Chopped Strands

Properties

  • Excellent strand integrity
  • Good flowability
  • Good fibre dispersion in the extruder
  • Excellent mechanical properties of the moulded parts
  • No discoloration
  • Good surface appearance of the moulded parts

Glass fiber roving strand chopped to a specified length is used as reinforcing material in combination with
thermoplastic resins for injection molding. Depending upon the application, a strand may contain several
hundreds of monofilaments with diameters ranging from 10 µm to 13 µm. The cutting length is 3 mm.
Surfaces of monofilaments are specially coated with a suitable sizing which is compatible with the
thermoplastic resins.
