This hard/soft combination design has been driven by an escalating market trend pushing toward enhanced ergonomic feel and touch, gripping feel, aesthetics, cushioning against impact, vibration isolation or dampening and insulation. Rigid thermoplastics include both commodity thermoplastics and engineering thermoplastics, such as polypropylene (PP), polystyrene (PS), high impact polystyrene (HIPS), polycarbonate (PC), acrynitrile-butadiene-styrene (ABS), poly(ethylene terephthalate) (PET), poly(methylmethacrylate) (PMMA), styrene acrylonitrile (SAN), poly(phenylene oxide) (PPO), polyamide (PA), PC/ABS blend and PPO/PS blend etc.. As given in Table 2, TPE-1 demonstrates good adhesion on all ten substrates with very different surface energy and polarity; from the low like PP to the high like PC and ABS.

 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 closure of manufacturing facilities;

As shown in figure 2, in high shear rate regimes, the viscosity is at the lower end of the spectrum which helps the TPE to flow into and fill the thin-walled sections commonly encountered during overmolding. These include semi crystalline and amorphous polymers such as polypropylene, high impact polystyrene (HIPS), polycarbonate (PC), polystyrene (PS), acrylonitrile-butadiene-styrene (ABS), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polymethyl methacrylate (PMMA), styrene acrylonitrile (SAN), polyphylene oxide (PPO), polyoxymethylene (POM) and polyamide (PA). Overmolding TPE for Acetal and their Copolymers: Acetal is an abrasion resistant high performance polymer with a high degree of crystallinity (>98%).

When showing constant dollar figures on GAAP and non-GAAP financial measures, the foreign exchange impact is calculated by using current foreign exchange rates and applying them to the prior period results. Unless otherwise stated, Adjusted EBITDA figures included in this presentation exclude the impact of special items as defined in our quarterly earnings releases. We also monitor earnings (defined as net income from continuing operations) before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA (EBITDA before the impact of special items) as a supplement to our GAAP measures.

However, the way we add color to our products can have a big impact on our business success, and the textile industry is also under pressure to become more agile and also more sustainable. It works by injecting liquid color at high pressure into the polyester melt-flow between the end of the extruder, or melt-pipe, and the spin head. FIBER SOLUTION SERVICES LABORATORY PERFORMANCE BASED ON STATE-OF-THE-ART TECHNOLOGY To ensure the highest quality products, our customers rely on high- performance raw materials which guarantee that the final products meet the required specifications for heat resistance, household washing, weathering and lightfastness.

Senior management has referenced adjusted EPS excluding the impact of additional shares issued in February 2020. This guidance excluded the impact of the additional shares subsequently issued in February. For purposes of comparability to the prior year, senior management has referenced adjusted EPS excluding the impact of additional shares issued in February 2020, as well as the impact of the senior unsecured notes offering completed in May 2020.
