Furthermore, the viscosity index and for some applications also the Silicone oil is a liquid based siloxane that is part of the methyl silicone fluid system. Increasing the extensional viscosity is one way to reduce emulsification. Adding 8% oil is seen by many people to be an adequate reduction of the hardness (about 3-5 shore points) and is recommended. Features & Benefits. Within the silicone oils, the polymeric chains, which have a very high methyl density and thus low intermolecular association, glide and slip over one another: the oils are fluids. 3970 to 1. High-viscosity (5000 centistokes) polydi­ methylsiloxane oil, which was used in our study, is currently favored because of its greater chem­ ical stability (7). The hallmark properties of silicones – unusually low viscosity at high molecular weight and very low interfacial tensions – characterize Momentive’s basic fluids and help lead to benefits such as low-temperature fluidity, excellent lubricity, high surface activity and remarkable spreading or penetration.
