Application of GP-084 cellular silicone rubber may reduce the weight and hardness of facial prostheses / 实用口腔医学杂志

ABSTRACT

Objective: To study the feasibility of sandwich structure made by GP-084 cellular silicone rubber and SY-1 silicone elastomer in preparing facial prostheses. Methods: Samples of SY-1 silicone or GP-084 or sandwich of both were made in the size of 100 cm 2. Sandwich structure was made of SY-1 silicone as the top and bottom lyers of 1 mm in thickness and GP-084 cellular silicone as the middle layer of 23 mm in thickness. The weight density and Shore﹝A﹞hardness of the samples were measured. Results: The weight density (?10 3 kg/m 2) of GP-084, SY-1 silicone rubber and the sandwich structure was 0.411? 0.003, 1.245?0.024 and 0.679? 0.002 respectively(P
