CUSTOM FORMULATION IMPROVES PRODUCTIVITY AND MANUFACTURING EFFICIENCY CASE STUDY: TRILLIANT™ HC SPECIALTY ENGINEERED MATERIALS Challe nge Accepted. 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. THE IMPACT For the manufacturer, Trilliant™ HC specialty engineered materials provided a number of advantages that contributed to the success of the new product line: • Reduced Cycle Time: The high flow properties of the Trilliant HC formulation allowed the manufacturer to produce warp-free parts that require less packing and cooling time, resulting in a 40% cycle time reduction. • 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%. • Reduced Scrap Rate: The consistent conductivity, improved warp resistance, reduced flash, and improved durability provided by the Trilliant HC formulation meant less breakage, fewer rejects and a 40% reduction in scrap rate. • Total Manufacturing Cost Savings: Despite an increase I price per pound over the competition, the manufacturer’s total cash costs were reduced by over $45,000 on an annualized basis as a result of the proven, quantified savings in cycle time, productivity and scrap.

These DBDPE-free grades satisfy regulatory and performance demands by using an alternative flame retardant while maintaining UL 44 compliance and comparable performance to traditional Syncure XLPE materials. The development of these high-performing materials grants wire and cable producers the flexibility to adapt to evolving regulations in the market.
