PENTAERYTHRITYL STEARATE - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| introduction | pentaerythritol stearate (PETS) is usually a white hard high melting point wax, soluble in ethanol, benzene and other solvents. TGA: pyrolysis gravimetric analysis results show that PETS still has no obvious weight loss at 350 ℃. At 375 ℃, the weight loss is about 2.5%. It only starts to decompose at 400 ℃ (weight loss is about 7%). |
| characteristics | pentaerythritol stearate has the following characteristics: 1. mold release-effectively reduce melt viscosity, less dosage and good mold release effect; 2. High gloss-extremely low turbidity tendency, effectively enhancing the transmittance of transparent plastics to improve the appearance of finished products; 3. High temperature resistance-good structural thermal stability and low volatility at high temperature. |
| Application | Pentaerythritol stearate has good thermal stability and low volatility at high temperatures, good mold release and flow properties, and partially crystallized plastics It has an excellent nucleation effect and can be used in transparent products. Due to its outstanding thermal stability, pentaerythritol stearate can be used in the processing of such systems without worrying about degradation, and it can significantly improve transparency and surface finish. During extrusion and molding, pentaerythritol stearate is an effective lubricant for many polymers and can be used as thermoplastic engineering plastics. It can also be used as an external lubricant for PC, hard PVC and other polymer systems. |
| Use | Used as raw material for rubber additive production |
