The plasticizer market: An assessment of traditional
[6, 7] Phthalate-based compounds are the most commonly used plasticizers for PVC, accounting for approximately two-thirds of PVC plasticizers produced in 2018. [8] Of these, di (2-ethylhexyl
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto
The plasticizer market: an assessment of traditional
PVC-based medical plastics have received the most attention partly because medical uses constitute 10% of the phthalate plasticizer market [23]. The PVC used in IV and blood storage bags typically contain 30–40 wt% DEHP and medical tubing such as dialysis tubing may contain as much as 80 wt% DEHP [24]. This DEHP has been shown to leach out of
Recent Attempts in the Design of Efficient PVC
Abstract and Figures. This paper reviews the current trends in replacing commonly used plasticizers in poly (vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to
Recent Attempts in the Design of Efficient PVC Plasticizers
Chemical and physical properties of PVC formulations containing a wide range of plasticizers have been compared, allowing observance of the improvements in polymer performance in comparison to PVC plasticized with conventionally applied bis(2-ethylhexyl) phthalate, di-n-octyl phthalate, bis(2-ethylhexyl) terephthalate and di-n-octyl terephthalate.
- 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.
- 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 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. Fig. 18. Gelling curves of PVC plastisols (50 phr plasticizer) with various mixtures of Vestinol 9 and Flexidone100, 300, DBP and BBP. 5. Conclusion
- 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 flexidones cold flexible?
- Cold Flexibility with the Flexidones was checked by the Folding test DIN EN 495-5. Further trials in filled systems showed that Flexidones are highly compatible with e.g. calcium carbonate and allow very high filler loads with outstanding mechanical properties.
- Are flexidone mixtures better than other phthalate-free systems?
- As a function of the ratio of mixture indentation hardness, tensile properties and gelling properties (plastisol) have been evaluated. Compared to common systems, these new Flexidone mixtures surpass the performance characteristics and are superior to most of the phthalate and phthalate free systems.
