The flame retardant mechanism of magnesium hydroxide sulfate whiskers(MHSH) is analysed and MHSH and magnesium hydroxide are used to fill high-density polyethylene(HDPE) respectively. The mechanical and flame resistance properties of composite material (HDPE) were also studied in this paper contrastively. The tensile strength and elongation of the compound are increased 2.5% and 36% severally, while MHSH content in weight reaches 20%;at the same time, the oxygen index (OI) of composite materials varies from 17 to 24.2. In contrast, the tensile strength and elongation of the HDPE/ Mg(OH)2compound are decreased 6.4% and 48% respectively, OI being 19.6. To sum up, the results of tensile and flame tests of compound material showed the HDPE containing as-prepared whiskers had better overall properties，exceeding that of Mg(OH)2.

Resultant Data

Gangue as flame retardant was used to PVC, the mechanical properties and flame retardance of the samples were studied. The resultant data show that gangue little effect on the mechanical properties of the sample, especially tensile strength, yield stress, and 10% of gangue obtained good flame retardance. PVC treated with flame-retardants showed a high limiting oxygen index, char yield, which indicated that the flame retardance of the treated PVC was improved.

This paper aims to study the surface morphology, flammability and tensile properties of sugar palm fiber (SPF) hybrid with polyester (PET) yarn-reinforced epoxy composite with the addition of magnesium hydroxide (Mg(OH)2) as a flame retardant. The composites were prepared by hybridized epoxy and Mg(OH)2/PET with different amounts of SPF contents (0%, 20%, 35% and 50%) using the cold press method. Then these composites were tested by horizontal burning analysis, tensile strength testing and scanning electron microscopy (SEM) analysis. The specimen with 35% SPF (Epoxy/PET/SPF-35) with the incorporation of Mg(OH)2 as a flame retardant showed the lowest burning rate of 13.25 mm/min. The flame took a longer time to propagate along with the Epoxy/PET/SPF-35 specimen and at the same time producing char. Epoxy/PET/SPF-35 also had the highest tensile strength of 9.69 MPa. Tensile properties of the SPF hybrid with PET yarn (SPF/PET)-reinforced epoxy composite was decreased at 50% SPF content due to the lack of interfacial bonding between the fibers and matrix. Surface morphology analysis through SEM showed uniform distribution of the SPF and matrix with less adhesion, which increased the flammability and reduced the tensile properties of the hybrid polymeric composites. These composites have potential to be utilized in various applications, such as automotive components, building materials and in the aerospace industry.
