In manufacturing processes that involve high temperatures, such as advanced polymer processing and metal die-casting, effective mold release agents are indispensable. Pentaerythrityl Tetrastearate (PETS) stands out as a superior choice due to its exceptional thermal stability and efficacy in facilitating easy part ejection. For product development teams and manufacturing engineers, understanding the advantages and sourcing high-quality PETS is vital.

NINGBO INNO PHARMCHEM CO.,LTD. is a leading manufacturer of Pentaerythrityl Tetrastearate, specializing in producing chemical additives that perform optimally under demanding conditions. Our commitment to quality ensures that our PETS provides reliable mold release properties for a wide array of high-temperature applications.

The Advantage of PETS as a High-Temperature Release Agent

PETS, a complex ester derived from pentaerythritol and stearic acid, offers several key benefits when used as a mold release agent:

  • Exceptional Thermal Stability: Unlike many conventional release agents, PETS can withstand the high temperatures encountered in processing engineering thermoplastics and in metal die-casting without degrading. This ensures consistent performance and prevents contamination of the mold or the product.
  • Superior Non-Stick Properties: PETS effectively prevents molten polymers or molten metals from adhering to mold surfaces, allowing for clean and effortless part ejection. This significantly reduces defects, improves surface finish, and minimizes the need for mold cleaning.
  • Improved Process Efficiency: By ensuring smooth part release, PETS contributes to faster cycle times, increased throughput, and reduced scrap rates in molding operations. This directly impacts manufacturing productivity and cost-effectiveness.
  • Versatility: PETS is compatible with a broad range of polymers, including polycarbonates (PC), thermoplastic polyesters (PET/PBT), polyamides (PA), and various engineering plastics, as well as in metalworking applications.

Applications in High-Temperature Manufacturing

PETS is particularly valuable in:

  • Engineering Plastics Processing: For molding high-performance thermoplastics that require elevated processing temperatures, PETS ensures efficient release and excellent surface quality.
  • Metal Die-Casting: In the die-casting of aluminum, zinc, and magnesium alloys, PETS acts as an effective lubricant and release agent, preventing metal buildup on dies and facilitating smooth ejection of finished parts.
  • Rubber Molding: PETS can also be used in certain rubber compounds to improve mold release and reduce cycle times.
