Monahan Filaments PROSTRAN^® polypropylene is a top quality, versatile filament for a wide variety of applications. It has excellent wet stiffness and flex fatigue resistance.

PROSTRAN^®is inert to most solvents, oils and chemicals and is especially good at resisting strong acids and bases. It has good bend recovery but will take a set more easily than other materials. This problem can be easily addressed with good brush design and reasonable care in handling and packaging. PROSTRAN^® offers a 50% better yield than PVC. It has limited natural sunlight resistance, which may be greatly improved by the addition of black color or UV stabilizer. PROSTRAN^® products are differentiated by shape. Ovality for PROSTRAN^®, PROSTRAN^® FTR, PROSTRAN^® FTY and PROLUBE runs from 1.02 for small diameters to 1.50 in larger diameters.

PROSTRAN^® is a high quality filament for a wide variety of applications. Its many features include excellent stiffness when wet. More rugged than shaped fibers, PROSTRAN^® is the product of choice for tough scrubbing applications.

PROSTRAN^® PROLUBE is a flaggable, softer fiber. It has a more slippery surface for ease of picking in certain applications.

PROSTRAN^® FTY & FTR are the most popular of several inexpensive flaggable PROSTRAN^® formulations. PROSTRAN^® FTY and FTR may be purchased flagged or unflagged. FTY is a pro based product containing SAN for applications needing solvent resistance. FTR contains styrene and is more suitable for dry applications.

POLYSTAR-O^® 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.

PROEX^® is an X-shaped fiber designed to provide a multi-surface cross section for high yield and improved liquid retention.

POLYCORN^® filaments were specifically designed for an upright household broom. They are intended as replacements for natural broomcorn. The Polycorn^® material is flaggable, whereas the Polycorn P is not flaggable, 100% polypropylene. It is available in controlled weight bundles.

PROPE^® HOLLO^® is a hollow polypropylene filament where high yield is necessary.

POLYBASS^® is a 100% polypropylene fiber. It is a heavy duty, X-shaped, two color, two diameter fiber. This fiber was designed as a replacement for African Bass fiber. It is used in street brooms, push brooms, barn brooms and upright brooms. Polybass^® will also run much more easily and cleanly, with less waste in your brush making machinery than natural fiber.

POLYPALM^® I & II are light weight, very attractive, long wearing 100% polypropylene X-shaped fibers designed to replace Palmyre and Bassine. The Polypalm^® I is a two-diameter, two color fiber that is a very good material for push-brooms. Polypalm^® II is a one color 0.024" diameter version of Polypalm^® I. Both materials run much more easily and cleanly, with less waste in your brush making machinery than natural fiber.

POLYMET-O^® is a heavy gauge two diameter, two color filament designed specifically as a Palmyra replacement product. Lightweight but coarse, this product is ideal for heavy sweeping applications.

PROSTRAN^® C/L provides excellent cleaning action and durability. The clover leaf shape gives greater yield and improved sweeping. Prostran^® C/L is available in 0.012" to 0.060" diameters, level or crimped, and in PVC wrapped bundles.

PROPYLITE^® is a blend of polypropylene and polyethylene in hollow construction producing an economical and high yielding filament.

POLYUNION is MFI's synthetic alternative for natural Union mix. This three diameter, three color, two profile crimped material closely resembles its natural counterpart and is excellent in any heavy scrubbing applications.

DURAPALM^® is a multicolor, multi-diameter, durable, lightweight and cost effective alternative to natural Palmyra. Durapalm^® features a smooth, consistent texture that resists water, chemicals and bug infestation. Available in two stiffnesses, DuraPalm^® I and DuraPalm^® II offer improved efficiencies for the manufacturer and effective tools for the end use.
