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.
- 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.
- 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
- Injection molding
