Abstract
Aims: Evaluate some mechanical and physical properties of Acrylic-based soft- liner modified with two types of plasticisers by adding plasticisers Di-2-ethylhexyl phthalate (DEHP) and glycerol in two distinct weight percentages (2% and 5%).Materials and Methods: a Total of 90samples were prepared ,45 specimens for tensile strength test with a Dumbbell-shaped specimens and a central cross- sectional area of (25 × 4 × 2 mm) were produced by an acrylic-based soft liner(EZ- soft liner, Korea) divided into 5 groups according to the amount of plasticiser added, and 45 specimens were prepared for water sorption , with the a dimension of( 10 diameter x 5mm thickness) and divided into 5 group also according to the amount of plasticiser added. The anaylsis of sorption was based on the intial dry weight and on the wet and dry weight after immersion. Software for statistics was used to examine the data (SPSS).Results:In comparison to the other groups, the groups that were changed by plasticisers exhibited a considerable decrease in tensile strength for both materials. Sorption was higher in the group C and D than in the control group.
