Please contact your Avient account manager for more information. Ejector Sleeves An ejector sleeve is a hollow pin that slides along a core pin, which delivers a larger contact area . The total Mold Base Width = Cheek + Part Width + Contact Width ( .500") + Space between cavities .

For specific interactions to occur between the TPE and the substrate, both have to come in intimate contact to each other on a molecular level and wet out the surface. NYLON OVERMOLDING TECHNOLOGIES Relying on the presence of the polyamide structure in the TPE composition to generate a strong bond when the molten blend comes into contact with a nylon substrate, US patents 5,843,577 (2) and 5,750,268 (3) disclose TPE blends for nylon overmold.

Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: • Our ability to identify and evaluate acquisition targets and consummate acquisitions; • The ability to successfully integrate acquired companies into our operations, retain the management teams of acquired companies, retain relationships with customers of acquired companies, and achieve the expected results of such acquisitions, including whether such businesses will be accretive to our earnings; • Disruptions, uncertainty or volatility in the credit markets that could adversely impact the availability of credit already arranged and the availability and cost of credit in the future; • Our ability to achieve new business gains; • The effect on foreign operations of currency fluctuations, tariffs and other political, economic and regulatory risks; • Changes in polymer consumption growth rates and laws and regulations regarding the disposal of plastic in jurisdictions where we conduct business; • Changes in global industry capacity or in the rate at which anticipated changes in industry capacity come online; • Fluctuations in raw material prices, quality and supply and in energy prices and supply; production outages or material costs associated with scheduled or unscheduled maintenance programs; • Unanticipated developments that could occur with respect to contingencies such as litigation and environmental matters; • An inability to achieve or delays in achieving or achievement of less than the anticipated financial benefit from initiatives related to working capital reductions, cost reductions and employee productivity goals; • Information systems failures and cyber attacks; • Our ability to continue to pay regular cash dividends and the amounts and timing of any future dividends; and • Other factors affecting our business beyond our control, including, without limitation, changes in the general economy, changes in interest rates and changes in the rate of inflation.
