Forward-looking statements give current expectations or forecasts of future events and are not guarantees of future performance. They use words such as “will,” “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” and other words and terms of similar meaning in connection with any discussion of future operating or financial performance and/or sales.  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 realize anticipated savings and operational benefits from the realignment of assets, including the planned closure of certain manufacturing facilities;  The timing of closings and shifts of production to new facilities related to asset realignments and any unforeseen loss of customers and/or disruptions of service or quality caused by such closings and/or production shifts;  Separation and severance amounts that differ from original estimates and amounts for non-cash charges related to asset write-offs and accelerated depreciation realignments of property, plant and equipment, that differ from original estimates;  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 and retain relationships with customers of acquired companies including, without limitation, Spartech Corporation and Accella Performance Materials;  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;  The financial condition of our customers, including the ability of customers (especially those that may be highly leveraged and those with inadequate liquidity) to maintain their credit availability;  The speed and extent of an economic recovery, including the recovery of the housing market;  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 materials in jurisdictions where we conduct business;  Changes in global industry capacity or in the rate at which anticipated changes in industry capacity come online in the industries in which we participate;  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;  An inability to raise or sustain prices for products or services;  An inability to maintain appropriate relations with unions and employees;  Our ability to continue to pay regular quarterly cash dividends and the amounts and timing of any future dividends;  The amount and timing of repurchases of our common shares, if any;  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  The above list of factors is not exhaustive.  We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise. Senior management uses operating income excluding special items, adjusted EPS, and working capital to assess performance and allocate resources because senior management believes that these measures are useful in understanding current profitability levels and that current levels may serve as a base for future performance.

It’s how we meet the needs of the present without compromising the ability of future generations to do the same. So as we reflect on the past year—and more importantly, as we look to the future—we do so with a great sense of pride and optimism. Composites and additives are delivering today, and we expect they will continue to grow well into the future.

Suspicious areas were then subjected to chemical analysis, in which the primer, adhesive, and titanium surfaces revealed potential factors that could compromise bonding integrity.

PA 6,6 Wider processing temperature range Better surface quality Better weathering resistance Shorter conditioning time—nearly half that of PA 6,6 DRAWBACKS VS.

This simple addition to your design offers a practical way to improve your product’s surface quality, add custom color and sensory effects, and it works with most substrates.

Processors using Excelite IM additives between 0.12% and 0.5% can achieve density reductions, smoother surface finishes and reduced sink marks while generating a tighter cell structure.

They are also compatible with SMT (Surface Mounting Technology) methods of circuit board production because they can be formulated with high heat resistance.
