Name:DIMETHYL-5-SULFOISOPHTHALATE SODIUM SALT(SIPM,DMSIP) Introduction: Physical and chemical Property: Molecular Formula: C10H9O7SNa Molecular Weight: 296.23 Cas No.:3965-55-7 SIPM is mainly used in producing Dacron, film, etc., especially in the field of Dacron as the third monomer of cationic dyeable polyester(CDP). It has good affinity fuction with cation dyestuff because of the CDP fibre containing sulfo group, the dyed fibre is bright and lustrous, having a complete range of color and dying deeply, so this kind of fibre is developing quickly at abroad. The output of modified polyester fibre of amounts to more than 15%. The modified fibre has woolens feeling, it is easily blended with fleece and suitable for materials for making garments.

DIMETHYL-5-SULFOISOPHTHALATE SODIUM SALT(SIPM,DMSIP) Synonyms: Dimethyl-5-Sulfoisophthalate Sodium Salt; 1,3 Benzene-Dicarboxylic Acid; 5 Sulfo-1,3-Dimethyl Ester Sodium Salt; DMS; SIPM; DMSIP. CAS Registry Number CAS RNo. is: 3965-55-7 Formula Chemical formula is: C10H9O7SNa Molecular Weight MW is: 296.24 g/mol. To be used for SIPM is mainly used to produce the dyed polyester chip. It is also used in water dispersible resin systems applied in coating and adhesives. It is acting as the third monomer of cation modified polyester (CDPET). It has a good affinity function with cation dyestuff because of the CDPET fiber containing sulfo group, the dyed fiber is bright and lustrous, having a complete range of color and dying deeply. The modified fiber has woolens feeling, it is easily blended with fleece that is necessary for garments manufacturing.
