A pasting carrier for a lead-acid battery. The pasting carrier includes a nonwoven fiber mat having a thickness between 5 and 50 mils, the nonwoven fiber mat being composed of a plurality of entangled glass microfibers.

Acid battery pasting carrier

A carpet tile includes a textile top member and a cushion mat that is coupled with the textile top member via a thermoplastic material. The textile top member includes carpet yarns and a backing that is coupled with the carpet yarns so that the backing structurally supports the carpet yarns. The cushion mat includes a polymeric material component having polymer fibers that are randomly oriented and entangled together and a scrim reinforcement that is disposed within the polymeric material component. The scrim reinforcement reinforces and stabilizes the polymeric material component and is entirely covered and concealed by the intermeshed polymer fibers.

Scrim-reinforced cushion mat for carpet tiles

A carpet tile includes a textile top member and a carrier mat that is coupled with the textile top member via a thermoplastic material. The textile top member includes carpet yarns and a backing that is coupled with the carpet yarns so that the backing structurally supports the carpet yarns. The carrier mat includes a polymeric material component, a reinforcement, and a binder that is uniformly distributed throughout the polymeric material component and reinforcement component. The polymeric material component includes polymer fibers that are randomly oriented and entangled together. The reinforcement is disposed within the polymeric material component so that the reinforcement is entirely covered and concealed by the entangled polymer fibers to prevent exposure to a user. The reinforcement mechanically reinforces and stabilizes the polymeric material component and carpet tile.

Reinforced polymeric nonwoven mat for carpet tiles

A battery separator for a lithium-ion battery includes a nonwoven fiber mat that is composed of entangled microfibers having an average fiber diameter of less than 6 microns. The nonwoven fiber mat also includes a binder that binds the microfibers together and a polymer component that is dispersed homogeneously through or within the entangled microfibers so that the polymer component is uniformly distributed throughout the nonwoven fiber mat and so that the entangled microfibers, the binder, and the polymer component form a single layer component or product. The polymer component is configured to melt within the nonwoven fiber mat when exposed to a sufficiently high heat in order to effectively interrupt an electro-chemical process of the lithium-ion battery and thereby prevent overheating of the lithium-ion battery. The nonwoven fiber mat is typically between 0.1 and 20 mils thick.
