasticized PVC. The commercial plasticizer such as DEHP shows only one Tg in plasticized PVC systems, which indicated a excellent corruptibility [35, 36].
- 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.
- What is Dibasic ester?
- Dibasic ester can be the substitute of isophorone,cyclohexanonel, ether type of solvent and so on. Environment-friendly high boiling solvent MDBE (Mixed Dibasic Esters),also named DBE,it is a mixture of three dibasic esters. Dibasic ester main ingredient is Dimethyl Succinate,Dimethyl Glutarate,Dimethyl Adipate.
- 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.
