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 a 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. 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
