Very Long Fiber (VLF) Compounds

Our Very Long Fiber (VLF) Compounds are made using a proprietary pultrusion process to create long pellets (11mm) with long fibers inside – the same length as the pellet. When molded, they create an internal skeleton of these fibers which significantly increases impact resistance while also improving strength and stiffness.

VLF compounds are the go-to technology for metal replacement, making them a top choice for automotive and industrial applications because they:

  • are a lightweight and functional alternative to die cast aluminum, magnesium, and zinc
  • maintain performance at extreme high and low temperatures
  • have fiber length of 11 mm , much longer than traditional compounded short glass fibers
  • may improve dimensional accuracy and improve warpage over GF Compounds

Our VLF Compounds come in a number of resin systems, including a Nylon series and a Polypropylene series that can be efficiently injection molded into complex shapes without expensive finishing costs.
