VW351: Hydrophilic Masterbatch

 
 

Polyvel’s VW351 hydrophilic melt additive masterbatch is an effective wetting agent for melt blown non-woven polypropylene fiber. VW351:

-         Increases melt blown non-woven polypropylene fiber wettability at 5%

-         Makes fiber instantly wettable off line at 6%

 

As the VW351 % in polypropylene fiber increases, the absorptive capacity of a non-woven polypropylene fiber can be increased >4 times that of a non-woven fiber without VW351.
 
 

* Absorptive capacity = number of times weight increased compared to original dry fabric weight (ASTM test method D1117-77)
