Flame Retardant Fabrics for Fire Curtains and Fire Containment Systems

Z-Block™ flame retardant fabrics are high temperature polymer coated fiberglass fabrics treated with a proprietary formulation of fire retardants and finished with a high temperature silicone overcoat (SOC). Z-Block™ offers exceptional resistance to fire, smoke, abrasion, UV, and adverse weather. Z-Block™ is formulated with inorganic materials and will not produce hazardous outgassing.

This heat resistant fabric is designed for use in fire curtains, fire containment covers, and custom smoke and fire protection systems. When exposed to flame in these applications, the coating develops a protective high temperature silica layer that prevents flame penetration at temperatures up to 1800°F / 980°C.

Z-Block™ is also an excellent insulation jacketing material for multi-layer insulation blankets, but it is not intended for hot-side applications where contact temperatures exceed 350°F / 175°C. 

The Z-Block™ coating can also be applied to some of Newtex’s Zetex® Steel Wire Reinforced Fabrics. These fabrics are woven with stainless steel wire to create a stronger flame retardant fabric with superior abrasion and puncture resistance. Wire reinforced Z-Block™ is ideal for fabricating insulation covers such as blankets and other jacketing that will be subject to vibration, abrasion, or repetitive movement.

Some Z-Block fabrics can be modified for Berry Amendment compliance. Please notify our sales team if you require Berry-compliant materials.
