Features Of LAN-XESS Rhenopren EPS Processing Aid

  1. Enhances melt strength and dimensional stability during EPS pre-expansion and molding.

  2. Improves bead fusion uniformity and reduces void formation in final EPS parts.

  3. Compatible with conventional steam-based EPS processing equipment without modification.

  4. Reduces cycle time by enabling faster, more consistent steam penetration and expansion.

  5. Non-toxic, halogen-free formulation compliant with EU REACH and RoHS directives.

Typical Applications Of LAN-XESS Rhenopren EPS Processing Aid

  1. Automotive interior and structural packaging (e.g., instrument panel carriers, bumper molds).

  2. Electronics protective packaging for high-value components and assemblies.

  3. White goods insulation and transport packaging for refrigerators and washing machines.

  4. Construction-grade EPS blocks and geofoam applications requiring high compressive consistency.

  5. Medical device shipping trays requiring clean, low-outgassing expanded polystyrene solutions.
