THE CHALLENGE A manufacturer of high-quality laboratory research products was eager to expand into the conductive pipette tip market. Avient determined that the manufacturer required a material with a unique combination of properties, including: • Processing ease – high flow rate, ability to fill multi-cavity molds, thin-wall capabilities • Superior toughness – strength and durability to ensure dimensional integrity of the part • Repeatable performance – consistent conductivity for accurate measurement of liquids While several off-the-shelf compounds were evaluated, a new formulation was developed to meet the manufacturer’s specific needs as well as provide signifi cant benefi ts in reduced cycle time, increased production and reduced scrap rate. Increased Production: Additionally, the high flow properties of the Trilliant HC formulation allowed for an increase in the number of cavities in the mold, resulting in a machine cost-per-part savings of over 30%
