Ampacet Corp. has introduced color masterbatches that retard color buildup in plastic extrusion and molding equipment.
The Tarrytown, N.Y., firm said its SmartColor masterbatches shorten the purge time by as much as 60 percent when switching colors.
The compounds also cut the amount of resin needed in purging by as much as 50 percent, which leads to less scrap generation, Ampacet said.
SmartColor resulted from Ampacet's three-year study of raw materials that cause low pigment deposition.
