ΣΥΜΒΟΛΗ ΣΤΗ ΜΕΛΕΤΗ ΤΗΣ ΕΛΑΣΤΙΚΗΣ ΣΥΜΠΕΡΙΦΟΡΑΣ ΤΩΝ ΕΛΑΣΤΟΜΕΡΩΝ ΑΠΟΤΥΠΩΤΙΚΩΝ ΥΛΙΚΩΝ ΠΟΛΥΒΙΝΥΛΣΙΛΟΞΑΝΗΣ

AN EXPERIMENTAL STUDY ON THE ELASTIC BEHAVIOUR OF THE POLYVINYL- SILOXANE ELASTOMERIC IMPRESSION MATERIALS HAS BEEN MADE. YOUNG'S MODULUS OF ELASTICITY HAS BEEN STUDIED AS WELL AS SLOPE B OF THE DL-F DEPENDENCE CURVE IN THE ELASTIC AREA.ALSO, PERMANENT DEFORMATION AND FRACTURE LIMITS WERE STUDIED. FOR THIS PURPOSE25 POLYVINYLSILOXANE IMPRESSION MATERIALS WERE USED IN THE DIFFERENT FORMS OF CONSISTENCY THAT MAY BE OBTAINED. FOR THE STUDY OF EACH MATERIAL SAMPLE, CYLINDRICAL SPECIMENS WERE MADE HAVING 3,6MM DIAMETER BASE AND A HEIGHT OF 50MM. THESE SPECIMENS WERE ELONGATED BY SUSPENDING SUCCESSIVE LOADS. ELONGATION READING WERE BEING TAKEN FOR EVERY LOAD INCREASEMENT WITH A PERPENDIONLOMETER. FOUR CONSECUTIVE READINGS WERE TAKEN FOR EVERY MATERIAL SAMPLE STARTING AT SETTING TIME,AS FOLLOWS: THE FIRST ONE 10 MIN. LATER . THE SECOND ONE 24 HOURS LATER; THE THIRD ONE 48 HOURS AND THE FOURTH ONE 7 DAYS AFTER SETTING TIME.
