Neat plasticizer volatility is an important property indicating the relative permanence of plasticizers.
Jayflex™ DINP and DIDP exhibit low weight loss translating in better retained properties over time after heat aging.
Heat aging is an important test to demonstrate plasticized
PVC durability and reliability over time. The charts below demonstrate the higher retained elongation observed with DINP and DIDP based compounds, versus DOP and the lowest neat plasticizer weight loss compared to most commercial plasticizers.
Volatile losses
The rate of volatile loss of a plasticizer from PVC is controlled by diffusion to and evaporation from the surface. Rates of plasticizer losses can be anticipated from the neat plasticizer weight loss. Jayflex
™ DINP and DIDP offer a high level of permanency compared to terephthalates or cyclohexanoates. Alternative plasticizers such as adipates, di-benzoates or citrates are substancially more volatile than Jayflex
™ DINP and DIDP.
High permanency and low volatile losses
Resistance to volatile loss from the end product under service conditions constitutes a key factor for plasticizer selection. For most flexible applications, in-service plasticizer evaporation is the essential parameter that drives finished product durability. Jayflex™ DINP and DIDP plasticizers exhibit the lowest level of volatile losses and therefore the highest level of permanency.

Better retained properties after aging.
Maximum weight loss or change of mechanical properties (stress at break, elongation at break) before and after aging determines the suitability of compounds for wire and cable. Jayflex
™ DINP and DIDP plasticizers help compounds reach the highest levels of retained properties after aging.

Improved flexible PVC processing
A low solution temperature indicates that dry blends can form at a relatively low temperature, will occur faster at a set temperature or that plastisols will gel and fuse at a lower temperature. It also indicates that the plasticizer is tolerant of the use of secondary plasticizers.
Jayflex™ DINP and DIDP plasticizers help to better achieve the key stages of flexible PVC processing, such as dryblending, full fusion and development of optimum mechanical properties.

Good plastisol pre-gelation and fusion
When processing plastisols, the gelling energy is worked only by heat transfer. The higher the plasticizer solution temperature, the higher the processing temperature or the longer time needed to achieve plastisol gelation. The rate of plastisol viscosity increases with the temperature is an indication of the solvency power of the plasticizer and its ease of processing. Jayflex™ DINP is faster gelling than most alternative plasticizers, and plastisol gelation can be further enhanced with the addition of the recently commercialized Jayflex™ MB10 plasticizer.

Good extraction resistance
Jayflex™ DINP and DIDP plasticizers exhibit similar resistance to extraction versus alternatives but due to lower volatility will show lower losses over time, and longer product life.

Not all plasticizers are meeting car interior fogging requirements
Fogging is the tendency of car interior materials to produce a light scattering film on a glass surface. Evaporation of plasticizers from car interior components can contribute to fogging but are not the sole contributor to fogging.
Typical automotive requirements call for neat plasticiser fogging condensates below 1 mg Typical automotive requirements call for neat plasticizer fogging condensates (16 h/100°C) - DIN 75201 B) below 1 mg or retained gloss above 75% (16 h/100°C) - DIN 75201 A).
Only Jayflex
™ DIDP, DIUP and DTDP plasticizer meet this requirement.
