Poly[oxy(phenylphosphinylidene)oxy-1,4-phenylenesulfonyl-1,4-phenylene] NEW

Product Introduction PSPPP is an additive type halogen-free flame retardant, which is a broad-spectrum halogen-free flame retardant. It can be used as the main flame retardant in spinning grade PET, with a dosage of 4-7% to meet the requirements. It can also be used as an auxiliary or main flame retardant in other plastics such as PMMA, PBT, PA, TPU, PC, ABS, PP, PE, etc. It has high flame retardant performance and a wide range of applications. In addition, due to the presence of sulfur in the structure, the corrosion resistance of the polymer is improved. Quality standard: Testing project unit indicators Appearance white or gray white particles main content% 99.0 melting point ℃ 155-180 decomposition temperature 350 moisture 0.5 solubility insoluble in water Testing project unit indicators Appearance white or gray white particles main content% ≥ 99.0 melting point 155-180 ℃ decomposition temperature ℃ 350 moisture% ≤ 0.5 solubility insoluble in water Main uses: PSPPP is a broad-spectrum halogen-free flame retardant that can be used as the main flame retardant in spinning grade PET, with a dosage of 5% meeting the requirements. It can be used as an auxiliary or main flame retardant in other plastics such as PBT, PA, TPU, PC, ABS, PP, PE, etc. It has high flame retardant performance and a wide range of applications. In addition, due to the presence of sulfur in the structure, the corrosion resistance of the polymer is improved. It is recommended to add 4.5%~5% PSPPP to PET to achieve UL94-V0 grade (3.2mm). Storage and precautions: Store in a dry, room temperature environment to prevent moisture and heat. Packaging 25kg/bag, paper plastic+inner lining+aluminum foil packaging.
