Torch Test Pyrophobic LithiumPrevent 200R (LP200R) at 4 mm. Passive Fire Protection for Batteries.
LithiumPrevent is an exclusive and patented intumescent thermoplastic material that expands with heat, preventing and containing thermal runaways in lithium-ion batteries at the cell and module levels. It can be injection molded or extruded. It can be molded into 3D formats for integrated cell holders, spacers, and between modules.
Torch Test of Pyrophobic LithiumPrevent 200R by thickness: 2, 3 & 4 mm.
LithiumPrevent 200R (LP200R) is our injection molding material focused on providing a solution for lithium-ion battery thermal runaway.
