Flame Retardant Resin Solutions
Self-extinguishing unsaturated polyester resin for fire-rated materials in construction, transportation, and electrical industries. UL94 V-0 capable grades formulated for SMC/BMC, pultrusion, and compression molding processes.
Product Overview
Flame retardant unsaturated polyester resin is specially formulated to self-extinguish and limit smoke generation when exposed to fire. These resins are the preferred matrix for fire-rated composite components in building infrastructure, mass transit interiors, electrical enclosures, and marine applications. Aertuo's 27-series FR resins deliver consistent UL94 V-0 performance with excellent mechanical retention and processing latitude.
Common Challenges
Inconsistent UL94 V-0 classification across production batches due to uneven flame retardant dispersion
Excessive smoke density and toxic gas generation during combustion limits use in enclosed spaces
Mechanical degradation caused by high loading of flame retardant fillers reduces part durability
Difficulty maintaining minimum oxygen index (OI ≥ 28%) while preserving processability and surface finish
Our Solution
Aertuo's 27-series flame retardant resin range delivers reliable fire performance without compromising mechanical properties. The 27-81A grade achieves an oxygen index of 28%+ with UL94 V-0 at 1.6 mm, while 27-91H offers enhanced heat resistance for high-temperature molding applications. Low-smoke variants are available for mass transit and building interior applications where smoke toxicity is critical. All formulations maintain excellent wet-out and flow characteristics for SMC/BMC and pultrusion processes.
