Gravi-Tech™ Density Modified Formulations PROCESSING GUIDE 2 Gravi-Tech GRAVI-TECH™ Density Modified Formulations Gravi-Tech™ polymer-metal composites are high-density materials developed as thermoplastic-based alternatives to lead and other traditional metals. Gate type should be selected based on location and part geometry. 2. Place these wells at the base of the sprue to capture the cold material first emerging from the nozzle. 2.

They are based on management's expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements. Senior management believes these measures are useful to investors because they allow for comparison to Avient's performance in prior periods without the effect of items that, by their nature, tend to obscure Avient's operating results due to the potential variability across periods based on timing, frequency and magnitude.

Working closely with the manufacturer’s engineers, Avient determined that the material required a special combination of properties: • A heat-resistant base resin that would provide the level of signal dampening prescribed • Mechanical properties that would ensure an effective electrical connection and at the same time allow for snap-fit installation • A cost-effective solution that would enable the manufacturer to compete in this new market Striving for optimal results, the manufacturer evaluated more than 30 different materials. THE IMPACT Avient’s solution was a unique, nylon-based material that met the all of the application’s performance requirements.

PREPERM technology enables a high degree of customization based on individual customer needs. The advantages of PREPERM materials relate to more efficient data transfer (antennas, mobile base stations, satellite communication), better sensitivity (GPS, radars, radomes) and longer battery life (mobile and IoT devices).

IARC’s listing of carbon black as a Group 2B carcinogen is based on laboratory rat studies only; studies on carbon black production workers have not shown a link between carbon black exposure and cancer. COMPANY CONTACT INFORMATION corporateregulatory@avient.com ENVIRONMENTAL EFFECTS Based on its physical/ chemical properties (insolubility, no vapor pressure), Carbon Black released into the environment will be distributed mainly in soil or sediments.

As a result of these plastisol aging characteristics and the potential differences in testing methodology, it is strongly recommended that incoming quality control (QC) specifications not be established based on plastisol Technical Data Sheets (TDS), or Certificates of Analysis (COA). QC specifications should be based on the needs of the process and end product.

Demand for AFO (animal-free-origin) packaging is also becoming more popular; this is due in part to the growing global trends of vegetarianism and veganism, but also as a response to some faith-based requirements such as halal or kosher practices. Eco-conscious packaging compositions are preferred by customers, pushing convertors and brand owners to use sustainable materials—perhaps partially based on renewable or bio-derived sources—that also ensure food contact compliance.

These may include: • Achieve a percentage of all packaging that is reusable, recyclable or compostable • Increase the use of post-consumer recycled (PCR) content, up to 100% • Use lightweighting or other solutions that will help reduce your carbon footprint • Replace petroleum-based materials with renewable materials such as bio-plastics Whatever your goals, we can help you achieve them with customized solutions based on a number of factors.
