Japanese Patent JP7259014
Kind Code:
B2
Abstract:
A fire protection article is provided that includes a fire barrier comprising a plurality of non-combustible fibers, and a passive thermal insulator coupled to the fire barrier and comprising a plurality of non-meltable fibers. Optionally, the fire protection article displays a time to break in the 1100° C. Break Strength Test of at least 10 seconds or a minimum tensile strength at 150° C. of at least 5 kPa. Optionally, the fire barrier comprises substantially continuous fibers that are mutually entangled. The fire barrier and passive thermal insulator can be mutually secured using a suitable polymeric binder, such a thermoplastic fluoropolymer binder. The combination of a relatively thin fire barrier with a comparatively thicker passive thermal insulator can provide thermal runaway protection in lithium-ion battery applications, structural integrity and a high degree of thermal insulation in the event of fire exposure.
