Clariant developed new technology for polyolefin blow molding

May 18/2012
(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.
