Title:
HIGH THERMAL STABILITY THERMAL CUTOFF DEVICE PELLET COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/033722
Kind Code:
A1
Abstract:
Provided is a pellet composition having enhanced thermal stability for use in a thermally-actuated, current cutoff device. The solid thermal pellet composition comprises an organic compound have low ionization potential, such as dibenzosuberenone. The solid pellet maintains its structural rigidity up to a transition temperature (Tf), but further has improved overshoot temperature ranges. Therefore, the improved thermal pellets have a maximum dielectric capability temperature (Tcap), above which the pellet composition may lose substantial dielectric properties and conducts current that is at least 160°C greater than the Tf. The aging performance is further enhanced. Further, methods of enhanced processing and pelletizing are provided.
