Composition, properties of the cold flow improvers and producer’s recommendations for their use.
| Characteristics | Cold flow improver |
||
|---|---|---|---|
| A | B | C | |
| Composition | Ethylene copolymers, vinyl ether, acrylates, ethylene glycol complex | Ligroin, vinyl acetate, naphthalene, ethylbenzene | Hydrocarbons C10–C13, paraffins, aromatic hydrocarbons, cycloalkanes, naphthalene, combination of various high-molecular weight ashless chemical compounds |
| Producer’s recommendations | Using 1 mL of the additive per 1 L of fuel lowers the pour point for summer fuel to −22 °C, for winter fuel to −47 °C | Using 150 mL of the additive to 65 L of fuel lowers CFPP to −36 °C, pour point to −40 °C | Using 150 mL of the additive to 50 L of fuel lowers the pour point to −31 °C |
| Density at 20 °C, g/sm3 | 0.843 | 0.803 | 0.807 |
| Viscosity at 20 °C, mm2/s | 5.470 | 3.254 | 4.010 |
| Molecular weight, g/mol | 162.803 | 158.772 | 165.412 |
