THE SOLUTION Gravi-Tech™ density-modified formulations are unique, high-density materials developed as thermoplastic-based alternatives to lead and other traditional metals. Thanks to the customized Gravi-Tech material, API was able to successfully design and mold a flapper valve that is the only one of its kind on the market—and offers a less expensive solution than traditional brass valves.

These polymer formulations have been developed to achieve equivalent performance to prime density modified solutions with added sustainability benefits. KEY CHARACTERISTICS • Customized density offering a wide range of specific gravities (1.5–11 gm/cm3) • Formulated with partially bio-based resin from renewable plant sources • Broad modulus range, from very flexible to very rigid grades • Corrosion resistance that withstands oxidization for long-term use and benefit • Chemical resistance that can be adapted depending on base resin as required • Provides visual surface effects, aesthetics and cool touch • Design flexibility and processing ease • Food contact compliance available MARKETS AND APPLICATIONS Applications in packaging and consumer goods in which a more sustainable solution is preferred: • Cosmetic caps and closures • Perfume caps • Spirit bottle caps • Luxury boxes • Handles and knobs SUSTAINABILITY BENEFITS • Formulated with partially bio-based resin from renewable plant sources • Reduces waste and supports the circular economy • Reduces carbon footprint compared to fossil feedstock alternatives • Simplifies manufacturing and lowers cost versus metal PRODUCT BULLETIN CHARACTERISTICS UNITS Gravi-Tech BIO GT5200-5077 FD Natural Gravi-Tech BIO RS5200-5001 RS FD Natural Gravi-Tech BIO RS5200-5001 RS FD Natural X1 Gravi-Tech BIO GT5200-5003 Gravi-Tech BIO GT5200-5004 Gravi-Tech BIO GT5200-5002 Base Resin Bio-based PP Bio-based PP Bio-based PP Bio-based PP Bio-based PP Bio-based PP Recycled Content/Filler g/cm Mineral Mineral Mineral Metallic Metallic Metallic Density (ISO 1183) g/ccm 1.90 2.0 2.0 2.0 2.5 3.0 AVAILABLE GRADES Copyright © 2023, Avient Corporation.

FINDING THE LATEST TECHNOLOGIES VISUALIZING THE POSSIBILITIES HOW CAN I BE SURE I’VE SELECTED THE SOLUTION THAT’S BEST FOR MY DESIGN AND BRAND? We follow the solution from our design centers to your plant, supporting development trials and scale up, and troubleshooting production issues as they arise.

Conductive pipette tips must meet demanding performance criteria and therefore require a polymer solution with a unique, and often difficult to achieve, blend of properties. Working together, we can help you arrive at an optimal solution with speed and accuracy, while helping to lower product development and manufacturing costs.
