An award-winning group of highly experienced industrial designers, design engineers and prototyping technicians, Avient Design helps customers with all aspects of new product development, from concept to production. Due to the success of this project, the new, lighter heat sink made from Therma- Tech conductive thermoplastics has been rolled out across multiple vehicle models.

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.

Versaflex™ TF Adhesive TPE solutions, developed for adhesive films in laminations with nylon and polyester textile fabrics, enable brand owners and OEMs to create a new generation of soft, stretchable, and breathable fabrics for athletic apparel such as sportswear and underwear. Compared to TPU adhesive films and traditional glue, these new TPE solutions can deliver a seamless and strong adhesion to polyester and nylon fabrics, enabiling a uniform thickness and overall appearance for an athletic, close-fitting, and non-bruising finish.

Ready for testing, the new material was subjected to rigorous environmental testing, including months of sun exposure and long-term placement in humidity-rich environments. Adding to that success, the material’s ability to retain traction when wet opened doors for SurfCo to expand into new markets and applications.

To develop a high-end version with additional features, the design team was seeking a new material. The new material, a GLS™ thermoplastic elastomer (TPE) from Avient, met the rigorous needs of the high-end rifle manufacturer, and then some.
