Definitions

  • DINT Diisononyl terephthalate
  • the invention relates to the use of diisononyl terephthalate (DINT) as a plasticizer to increase the low-temperature flexibilization and / or to increase the permanence in polymer compositions for thermoplastic applications.
  • DINT diisononyl terephthalate
  • Polyvinyl chloride is one of the most economically important polymers and is used both as rigid PVC as well as soft PVC in a variety of applications. Important areas of application are, for example, profiles, floor coverings, wallpaper and artificial leather.
  • plasticizers are added to the PVC. These conventional plasticizers include, for example, phthalic acid esters such as di-2-ethylhexyl phthalate (DEHP), diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP).
  • Cyclohexanedicarboxylic esters such as, for example, diisononylcyclohexanecarboxylic acid esters (DINCH), have recently become known as further plasticizers.
  • DINCH diisononylcyclohexanecarboxylic acid esters
  • DEHT di-2-ethylhexyl terephthalate
  • An essential decision criterion for the selection of a plasticizer is its permanence in the corresponding end use, eg. B. body or article in the corresponding plastic form.
  • the permanence of the plasticizer is determined primarily by its tendency to migrate and the volatility of the plasticizer in or out of the corresponding polymer matrix. The lowest possible volatility is generally desirable, so that the proportion of plasticizer emitted by evaporation from the plastic article remains as low as possible. This has the consequence for the material that the mechanical properties remain constant, especially when the material is subjected to an increased thermal load (ie a temperature of use which is higher than room temperature).
  • the volatility can be determined on the one hand from the boiling point of the plasticizer itself, but also by determining the loss in mass of a PVC article produced with this plasticizer after storage at elevated temperature.
  • a PVC article produced with this plasticizer after storage at elevated temperature For use as insulating or sheath material for electric cables, moldings containing soft PVC are used.
  • high demands are placed on the corresponding formulations in terms of volatility, mechanical and electrical properties and, for example, also thermal stability. These requirements are in most cases covered by national or international standards such as DIN EN 50363-4-1 (VDE 0207-363- 4-1), DIN EN 50363-3 (VDE 0207-363-3) or, for example, by UL standards (Underwriters Laboratories).
  • plasticizers or part of a plasticizer composition in plastics or plastic components, among other things because these products have a low glass transition temperature and they are liquid in a certain temperature interval.
  • a plastisol which is easy to process can be obtained hereby.
  • plastisols are only flowable mixtures of plasticizers and polymers (and possibly other additives), they are not yet "gelled” and therefore not a plasticized plastic, therefore no statement can be made about the suitability for certain applications.
  • the volatility of a plasticizer within a homologous series decreases with increasing molecular weight, ie, that at the same time its general applicability at elevated temperatures of use increases in the mt.
  • the choice of different plasticizers may be necessary.
  • DEHT di-ethylhexyl terephthalate
  • DINP di-isononylated as plasticizers.
  • This plastic articles can be provided which have excellent material properties (including a significantly lower mass loss at elevated service temperature), and at the same time are free from ophthal-phthalates, which is used to prepare the di-isononyl terephthalate an alcohol, which is available industrially in large quantities.
  • Isononyl alcohol esters are open to applications previously reserved for the more expensive esters of C10 alcohols.
  • DINT diisononyl terephthalate
  • Another advantage is that the high permanence of the terephthalic acid esters according to the invention, even at elevated temperatures, the plasticizer load of indoor air and house dust can be significantly reduced. This is of particular importance for floor coverings and PVC membranes (eg roof sheeting and roofing membranes).
  • the present invention is therefore the use of diisononyl terephthalate (DINT) as a plasticizer to increase the Cryogenic flexibilization and / or to increase the permanence in polymer compositions for thermoplastic applications.
  • DINT diisononyl terephthalate
  • Thermoplastic applications are understood to be all applications in which the molding is carried out at the processing temperature (from 1 30 to 280 ° C., preferably from 1 50 to 250 ° C.).
  • thermoplastic processing methods are calendering, extrusion, injection molding, slush molding, etc. In each case either a powder mixture or a granulate is brought into the desired shape by processing in the molds. At the processing temperature, the so-called plasticizing process occurs, in which the molten primary particles are finely dispersed and, after cooling, a substantially homogeneous mass is produced.
  • diisononyl terephthalate is used as a plasticizer in flooring compositions, profiles, roofing membranes or roofing membranes, cable insulation and cable sheathing.
  • DINT can be advantageously used in compositions for hoses and containers, in particular for storage and transport of liquids such as water, blood, infusion solutions but also drinks. Examples of corresponding formulations for medical and / or container medicine are listed in D E 202010004386 U1.
  • the increase in the low-temperature flexibilization is also advantageous here, since numerous nutritional solutions or stored blood are stored for a long time at low temperature, without the containers may become brittle.
  • numerous applications such as for example pumps, swimming pool foils and outdoor profiles, are used where they are exposed to high temperatures in summer and therefore a high low-temperature flexibilization but also low volatility are of advantage.
