Americhem Inc. has hit the century mark with Censtron 100:1, a new line of color concentrates that can color 100 pounds of resin for each pound used.
Censtron 100:1 was commercialized earlier this year at one of two plants near Americhem headquarters in Cuyahoga Falls, Ohio. The materials are produced in polypropylene and ABS grades and are aimed at automotive applications, primarily interior hard trim parts such as door panels and pillars, according to automotive sales manager Denny Ferrell.
``In the automotive world, they're constantly pressing for cost reduction,'' Ferrell said in a recent telephone interview. ``Now we can give them that with a highly loaded concentrate and the right mix of [ultraviolet light] stabilizers and heat stabilizers.''
Traditional molded-in-color applications have used concentrates of 25:1 to 50:1, Ferrell added.
``We had to let the molding world catch up before we could introduce this product,'' he said.
The material and process technology used to make Censtron also could be used in other resins, although Americhem has no plans to do so at present. If market acceptance accelerates, Censtron could be made at any of Americhem's seven other plants as well.
Censtron also has potential in construction applications such as PP cedar-shake panels.
Americhem also is focusing on the cost savings Censtron can offer molders because of its higher loadings.
``Molders want to pay for pigments and additives, but not for the carrier resin,'' Ferrell said. ``So Censtron yields savings because it lets them use less carrier resin.''
