GLS believes these factors all play a role in the decision process and should be used in your decision process. For example, using GLS product XL9070 (SpGr of 0.89) and GLS product G7970 (SpGr of 1.18), both 70A TPEs, the mass of the part in grams is calculated as follows:

Most GLS TPE materials replicate the mold surface fairly well. If a matte finish is required, a rougher mold texture should be used (or a GLS product such as GLS Versalloy™ TPV Alloys, which naturally produce a matte surface).

management uses comparisons of adjusted net income from continuing operations attributable to PolyOne common shareholders, adjusted earnings per share (EPS) attributable to PolyOne common shareholders and adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) 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.
