DOP plasticizer Himik Plast

40-50% solution of thermoplastic polyurethane in dioctyl phthalate. It is available as a clear liquid from light yellow to light brown hues with a dynamic viscosity at 50 ° C. 0,25-20 Пас. Designed for use as an additive in polyvinyl chloride, nitrocellulose and epoxy compositions instead of dioctyl phthalate (DOP) or mixed with it. Partial or complete replacement of low molecular weight DOP with Himik Plast polyurethane modifier reduces the migration activity of the plasticizer, increases frost and wear resistance of products. The field of application is the production of cable plastic compounds, artificial leather, rubber products, polymer building materials, linoleum, packing film, fiberglass pipes. The company "Iskorzh" (Neftekamsk) has optimized the serial PVC composition VIC-TR (TU 17 RSFSR 5790484-059-90), used to produce artificial leather on the top of the shoe, by replacing part of the DOP with Himik Plast. In addition to improving the resistance of the skin to the effects of aggressive media such as oils and brine, the main advantage of it is an increase in wear resistance. Resistance to multiple bending is more than 300 kilo-cycles, and cold-resistance to bending at minus 10 ° C is more than 60 kilocycles. Replacement of dioctyl phthalate with a polyurethane modifier in the compositions of epoxy compositions used for the manufacture of fiberglass and products made it possible to significantly improve their elasticity, frost resistance, heat resistance, and reduce abrasive wear without changing the production technology. The greatest effect of the use of the polyurethane modifier in the composition of epoxy compounds for the manufacture of GRP pipes and tanks is to increase the fracture toughness of the finished containers and, as a result, increase the maximum working pressure that the finished products can withstand. Tests of natural specimens of GRP pipes (TU 2296-003-12015366-93) with a diameter of 110 mm using polyurethane plasticizer in the composition of epoxy impregnating compound in an amount of 20% showed that the control sample of the pipe lost its tightness at a pressure of 30 kgf / cm2, while the pipe on the composition with the modified binder retained its tightness up to the limit of the capacity of the test bench - 80 kgf / cm2. Properties of the final product Fiberglass Pipes - Increase strength and tightness by 1.5 times (from 4, MPa to 6 MPa) - Pressure inside the pipe increases 3 times - Frost resistance increases by 2 times - Chem. Persistence increases by 3 times PVC Fabrics - an increase in the relative elongation (elasticity) by a factor of 2 with the preservation of strength properties - Frost resistance increases by 2 times - Resistance to repeated bending is more than 300 kilo-cycles, and cold-bending resistance at minus 10 ° C is more than 60 kilocycles. - Resistant to aggressive environments Glass-plastic boat - an increase in the relative elongation (elasticity) by a factor of 2 with the preservation of strength properties - Increase strength and tightness by 1.5 times (from 4, MPa to 6 MPa) - Frost resistance increases by 2 times - Resistant to aggressive environments
