Celstran® long fiber reinforced thermoplastics (LFRT) unite long fiber reinforcements with advanced thermoplastic resins for a combination of mechanical properties, impact, creep resistance and low warpage.

Incorporated fibers can be glass, carbon, aramid and stainless steels. Nearly all types of polymers are suitable as matrix material.


Product Properties

  • Markedly higher mechanical properties
  • High notched impact strength
  • Reduced creep
  • Very good stability over a broad range of temperatures and climatic conditions

It is produced by pultrusion technology — the long fibers are impregnated to deliver optimal reinforcement to the plastic matrix. Unlike conventional short-fiber reinforced materials, the longer fibers form an internal glass fiber “skeleton” that limits anisotropic shrinkage and greatly reduces warpage in parts.

Grades

  • Matrix materials: PP, PA (further matrix materials on request)
  • Glass fiber reinforced: fiber content 20 to 60 percent
  • Carbon fiber reinforced
  • Aramid fiber reinforced
  • Stainless steel filaments for EMI and RFI shielding

Processing

  • Injection molding
