Features Of LAN-XESS RHENOFIT 3555 Processing Aid

  1. High-efficiency internal lubricant for improved melt flow and reduced extrusion torque.

  2. Thermally stable up to 220 °C, supporting high-speed processing of engineering thermoplastics.

  3. Low volatility and minimal plate-out, ensuring consistent die cleanliness and extended production runs.

  4. Compatible with polyamide (PA6, PA66), polypropylene (PP), and thermoplastic elastomers (TPE).

  5. Non-migrating formulation that maintains surface integrity and avoids interference with downstream bonding or painting.

Typical Applications Of LAN-XESS RHENOFIT 3555 Processing Aid

  1. Injection molding of reinforced polyamide components for automotive under-hood applications.

  2. Extrusion of thin-walled PP profiles used in appliance housings and consumer electronics enclosures.

  3. Compounding of flame-retardant engineering plastics requiring low-smoke and low-corrosivity performance.

  4. Two-shot molding processes involving thermoplastic polyurethane (TPU) over polypropylene substrates.
