RIMLINE® LFI

RIMLINE® LFI (Long Fiber Injection) resin is a polyurethane-based, two-component system, developed for use as a core material in the manufacture of lightweight sandwich composite structures. Providing structural support for heavy duty applications, RIMLINE® LFI core system can be overmolded with VITROX® and RIMLINE® resin systems. Using RIMLINE® LFI resin molded core parts can result in thinner panels with improved damage tolerance for load-bearing applications including EV battery protection panels and enclosures.

Materials Features
Key Features
  • Can enable production of composite panels with variable geometries and tunable thickness range
  • Developed for heavy duty and load-bearing applications
  • Can improve damage resistance for sandwich composites with low thickness
  • Tunable processing parameters for short cycle times
  • Can offer a low-cost process for aesthetic parts in medium and large series production
  • Could be combined with in-mold coating, overmolding or thermoformed foils
  • Compatible and complemented with VITROX® and RIMLINE® composite resins
  • Developed for Long Fiber Injection process.
Typical Benefits
  • Moldable - permitting the formation of both thick and thin complex core shapes
  • Increased productivity - a high number of releases are possible and the low amount of residuals can reduce the frequency of tool cleaning
  • Great flow behavior can allow complex core moldings with short cure times
  • Core surface ready for overmolding with composite resins which exhibit very good adhesion without the need for surface treatment*
  • Outstanding property balance for reliable process performance at short cycle times.
