POLYESTER FIBERS

POLYESTER FILAMENT PROPERTIES

  • Excellent solvent resistance
  • Excellent oxidation resistance
  • Does not absorb water
  • Good abrasion resistance
  • Excellent bend recovery
  • Excellent heat resistance

PLYER® is the Monahan Filaments brand name for fibers made with polybutylene terephthalate polyester (PBT). Plyer® offers superior bend recovery compared to PET Polyesters. Plyer® is an economical substitute for nylon 6.6 or 6.12 in many applications. It has better abrasion resistance than polypropylene or polystyrene, but not as good as nylon. It also has excellent bend recovery, excellent solvent resistance and excellent oxidation resistance at high temperatures. Plyer® has very good resistance to sunlight. The properties of Plyer® do not change significantly between wet and dry applications because it does not absorb much water. This makes it the ideal material for many wet applications. Typical ovality ranges from 1.01 for 0.008” to 1.65 for 0.070”.

PLYER® was developed as a replacement for horsehair, as it has an appearance and feel quite similar to horsehair. It offers many of the same properties as the nylons, but absorbs very little water; therefore, Plyer® holds its stiffness in wet applications. This material is a multipurpose fiber used in industrial, personal care and food service brushes. Plyer® is available in formulations FDA-approved for food contact.

PLYER® X fibers offer increased liquid retention and better yield. They are available in three weights: light, medium and heavy shapes.
