KEYSTONE’S LINE OF POLYPROPYLENE
POLYPRO® is a high quality filament for a wide variety of applications. Its many features include excellent stiffness when wet. More rugged than shaped fibers, POLYPRO® is the product of choice for tough scrubbing applications.
POLYPRO® (FLG) is a flaggable, softer fiber. It has a more slippery surface for ease of picking in certain applications. It is the most popular of several inexpensive flaggable POLYPRO® formulations.
POLYPRO® and POLYPRO® (FLG) may be purchased unflagged. POLYPRO® (FLG) is a pro based product containing SAN for applications needing solvent resistance.
POLYPRO® (FLG) contains styrene and is more suitable for dry applications.
POLYPRO® Tri-Star is a triangular shaped polypropylene fiber that was developed as a Tampico fiber replacement. It is a high yield fiber, making twice as many brushes per pound as PVC. It is excellent for household, hardware and industrial brushes.
KEYKORN® is an X shaped fiber designed to provide a multi-surface cross section for high yield and improved liquid retention. KEYKORN® filaments were specifically designed for an upright household broom. They are intended as replacements for natural broomcorn.
