March 19, 2025 – Polyester wax has emerged as a versatile workhorse in the plastics industry, offering a multitude of benefits and conveniences in plastic processing. Its multifaceted applications have significantly enhanced the efficiency and quality of plastic manufacturing.
In the realm of engineering plastic modification, polyester wax serves as an invaluable assistant. It effectively improves the fluidity of plastics, facilitating smoother molding processes and enhancing demolding performance. Moreover, during high-temperature injection molding, polyester wax plays a crucial role in reducing labor hours and boosting production efficiency. When added as a dispersant in polyamides along with reinforcing materials and pigments, it ensures uniform distribution, thereby elevating product quality.
According to ColorMasterbatch Industry Network, polyester wax also excels in PET/PBT applications. It notably enhances the demolding and fluidity characteristics of PET/PBT, particularly demonstrating optimal performance in filled PET/PBT, providing robust support for the production of related products.
In the processing of thermoplastic polyurethanes, polyester wax is indispensable. It imparts excellent demolding effects without migration issues. Especially in pigment dispersion within masterbatches, polyester wax significantly increases dispersion speed, ensuring more uniform pigment distribution throughout the plastic.
For thermosetting plastics, polyester wax makes a unique contribution. As an internal lubricant, it improves the fluidity of thermosetting plastics, while external lubricants reduce adhesion between the material and hot machine parts, further enhancing demolding effects and ensuring smooth production processes.
Furthermore, polyester wax serves as a valuable additive in engineering plastic processing, significantly improving processing performance for more efficient and stable plastic manufacturing. It also acts as a carrier for pigment concentrates, enhancing pigment dispersion and stability, thereby providing better assurance for pigment application in plastics.
