An intumescent mesh comprises a mesh structure woven from strands that define openings in the mesh structure, the strands being made from non-metal materials. An intumescent material is applied to the strands, the intumescent material being carried such that, in an inactivated state the intumescent material permits airflow through the openings in the mesh structure, and in an activated state, the intumescent material swells and restricts airflow through the openings in the mesh structure. The intumescent mesh is able to withstand a temperature of at least 980° C. for at least 10 minutes prior to failure.

A non-woven fiber mat for lead-acid batteries is provided. The non-woven fiber mat includes glass fibers coated with a sizing composition, a binder composition, and organic active compounds, wherein the organic active compounds are effective in reducing or preventing sulphation in lead-acid batteries.

A cord of a toothed belt is made of a twisted yarn including a band-like material. The band-like material includes a filament bundle of high-strength glass fibers integrated together through a binder. The binder contains a rubber component, at least either a maleimide-based compound or a polyisocyanate compound, and a powdery inorganic filler. A surface of a reinforcing fabric facing opposite to the toothed belt body is coated with a surface-coating rubber layer made of a rubber composition containing a rubber component including hydrogenated nitrile-butadiene rubber as a main part.

Heat resistant separation fabric consisting out of yarns, wherein the yarns comprise metal fibers; wherein the heat resistant fabric comprises boron nitride particles distributed throughout the complete thickness of the fabric; wherein boron nitride particles are present between metal fibers in the yarns; wherein the amount of the boron nitride particles present on the surface of the fabric is not more than the amount of the boron nitride particles present in the bulk of the fabric.
