Poly Bristle

POLYPROPYLENE FILAMENT Keystone’s line of polypropylene filament is top quality and versatile for a wide variety of applications. It has excellent wet stiffness, flex fatigue resistance and good bend recovery. POLYPRO and KEYKORN are inert to most solvents, oils and chemicals and are especially good at resisting acids and bases. Polypropylene offers a 50% better yield than PVC. It has limited natural sunlight resistance, which may be greatly improved by the addition of black color.

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.
