In this study, the possibility of foaming liquid silicone rubber (LSR) was investigated. The foam was produced by injection molding with two different thermoplastic, expandable microspheres. Different properties were tested using the S2-tensile bar, e.g. density, tensile strength, specific tensile strength, elongation at break, stress at 100 % strain and the hardness. It was found that the two types of microspheres used have similar effects on density, specific tensile strength and elongation at break, but differ in hardness and stress at 100 % strain.
