Häufig gestellte Fragen
Answers prepared from the existing XUYE category information and common buyer questions.
What is the appliance of SIPM?
SIPM (Dimethyl-5-Sulfoisophthalate Sodium Salt) is mainly used in polyester, film and other aspects. Among them, polyester is the main application field, mainly as the third monomer of cationic modified polyester CDP. Because CDP fibers contain sulfonic acid groups, they have good affinity for cationic dyes. The dyed fibers are bright in color, complete in chromatography, and can be dyed deeply. The modified fibers have a hairy feel and are easy to blend with wool, which is suitable for fabrics for men's and women's clothing in winter.
What is the appliance of 5-SSIPA?
5-SSIPA is widely used in polyester fibers, coatings, dyes and resins and other fields. Its main role is as a copolymerization modifier, which can significantly improve the hydrophilicity and dyeing properties of polyester materials. Since 5-SSIPA contains sulfonic acid groups, adding it to polyester fibers can make the fibers more easily absorb moisture and improve their comfort. 5-SSIPA can act as a dispersant in the polymerization reaction, which helps to improve the uniformity and stability of the product.
What is Dimethyl-5-Sulfoisophthalate Sodium Salt?
It is a white crystalline chemical compound, mainly used as a hydrophilic additive or intermediate in industrial production, helping to improve the water-related properties of target products.
Is Dimethyl-5-Sulfoisophthalate Sodium Salt easy to use in production?
Yes, it has good water solubility and can be directly mixed with other raw materials in production. It works stably under normal industrial reaction conditions without complex operation requirements.
