Chemical Properties:

  1. white beads
  2. PRACT light yellow viscous oily liquid. It is soluble in water and general organic solvents.


  1. Glycolube(R) P (Pentaerythrityl tetrastearate) is an effective lubricant for many polymer compounds in both extrusion and molding processes. It is recommended for use as a mold release agent in polycarbonate, thermoplastic polyesters and other engineering thermoplastics.
  2. PRACT is a white hard high melting point wax, soluble in solvents such as ethanol and benzene. Thermogravimetric TGA: Thermogravimetric analysis results show that PETSChemicalbook still has no significant weight loss at 350°C; at 375°C, the weight loss is about 2.5%; at 400°C, it begins to decompose (weight loss is about 7%).
  3. PRACT has the following characteristics:
    1. Releasability—effectively reduce melt viscosity, less dosage and better demoulding effect;
    2. High gloss—very low turbidity tendency, effectively enhancing the transmittance of transparent plastic to improve the appearance of the finished product;
    3. High temperature resistance—good structural thermal stability and low volatility at high temperature.
  4. PRACT is used as a raw material for the production of rubber additives.

About Us

  1. The production base is located in Zhangqiu chemical industry park and Tai’an high-tech chemical industry park. laboratory and workshop in strict accordance with the GMP standard and the product fit national ISO9001 and ISO2000 standards.
  2. “Zhishang” products are exported to Europe, North and South America, the Middle East, Asia Pacific and Africa area, so as to establish a long-term and stable cooperation relationship with customer in the world.
  3. PRACT has good thermal stability and low volatility at high temperatures, good demolding and flow properties, and has excellent nucleation effects on partially crystalline plastics. It can be used for transparent products. Due to its outstanding thermal stability, pentaerythritol stearate can be used in the processing of such systems without worrying about the degradation of Chemicalbook, and it can significantly improve transparency and surface finish. In the process of extrusion and molding, pentaerythritol stearate is an effective lubricant for many polymers and can be used as a thermoplastic engineering plastic. It can also be used as an external lubricant for PC, hard PVC and other polymer systems.
