“…Nilai hasil uji flammability pelat komposit PolyAl-fiber berkisar pada nilai 3,0-3,2 cm/menit. Fenomena ini serupa dengan hasil penelitian Obidiegwu (2012), bahwa semain banyak serat yang ditambahkan maka semakin kecil nilai flammability dari komposit. Hal ini kemungkinan disebabkan oleh adanya kandungan oksigen, nitrogen dan abu dalam serat yang dapat menyebabkan penurunan nilai heating dan flammability.…”

Dalam rangka penanggulangan limbah karton bekas minuman (KBM), telah dikembangkan proses daur ulang untuk mengembalikannya menjadi bahan baku. Tujuan penelitian ini adalah untuk mengetahui potensi pemanfaatan KBM sebagai bahan baku komposit yang lebih tahan air, dan membandingkannya dengan spesifikasi teknis produk sejenis. Pembuatan komposit dilakukan dengan pemanasan menggunakan alat hot press pada suhu 165oC dan tekanan 25-30 kg/cm2 selama 10 menit. Produk komposit yang diperoleh memiliki nilai bending strength 12,78 MPa, bending modulus 11,60 GPa, flammability 3 cm/menit, daya serap air 2,1-14,1%, kadar air 0,9-1,9%, dan rapat massa 0,68-0,94 g/cm3, pada ketebalan 2,5-3,5 mm. Komposit PolyAl-fiber dapat memenuhi persyaratan standar papan serat, papan partikel maupun komposit kayu plastik tanpa penambahan bahan maupun proses lain, yang mengindikasikan komposit PolyAl-fiber memiliki potensi untuk digunakan dalam berbagai keperluan sejenis. Komposit PolyAl-fiber akan dapat menghasilkan papan komposit dengan kualitas lebih baik, karena lebih fleksibel, lebih tahan air, dan lebih tahan api bila dibandingkan dengan produk lain yang terbuat dari bahan baku kayu atau biomassa.Potential of Used Beverages Cartons for PolyAl-Fiber Composite AbstractVarious recycling processes have been developed to overcome the problem of used beverage carton (UBC) waste. Research was conducted to determine the potential utilization of UBC as a material for more waterproof composite and compared it to similar products. The composites were made using hot press machine at temperature of 165oC and pressure of 25-30 kg/cm2 for 10 minutes with 5% - 30% fiber content. The PolyAl-fiber composite obtained had bending strength of 12.78 MPa, bending modulus of 11.60 GPa, flammability of 3 cm/min, water absorption of 2.1-14.1%, moisture content of 0.9-1.9%, and density of 0.68-0.94 g/cm3, at thickness of 2.5-3.5 mm. The PolyAl-fiber composite could meet the requirements for fiberboard, particleboard, or plastic wood composite standards without extra additives or treatment to the raw materials, indicating that it could be used for similar purposes. The PolyAl-fiber composites may able to produce a better quality of composite boards, due to their flexible, waterproof, and fire-resistant characteristics compared to similar products made from wood or

“…Therefore, many flame retardants have been developed [13]. Basing on the knowledge that the glow time of pure PE-LD lasts 18 s, burning time is 50 s and flame propagation rate is equal to 257 s, whereas in the filled PE-LD those combustion processes occur with retardancy increased even by 100-600 % [14,15], the flame test has been performed. There are many test methods to examine the flammability of a polymer.…”

Fly ash used as a reinforcing and flame-retardant filler in low-density polyethylene

In this study, the possibility to modify low density polyethylene (PE-LD) with fly ash (FA) was tested. Four series of PE-LD composites filled with 1, 5, 20 or 50 wt % of FA were prepared by injection molding. The samples in each of the series differed in particle size of the filler used (0-15 µm, 15-30 µm, 30-60 µm). The influence of amount and the particles size of filler on morphology, mechanical properties, thermal stability and flammability of the composites were investigated. The results show that composites with the addition of FA in the amount up to 20 wt % are characterized by good mechanical properties and processability, and also smaller than the pure PE-LD, flammability.

“…LDPE constitutes one of the largest single market segments of commodity thermoplastics worldwide owing to its low cost of production and excellent processing performance at relatively low temperatures, typically around 110 o C. [25] However, its extremely poor native FR properties and bulk flammability have necessitated the use of FR additives in many commercial applications. [26][27][28] Together, LDPE's exceptionally high commercial popularity, low melt-processing threshold, and poor FR performance make it an excellent model substrate for potential new FR additives. Here, the FR performance of DNA is compared to that of melamine polyphosphate (MPP).…”

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
