• Product description :

  Sodium Dimethyl Isophthalate-5-Sulfonate General Chemical name Third Monomer (SIPM) Structural formula Specification Appearance: White powder without visible impurities Acid value(mgKOH/G): ≤0.3 Saponification value(mgKOH/G): 378±2 Sulfate ion(ppm): ≤100 Water(wt%): ≤0.3 Ferrum(ppm): ≤ 4 Absorbance(ABS): ≤ 0.05 Chloride ion(ppm): ≤ 8 Use: Mainly applied to polyester and film and so on. It is use as third monomer for Cationic modified polyester CDP. The modified polyester CDP has excellent affinity with cationic dyes, which promote dyeing property greatly, so the fabric looks fresh and bright and feels soft and woolly-aspect. SIPM is the most widely used modifier for polyester dyeing. Package: It is packed in 25Kgs woven bag lining with kraft paper, or according to client’t requirement.
