Hydrophobics

hydroheader

Polyvel's hydrophobic masterbatches provide excellent water, alcohol and blood repellency  to polypropylene nonwovens in a uniform, low dusting, pellet form that allows for cleaner, more consistent, incorporation than topically applied alternatives. 

Product: HydRepel
Industry: Fiber Manufacturing
Function: Hydrophobic masterbatch for PP nonwoven fiber

HydRepel

For over 10 years Polyvel has marketed and produced the HydRepel line of hydrophobic additive concentrates for polypropylene (PP) melt blown, spun bond, composite fabric applications. These products increase hydrophobicity and impart alcohol repellency to nonwoven polypropylene fabric. The repellency is useful in both medical and construction applications.

HYDREPEL A-204S and A-204M are designed for uniform melt mixing in fiber extruders and are cost–effective compared to topically applied repellents. and A-204M are designed for uniform melt mixing in fiber extruders and are cost–effective compared to topically applied repellents.

HYDREPEL A-204S and A-204M are designed for uniform melt mixing in fiber extruders and are cost–effective compared to topically applied repellents. has proven performance on Reicofil 3 and Reicofil 4, SB and SMS equipment. Excellent extrusion performance, high alcohol repellency and improved fabric softness are achieved without loss to HSH, MC/CD tensiles or other fabric properties.


Debuting in 2018 is our newest hydrophobic, HydRepel 720. Polyvel has developed a new-to-market hydrophobic additive concentrate in response to customer interest in a more cost-efficient solution to imparting alcohol repellency to nonwoven polypropylene fabric for medical, hygiene, filtration, and construction applications. The biggest differentiator is the ability for this additive package to reach AR values of 8+ at lower dosing levels AND with in-line heat treatment or steam sterilization.
