Q1: What makes Deflamer LFR-8007 suitable for PU leather applications specifically?
A: Deflamer LFR-8007 is specially engineered for polyurethane-based leather systems, offering excellent compatibility with PU resins and solvents while maintaining film integrity, flexibility, and surface aesthetics—without compromising flame retardancy performance in thin-film coatings.
Q2: Is Deflamer LFR-8007 truly halogen-free, and what does that mean for end-product compliance?
A: Yes, Deflamer LFR-8007 contains no chlorine, bromine, or other halogenated compounds. This eliminates risks associated with corrosive smoke, dioxin formation during combustion, and regulatory restrictions on halogenated substances in many consumer-facing applications—including automotive interiors and furniture.
Q3: How is Deflamer LFR-8007 typically incorporated into PU leather formulations?
A: It is generally added during the pigment paste or resin mixing stage, prior to coating. Due to its good dispersion characteristics, it integrates smoothly without requiring high-shear processing—though optimal distribution is achieved with standard mechanical agitation compatible with PU production lines.
Q4: Does Deflamer LFR-8007 affect the physical properties of finished PU leather, such as tensile strength or abrasion resistance?
A: When used within recommended dosage ranges, Deflamer LFR-8007 demonstrates minimal impact on key mechanical properties. Formulators commonly observe preserved flexibility, tear strength, and surface durability—provided overall formulation balance (e.g., plasticizer and crosslinker levels) is maintained.
