| Item | Units | RH-1500C | Remark |
| IntrinsicViscosity | dL/g | 0.73±0.015 | Indicates the size of polymer molecules and its corresponding mechanical performance. The Viscosity is higher, the mechanical performance is better. |
| Melting Temp | °C | 191±2 | The product is non-crystalline and has no defined melting point. The melting point is measured by a microscope to obtain themelting temperature. |
| Carboxyl Group | mol/ton | ≤35 | High terminal carboxyl content will reduce the thermal stability of the product. |
| Color Value(b-value) | / | 1±2 | b:Yellow color index; higher values indicate more yellow. |
| Color Value(L-value) | / | ≥60 | L: Lightness value. |
| Di-ethylene Glycol | % | ≤1 | Side reactions with Etherification may degrade material durabili- ty and thermal properties. |
| Moisture content | % | ≤0.4 | Processing can cause polymer degradation due to moisture. |
| Ash Content | % | ≤0.08 | Ash is used to characterize the content of impurities in polyes- ter, which comes from metal oxides decomposed by catalysts, raw materials and mechanical impurities generated during the production process. |
| Density | g/cm³ | 1.27 | |
| Melt Flow Index | g/10min | 10±2 | Melt flow rate at 210°C with a 2.16kg weight. |
Note:
1. The intrinsic viscosity is a phenol/tetrachloroethane mixed solvent of 3:2, tested at 25°C
2. This polyester is an amorphous polyester material, and there is no melting peak in the DSC test; therefore, the melting point is tested by microscopy, and the mid-melting temperature is taken.
3. This polyester can be widely used in 3D printing consumables, polyester plates, sheets, polyester injection molding, home appliances and other fields.
