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. 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

In the “Subtotal” section, you can enter values and select tax rates for shipping, handling, and miscellaneous costs. Applicable tax rates are determined by the tax code on the invoice. The tax rate is a government regulated rate to be paid to the tax authorities as part of the sale and is shown as a percentage.
