This company recently announced the introduction of its new line of OMNABONDTMself-crosslinking styrene butadiene polymers for the nonwovens, coatings, and construction markets.
polymers offer improved wet and dry tensile properties, filler acceptance,
color fastness, caustic resistance, and adhesion to both synthetic and natural
fibers as well as lower levels of formaldehyde, which can be important to
health and environmental concerns.
tensile strength performance of OMNABOND polymers make them ideal for a number
of short- and long-life nonwoven applications including towels, wipes and
filtration media, as well as a variety of other specialty uses. This enables
for lower binder levels, which makes OMNABOND polymers an ideal substitute for
other polymer chemistries, including vinyl acetate ethylene (VAE) and acrylic
addition, their accelerated cure rate reduces or eliminates the need for an
external catalyst to achieve optimal performance. They also can be combined
with external crosslinkers, like melamine and urea formaldehyde (UF) resins for
long-life applications, including commercial roofing binders.
self-crosslinking styrene butadiene polymers are available in a range (-25° C
to 35° C) of glass transition temperatures. The product line complies with FDA
regulations 21 CFR 176.170 and 176.180, for contact with food products.
