Tensile modulus and tensile strength of the RPET compounds increased when adding with talc filler as shown in
Fig. 3 (a) and Fig. 3 (b), respectively. From the results, tensile modulus of the talc filled RPET compounds by the
water cooling was higher than air cooling system, which might be due to large amorphous fraction in these
compounds. On the other hand, tensile strength of the RPET compounds was almost unchanged when using the air
cooling or the water cooling processes
