Some physical properties of an improved facial elastomer: a comparative study.

An attempt was made to evaluate some properties of clinical importance of a new facial elastomer, Cosmesil HC2. A comparative study versus Silskin II and Cosmesil SM4 was also carried out and took into account the effect of weathering after exposure to ultraviolet radiation. The results showed that Cosmesil HC2 is a resilient material and yet displays good tensile characteristics. The results also showed that weathering does not significantly affect Cosmesil HC2 elastomer's tear strength. The overall effect of irradiation was moderate in all materials tested.
