| CPF 400 Series Fibers are
special blends of acrylic pulp and reinforcing fibers. The
fibers and pulp have been blended in such a way that the short
cut staple fibers will not ball in dry mixed formulations when
introduced into the Littleford or Lodige mixer. Blends with
acrylic staple, melamine, and fiberglass are currently available. The
process has also been demonstrated with carbon, basalt, and aramid
short cut fibers. This technology could be extended to virtually
any short cut staple reinforcing fiber where balling is a problem.
Previous to the development of CPF 400 technology, compounders were
limited to the use of very short fibers of about one millimeter or
less, the use of aramid or acrylic pulps, or the use of controlled
strand integrity fiber bundles. |
