(clariant) -- New
liquid vehicle technology (LVT) developed by Clariant Masterbatches appears to
eliminate many of the problems that have prevented wider use of liquid color and
additive concentrates in extrusion blow molding of polyolefins (high- and
low-density polyethylene and polypropylene).
Initial testing in
monolayer containers shows that these highly compatible systems allow for higher
pigment loadings and lower usage rates, while practically eliminating past
challenges related to screw slippage. Improved resin compatibility results in
stronger weld lines in the finished container as evidenced by scores in standard
burst and compression-loading tests.
"Extrusion blow molders and brand
owners in the personal care and household products markets often find liquid
masterbatches to be an attractive alternative to solid concentrates," says
Raymond Sloan, Head of Liquid Color, Clariant Masterbatches North America.
The new Clariant masterbatches use a liquid vehicle system that
incorporates suspension aids and binders have been incorporated into the new LVT
masterbatches to allow for higher pigment loadings and lower usage rates.
