Silicone is considered the "gold standard" among elastomers. Liquid Silicone Rubber is one of our primary materials, particularly in the field of medical simulation. It boasts excellent biocompatibility, is non-toxic and odorless, and exhibits outstanding resistance to both extreme temperatures and chemical corrosion. Furthermore, its hardness can be flexibly adjusted to simulate the soft, tactile feel of skin and soft tissues; concurrently, it possesses exceptional tear strength and resists aging or deformation even after prolonged use.
Main components: Polydimethylsiloxane (PDMS), Si-O-Si backbone
