ST EPS Coating Agent (Senthos 442) – Anti-Lumping & Mold Release Expert

Product Overview

ST EPS Coating Agent, specifically known as Senthos 442, is a sophisticated blend of multiple functional additives, including GMS (Glycerol Monostearate), GTS (Glycerol Tristearate), and Zinc Stearate. Developed through our proprietary production process, this EPS Coating agent is designed to provide excellent free-flowing properties and stable adhesion to EPS beads, ensuring it does not easily fall off during processing.

Key Performance & Advantages

  • Lumping Prevention: Senthos 442 is specially developed to reduce lumping during the EPS bead pre-expansion stage significantly.

  • Better Flow & Uniformity: It helps control the leakage of forming agents, resulting in more uniform beads with enhanced free-flowing properties into the mold.

  • Improved Mold Release: By enhancing the melting ability of pre-expansion beads and maintaining heat balance, it significantly improves mold release properties and reduces the reject ratio.

  • Shape Retention: It helps maintain the finished EPS product’s precise shape after cooling.

Packaging & Shelf Life

  • Packaging: Standardized in 15kg paper cartons for easy handling and storage.

  • Shelf Life: 12 months when stored in original, unbroken bags under required storage conditions.
