ISP expands Flexidone range with new plasticizer series
International Specialty Products Inc (ISP) has launched Flexidone FE, a new series of PVC plasticizers containing alkyl pyrrolidone technology. The new products can serve as either primary plasticizers or co-plasticizers that may be formulated in conjunction with other plasticizer technologies to achieve greater cost savings, while maintaining or improving performance, the company says

New Plasticizer Chemistry for PVC Excels in Cold & Heat
In plastisols or dryblends, replacing 15% to 30% of other plasticizers with Flexidone will reduce mix times and temperatures and also provide significant improvements in transparency of clear vinyls, Kaytan says. Flexidone has been used for more than two years in extruded PVC pencil erasers.

- What is flexidone plasticizer?
- Therefore the Flexidone family of plasticizers represents breakthrough technology in “cold flex” performance of plastics. Depending on the application, it can offer a great deal more. Flexidone plasticizers expand the options in PVC formulation, manufacturing and end-product design.
- What is the difference between DINP and flexidone 300?
- These show e.g. a hardness of 80 Shore A can be achieved with 33 parts of Flexidone 300 (C-12 Pyrrolidone) compared to 60 parts of DINP. In this example the same flexibility can be reached with 45 % less plasticizer. Fig. 3. The dependence of hardness on plasticizer content (parts per100 parts of PVC) tor DINP and Flexidone 300.
- Are flexidone plastisols more efficient than standard plasticizers?
- Gelling curves of PVC plastisols (50 phr plasticizer) with various mixtures of Vestinol 9 and Flexidone100, 300, DBP and BBP. 5. Conclusion It could be shown, that Flexidone’s are very efficient PVC plasticizers. They are up to 50% more efficient than standard plasticizer.
- Can flexidone be used as a substitute for DINP/CP?
- As a substitute for the DINP/CP-system (with Shore A 53) we could offer a Flexidone/ESO system with 80 phr ESO and 20 phr Flexidone 300 showing the same softness (Shore A 50) and lower processing temperature even with a lower plasticizer content and an increased amount of CaCO3 (see Table 1). Table 1.
- Why is flexidone 100 a good surfactant?
- Flexidone 100 is amongst the surfactants with the highest dynamic wetting properties. This means that a partial substitution is sufficient in order to reduce foaming to a minimum and thereby significantly shorten degassing cycles. During the processing of PVC plastisols the gelling temperature is of particular interest.
- Can flexidone replace fast-fusing plasticizers in DINP?
- In plastisol applications DBP and BBP are widely used as fast-fusing plasticizers in DINP. As figure 18 proves, Flexidone 100 and 300 can easily replace fast-fusers with unfavourable ESH profile.
