Traditionally, process aids for extrusion contain fluoropolymers which may be classifiable as per- and polyfluorinated substances (PFAS), a group of chemicals widely used in a variety of applications due to their ability to be water and oil repellent, non-stick, and heat resistant.

The composite material used to make this part includes a custom-formulated thermoset epoxy resin, which also has good corrosion and chemical resistance.

Fiber reinforced composites are a popular material of choice for reliable performance, providing high flexural strength and excellent resistance to heat, moisture, and chemical exposure.

KEY CHARACTERISTICS • High-temperature performance • Excellent impact resistance • Decreased moisture absorption compared to PA66 • Heat stabilized for long-term thermal aging • Enhanced chemical resistance • Customizable formulations in filled and unfilled grades MARKETS & APPLICATIONS The combined performance characteristics make Edgetek Toughened PPA ideal for a range of rigid engine applications.

High-quality conductive pipette tips must meet a number of demanding performance criteria, including: • Accurate measurement of minute quantities of liquid • Hydrophobic properties to minimize fluid retention • Concentric dimensions and warp resistance • Excellent chemical resistance The manufacturer asked Avient for a specialized solution to meet these exacting needs in a timely and efficient manner so they could capitalize on its market opportunity THE SOLUTION Avient’s sales and technical professionals worked closely with the manufacturer to understand the demanding requirements of the end-use application, manufacturing considerations and cost.

FOAMING PREDICITION SERVICE Avient Design uses Autodesk® Moldflow® simulation software1 to provide 3D simulations of parts foamed with Hydrocerol™ Chemical Foaming Agents during the mold filling phase.

Trilliant™ HC chemically resistant blends give outstanding protection to products that must maintain tensile strength integrity after repeated exposure to disinfectants.

Avient engineers also formulated the reinforced polyurethane to chemically bond seamlessly with the urethane used for the outer rolling surface of the wheel.
