Low viscosity elastomers provide a flowable silicone that can be used to encapsulate a device or be low-pressure molded into a part. NuSil low viscosity elastomers offer an alternative to HCRs and LSRs with other unique properties.


Low viscosity elastomers are particularly useful for applications and manufacturing processes that are most efficient using a pourable, self-leveling silicone. Applications include encapsulating a device, backfilling a void and potting an electronic component.

Key properties and considerations

‒ Flowable and self-leveling

‒ Easy to process

‒ Adjustable cure schedule: low- and high-temperature cure

‒ Many optically clear options
