Due to rigid polycarbonate test specimen breakage, we were unable to obtain 14-day and 28-day plasticizer-induced stress cracking data on most of the polycarbonate samples. The data in Table 2 demonstrates a surprising correlation between plasticizer viscosity and that plasticizer’s ability to induce stress cracking in both rigid PVC and .
TEST METHODS . The compounds for performance testing were mixed in a BR Banbury internal mixer . following standard mixing procedures. Curatives were withheld from the Banbury charge and added on a two -roll, 611 x 1311 laboratory mill during finishing operations. Test specimens for compound performance properties were molded at 180 °C for 10
In Study 3, like Study 2, the level of plasticizer was held constant. 3 The ingredients were mixed in a planetary mixer and then placed on a two-roll mill for 10 minutes at 163°–166°C. This milled sheet was then compression molded to the desired thickness (40 mil/1 mm) for 8 minutes at 174°C and 145 kPa (1000 psi).
Performance testing of a green plasticizer based on lactic acid for PVC. . Second, the mixture was compounded at 160 °C for 5 min by using a double-roll mill (Yunxin Co., China). Then, the films were made using a hot press (Yunxin Co., China) at 180 °C for 2 min. The blends were cooled to room temperature to obtain soft PVC samples.
A 10:1 volumetric ratio of A to B side was mixed together until the color was uniform, then passed through the three roll mill once. The sample was applied to a 1 in 2 area of substrate. Then, a second substrate was applied to the top and placed in a jig following ASTM C961.
The process using a roll mill at room temperature and roll speed of 20 rpm. The vulcanization process carried out at a temperature of 150 ° C and a pressure of 200 kgf/cm 2 using a hot press.
