| Application: | PDMS can be used as a precursor in the synthesis of poly(dimethylsiloxane-ure PDMS is a material of choice for ophthalmic applications due to its high mechanical strength, transparency, and oxygen permeability. It can be used as a prepolymer to prepare a glucose permeable interpenetrating network of PDMS and poly (N-isopropyl acrylamide (PNIPAAM). These networks can be used in ophthalmic applications. PDMS can also be used to synthesize fire and heat-resistant polyurethane-PDMS hybrids. The addition of PDMS provides low flammability and thermal stabilization to polyurethane under pyrolytic conditions. PDMS is used as an additive to prepare TEOS-based stone protective hybrid crack-free xerogels. The addition of PDMS accelerates the gelling process and helps to achieve effective stone protection. |
