Plasticizers | ExxonMobil Product Solutions
Jayflex DTDP plasticizer is the highest-molecular-weight phthalate plasticizer, providing greater performance at high temperatures. It is the preferred plasticizer for automotive cable applications and THHN/NMB electrical wire insulation. Learn more Linear plasticizers
Plasticiser loss from plastic or rubber products through
Plasticisers are commonly added to polymers to lower their glass transition temperature and increase their processability, mechanical flexibility, ductility and toughness. 1,2,3,4,5 They represent
Phthalates: European regulation, chemistry, pharmacokinetic
Low molecular weight phthalates: dibutyl phthalate (DBP), benzyl-butyl phthalate (BBP), di-2-ethyl-hexyl phthalate (DEHP) are classified as very dangerous in REACH. Phthalates are widely used as film-forming agents, solvents and denaturants, but especially as plasticizer substances which, when added to the plastic, make it more flexible and

High Molecular Weight Phthalates Plasticizers
The bulk of useful plasticizers are phthalates, in particular ortho-phthalates. They can be divided into low and high molecular weight. Low molecular weight phthalates can be further divided into ortho and tere-phthalates. High molecular weight ortho-phthalates improve your processing and offer a high degree of permanency. There are no high
- What are phthalate plasticizers?
- From a chemical point of view, phthalate plasticizers come from an esterification reaction between phthalic anhydride and an alcohol with specific characteristics. Phthalates are the most used molecules in many sectors of industrial production.
- What type of plasticizer is used in PVC?
- The specific type of plasticizer that is of concern to this report is the phthalate plasticizer. Phthalate plasticizers are the most commonly used plasticizers in PVC. The PVC polymer chains are attracted to one another, and therefore from a very rigid structure.
- What is the market share of plasticizer phthalates?
- The substitution of the formerly dominant plasticizer DEHP (EU market share 1996: 51%; 2015: 10% [36, 58] has led to a fundamental shift in the market since the 1990s toward HMW phthalates , with a simultaneous steady growth in demand for soft PVC [59, 74].
- Are phthalate plasticizers dangerous?
- Phthalate plasticizers have been found to be a health concern when found in direct contact with bodily fluids. Studies performed on laboratory animals have shown that there is direct evidence that certain phthalate plasticizers have a carcinogenic effect in vivo.
- What are the two types of plasticizers?
- Two classes of plasticizer exist: primary and secondary. Primary plasticizers are, in a way, “true plasticizers.” These are the chemicals that interact with the polymer to increase its flexibility. Secondary plasticizers, on the other hand, act not on the polymer but the primary plasticizer, increasing its effectiveness (10).
- Are HMW phthalates a good plasticizer?
- However, HMW phthalates already constituted a comparatively strong proportion in the mid-2000s. In general, plasticizers with low volatility and migration rate are more suitable for stressed outdoor applications with respect to hydrolysis, leaching and microbial degradation [72, 116].
