Celanese - The chemistry inside innovation^™

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

Processing
