Speciality chemical company Clariant has developed a new liquid vehicle technology (LVT) ideal for monolayer extrusion blowmolding.
The company states the new LVT appears to eliminate many of the problems that have prevented wider use of liquid color and additive concentrates in extrusion blowmolding of polyolefins.
"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," stated Raymond Sloan, head of liquid color, Clariant Masterbatches North America, in a news release. "However, until now, use of liquid color has been limited in blow molding of polyolefin resins because many liquid based carrier systems (including mineral oil) would not incorporate well with the resins. It was pigment friendly, but not resin friendly."
