Flame Retardant Properties

Polymer materials are ubiquitous in daily life. While polymers are often convenient and helpful, their properties often obscure the fire hazards they may pose. Therefore, it is of great significance in terms of safety to study the flame retardant properties of polymers while still maintaining their optimal performance. Current literature shows that although traditional flame retardants can satisfy the requirements of polymer flame retardancy, due to increases in product requirements in industry, including requirements for durability, mechanical properties, and environmental friendliness, it is imperative to develop a new generation of flame retardants. In recent years, the preparation of modified two-dimensional nanomaterials as flame retardants has attracted wide attention in the field. Due to their unique layered structures, two-dimensional nanomaterials can generally improve the mechanical properties of polymers via uniform dispersion, and they can form effective physical barriers in a matrix to improve the thermal stability of polymers. For polymer applications in specialized fields, different two-dimensional nanomaterials have potential conductivity, high thermal conductivity, catalytic activity, and antiultraviolet abilities, which can meet the flame retardant requirements of polymers and allow their use in specific applications. In this review, the current research status of two-dimensional nanomaterials as flame retardants is discussed, as well as a mechanism of how they can be applied for reducing the flammability of polymers.

Abstract A thorough study was carried out to investigate the priority of a novel co-rotating non-twin screw extruder (NTSE) over a traditional twin screw extruder (TSE) in the mixing process of halogen-free intumescent flame-retardant acrylonitrile-butadiene-styrene (ABS) composites. The homogeneity of the flame-retardant additives of the composites processed by NTSE and TSE under the same operating conditions was characterized by using mechanical performance properties, limiting oxygen index values, UL-94 tests, and thermogravimetric analysis. All the results suggested that NTSE could achieve better mixing of the flame-retardant additives in the polymer matrix than TSE, which was further clarified by the scanning electron microscope pictures.

Thermal Stability Of

Bis(2-hydroxyethyl) terephthalate (BHET) obtained from waste poly(ethylene terephthalate) bottles was used to synthesize polyurethane foams (B-PUF) and the fireproof B-PUF in the presence of nonhalogen flame retardant, namely, aluminum hydrogen phosphonate (AHP). Loading of 25 php AHP was needed for B-PUF/AHP to achieve UL-94 V-0 rating. The thermal stability of B-PUF was improved with the addition of AHP through the thermogravimetric analysis (TGA) results. In addition, other properties such as density and foam structure were also investigated. The outcomes of this study also confirmed that the B-PUF prepared from recycled PET not only were composed of a high percentage of waste poly(ethylene terephthalate), which could help reduce the amount of recycled polymer materials and improved waste management but also met the high demands for the fire safety of polymer applications.

This paper discusses the prospective flame retardant systems for polymeric materials, while considering the environmental issues they create. Polymer nanocomposites with carbon nano-additives and layered silicates are presented as a new type of flame retardant system which exhibits a synergistic effect flame retardancy for traditional polymer thermoplasts. Particular attention is paid to the novel intumescent flame retardants based on the oxidized renewable raw materials, which can be successfully used in the manufacture of multi-purpose timber construction and polymer materials.

The Impact

Polypropylene (PP) and polyamide (PA) polymers are used in different situations where they provide a flame retarding effect to meet safety standards. The expandable graphite as an additive for polymer materials has a good flame retardant effect and it does not harm the environment. The processing of this additive is presented for those two different polymers. Compounds with proportions of 10, 20, 30% of this additive were prepared in order to investigate the processability and flame retarding effect of PP and PA samples. The results show that the process conditions differ greatly between the polymers used in higher proportions. The improvement of the flame retarding effect was observed for both polymer compounds with expandable graphite. The plastics flammability standard UL 94 V0 could be achieved for the PP compound in all additive proportions and for the PA compounds only above 20%. The processing of the PP compound with co-rotating twin-screw extruder and an injection moulding machine takes place works well and provides a good homogenous mixture. The PA compound could not be processed at a higher additive content by the extruder. Special screw configuration is necessary to process this polymer compound. Also the flame retardant effect was inferior to the PP compound. The mechanical properties of the compounds decrease with the increasing additive content, particularly the impact strength of the samples.
