The aim of this study was to assess effect of various beverages on mechanical properties of thermoplastic materials.
180 thermoplastic samples of three different components (Group I- Hardcast, Group II- Duran, Group III- Bioplast) were thermoformed and were divided into 5 subgroups according to the type of beverage used (Subgroup a- Artificial saliva, Subgroup b- Carbonated drink, Subgroup c- Coffee, Subgroup d- Green tea, Subgroup e- Energy drink). All the samples were immersed for 10 minutes everyday for 2 weeks and air dried for the testing of their mechanical properties (Yield strength, elongation and elastic modulus) with the help of Servo Controlled Dynamic Universal Testing Machine.
All the above-mentioned thermoplastic materials tested showed an insignificant (
