As shown in Figure 3, adding other carbohydrates to the isolate caused only a small drop in wet strength
but the results varied with type of carbohydrate.
The best results were obtained in experimental manufacture by using fiber furnishes of 100-percent strong bleached sulfate pulps with melamine-formaldehyde resin for wet strength
and titanium dioxide for opacity.
Figure 3 shows the effect of chaotropic agents (urea, guanidine hydrochloride, dicyandiamide, and lithium perchlorate) on dry and wet strength
with 5 percent PAE polymer.
Its wet strength
integrity also makes it an ideal base sheet for wet wipes.
The HMR primer produced no significant increases in wet strength
in any of the three wet tests.
This portfolio is known for its high strength, printability, convertibility and broad range of grease resistant, PFOA free and wet strength
Previously, there was more allowance of flexible specifications and tolerances with uncoated wet strength
sheets," says Wilson.
Voith Paper and Triitzchler have jointly developed a manufacturing process, using cellulose, to make wetlaid and hydroentangled nonwovens with a high level of wet strength
89 gsm) heavyweight wet strength
label paper designed for large glass and plastic containers used in food, beverage and condiment applications.
The patent-pending polymer system, Nacrylic STP, adds value to chemically bonded wipes by supporting the wet strength
requirements of products containing lotions and by triggering the wipe to fully disperse while in the presence of excess water.
Functional chemicals, on the other hand, impart a needed quality to the finished product such as wet strength
, water resistance, etc.
The adhesive based on the improved hardener can be used to glue wood particles to pass wet strength
requirements after the glue is cured at room temperature for under 24 hours.
Excellent Wet Strength
for Membrane Handling and Integrity
These labelstocks also feature adhesives tailored to increase automated packaging and offer exceptional wet strength
on bottles and cans.
The first innovation, NEXAR polymers, provides a route to membranes having high water transport rates, excellent wet strength
, and good selectivity.
