“…[6] The foamy char built by these intumescence flame retardants increased the distance between flame and polymer and reduced flame development as well as smoke production. [8,9] Divers efforts to improve the combustion properties of CA by flame retardants were undertaken and are currently under investigation. [10,11] For instance, ammonium phosphates have shown promising effects in combination with CA.…”

The combustion properties of natural DNA mixed with the nature-derived thermoplastic cellulose acetate (CA) were determined. The flame retarding properties of DNA in mixtures with CA were significant and concentration dependent, the higher the DNA content the better the flame retardation. Ammonia was detected during the heating of CA-DNA mixtures. In contrast, carbon monoxide (CO) formation was distinctly reduced during combustion of the CA mixtures with DNA when compared with pure CA. Thus, DNA can be considered as a natural and re-growing polymeric flameretardant for versatile applications of CA-based thermoplastic polymers in order to form eco-friendly polymer mixtures.

“…Finally, studies have shown that effective char formers such as intumescent FR agents also tend to reduce smoke production, as many volatile products of degradation are retained more readily in the char. [13] The use of deoxyribonucleic acid (DNA) was recently described as a coating for textile and polyurethane foam applications. [14][15][16][17][18] Much like APP and MPP, DNA is rich in both phosphate and nitrogen.…”

Deoxyribonucleic acid (DNA) was investigated as a flame retardant (FR) additive for melt-compounded formulations with low-density polyethylene (LDPE) and compared to LDPE compounded with melamine polyphosphate (MPP), one of the industry standard intumescent FR additives for plastics. DNA showed a much greater compatibility with the LDPE matrix than MPP. At high loading levels, DNA showed minimal increases in compounding torque, while MPP increased torque by over 20%. Qualitative evaluation using SEM and EDS showed that DNA/LDPE blends had significantly improved crosssectional morphology, with fewer microaggregates and improved particle dispersion than MPP/LDPE. Horizontal burn testing showed that DNA markedly reduced flame burn distances in LDPE above loading levels of 5% w/w. Biochemical characterization of heat-treated DNA revealed that DNA undergoes denaturation, fragmentation, and
