Low viscosity elastomers
NuSil® low viscosity elastomers from Avantor® are flowable silicones that are ideal for low-pressure molding processes, as well as providing an effective material for encapsulating devices such as electronics.
The NuSil line of low viscosity elastomers (LVEs) are ideal for molding or casting a part, as well as encapsulating components in a device. They also offer a lower viscosity alternative to HCRs and LSRs for parts production.
NuSil LVEs are typically two-part, platinum-catalyzed, addition cured silicones that can be designed with an adjustable cure schedule to accommodate both low- and high-temperature curing. Because LVEs are flowable and self-leveling, they can be poured directly into molds or forms and can also be low-pressure molded into parts.
NuSil low viscosity elastomers are available in many optically clear options and can be supplied in convenient cartridges that allow for direct application into molds or forms for potting, eliminating the need for separate mixing and de-airing steps.
