“…Still, PLA is not well suited on its own as a ame-resistant polymer as it drips under combustion. 7 Therefore, similar to the pathways adopted for engineering plastics, PLA can be customized for ame retardancy among other important aspects such as wear resistance and vapor barrier. For example, the adhesion of the matrix and ller play a critical role when improving abrasive wear performance through compatibilization or surface modications.…”

“…It was proposed that the presence of hyperbranched polymers in PLA/FR composites can improve its mechanical properties. Pursuant to this, the combinatory effect of a derivative hyperbranched polymer containing a triazine group (Figure 9a) and APP with PLA was studied in a mass ratio of 15:5 [117]. Unfortunately, its mechanical properties were not investigated, but the composite had excellent anti-dripping properties, high LOI value (41.2%), and lower PHRR (Figure 9b) compared to other hyperbranched flame retarded PLA composites.…”

PLA has become a commodity polymer with wide applications in a number of fields. However, its high flammability with the tendency to flow in fire has limited its viability as a perfect replacement for the petrochemically-engineered plastics. Traditional flame retardants, which may be incorporated into PLA without severely degrading the mechanical properties, are the organo-halogen compounds. Meanwhile, these compounds tend to bioaccumulate and pose a risk to flora and fauna due to their restricted use. Research into PLA flame retardants has largely focused on organic and inorganic compounds for the past few years. Meanwhile, the renewed interest in the development of environmentally sustainable flame retardants (FRs) for PLA has increased significantly in a bid to maintain the integrity of the polymer. A review on the development of new flame retardants for PLA is presented herein. The focus is on metal oxides, phosphorus-based systems, 2D and 1D nanomaterials, hyperbranched polymers, and their combinations, which have been applied for flame retarding PLA are discussed. The paper also reviews briefly the correlation between FR loadings and efficiency for various FR systems, and their effects on processing and mechanical properties.

“…The formation of the intumescent char layer was due to uniform dispersion of APP after coating on the one hand and the surface treatment agent PCOC acting as the carbon source on the other hand; so the carbon layer presented a typical morphology of the intumescent char layer. It is well known that the char layer can block the transfer of oxygen and heat, which decreased the combustion intensity of materials (Chen et al, 2016;Chen et al, 2017c;Li et al, 2018;Guo et al, 2019;Xu et al, 2019). From Table 4, the char yield of RPUF/MAPP-1000 reached 36.5% at 400 s. The results indicated that MAPP-1000 with a high degree of polymerization was more conducive to promoting the formation of the intumescent char layer with higher thermal stability.…”

Ammonium polyphosphate (APP) with different polymerization degrees were modified by a novel phosphorus-containing organosilicon compound (PCOC), and the products obtained were coded as MAPP-30 and MAPP-1000. Then they were applied to prepare flame-retardant rigid polyurethane foam (RPUF) separately. The impact of modified APP (MAPP) on the flame-retardant properties of RPUF was investigated by the limited oxygen index (LOI) test, horizontal burning test, and cone calorimeter test. The morphologies of the char residues were observed by SEM. Furthermore, the mechanical properties of RPUF composites were measured by the compressive strength test. The results showed that whether the degree of polymerization of MAPP is 30 or 1000, they both had greater charring ability and better flame-retardant properties than unmodified APP. The residual char yield of RPUF/MAPP-30 (37.3%) and RPUF/MAPP-1000 (36.5%) were both significantly higher than RPUF/APP-30 (22.8%) and RPUF/APP-1000 (24.9%). The peak heat release rate value of RPUF/MAPP-30 was 29.9% lower than that of RPUF/APP-30, and the drop of RPUF/MAPP-1000 was 50.9% compared to RPUF/APP-1000. Moreover, the total heat release of RPUF/MAPP-1000 (9.7 MJ/m2) was much lower than that of RPUF/MAPP-30 (11.3 MJ/m2). In summary, MAPP-1000 has the best flame-retardant properties among all RPUF composites. In addition, the results also showed that flame-retardant performance and the mechanical properties dramatically decreased with the increase in the addition of MAPP-1000, and the RPUF composite had the best comprehensive performance with 20% content of MAPP-1000.
