Effect of conditions on the rheological and mechanical properties of virgin and recycled poly(butylene terephthalate)/polycarbonate/ acrylonitrile-butadiene-styrene (PBT/PC/ABS) blends was investigated in injection molding by using Taguchi's experimental design. PBT, PC, and ABS polymers were compounded in an extruder to obtain ternary blends. Blend was recycled five times. Injection pressure, holding pressure, and injection temperature were taken into consideration as the input. Ratio of signal-to-noise (S/N) was employed to determine whether optimum conditions of control inputs could be used to achieve the highest properties. Analysis of variance was used to determine how inputs affect outputs.

“…In the Taguchi method, determining the mean signal to noise ratio (S/N) for each processing parameter is an important step to assess quality characteristics of the measured data, to compare the relative magnitudes, and to find the optimal combination of processing parameters for desired mechanical properties. The equation for calculating the mean S/N ratio is given later

{\overset{true¯}{S / N}}_{A_{i}} = \frac{1}{n} true {true\sum}_{i = 1}^{n} S true/ N_{A_{i}}

S true/ N_{A_{i}}

The optimum condition of processing parameters (mixing temperature, rotor speed, fill factor, and blend ratio) and prediction models for the best key mechanical properties of ethylene propylene diene terpolymer/polypropylene thermoplastic vulcanizates (EPDM/PP TPVs) was investigated by using the Taguchi's optimization technique and data analysis. The results reveal that all of the processing parameters affected significantly the mechanical properties of the EPDM/PP TPVs, but specifically the blend ratio contributed more than 90% in effect size on tensile strength and tension set. There were three main factors, the mixing temperature, the fill factor, and the blend ratio, influencing the elongation at break. Furthermore, the mathematic models were effective and reliable in predicting the properties of TPVs. The correlation of mechanical properties, stress relaxation, and phase morphologies of the TPVs prepared from the predicted models was also investigated. It can be summarized that the morphological structure and stress relaxation of the TPVs were strongly governed by the EPDM content in the blend ratio. That is, the higher the EPDM content, the better phase morphology having smaller size of the vulcanized EPDM particles distributed in the PP matrix and the higher rate of stress relaxation. Moreover, these two properties were then principally pushing the mechanical characteristics of the EPDM/PP TPVs. Copyright © 2015 John Wiley & Sons, Ltd.
