Examples
Embodiment 1 to 18 and comparative example 1 to 8
[0076] The above components in the amounts shown in Tables 1 and 2 below were extruded in a common twin-screw extruder and the extruded product was made into pellet form.
experiment example
[0078] By drying the pellets prepared according to Examples 1 to 18 and Comparative Examples 1 to 8 at 100°C for 4 hours, and then using them under the conditions of a plastic temperature of 250 to 270°C and a molding temperature of 60 to 80°C A 10-ounce injection molding machine injection was used to prepare physical samples. The physical properties of these physical samples were measured by the following methods, and the measurement results are shown in Tables 1 and 2 below.
[0079] (1) Impact strength was measured according to ASTM D256 (1 / 8").
[0080] (2) The flexural hardness was measured according to ASTM D790 (2.8 mm / min).
[0081] (3) Heat distortion temperature was measured according to ASTM D648 (18.56kgf).
[0082] (4) Warpage: Inject square samples of 6"X 6"X 1 / 16" film and determine their degree of warpage after ejection.
[0083] Degree of warping: 0 (no warping) → 5 (severe warping)
[0084] (Table 1)
