Introduce: Profile: Chriskev Company, Inc. provides monomers for the polymer chemist. We also support production chemists and engineers in reformulating and improving the existing high performance polymers. Our products include dianhydrides, fluorinated diamines, diamines and other monomers. Our dianhydrides include 3,3',4,4'-benzophenone tetracarboxylic dianhydride, pyromellitic dianhydride, 3,3',4,4'-biphenyl tetracarboxylic dianhydride, 2,2'-bis-(3,4-dicarboxyphenyl) hexafluoropropane dianhydride, 4,4'-oxydiphthalic anhydride, 3,3',4,4'- diphenylsulfone tetracarboxylic dianhydride, 4,4'-bisphenol a dianhydride, hydroquinone diphthalic anhydride and ethylene glycol bis. Our diamines are 2,2-bis [4-(4-aminophenoxy)phenyl] propane, 4,4'-methylene dianiline, 4,4'-oxydianiline, 3,4'-oxydianiline, 2,2'-dimethyl-4,4'-diaminobiphenyl, 3,3'-dihydroxy-4,4'-diamino-biphenyl, 3,3'-diaminodiphenyl sulfone, 1,3'-bis (3-aminophenoxy) benzene and o-tolidine sulfone. Our monomers are used to formulate specialized polymers to meet specific needs such as high temperature parts for military jet engines to dental composites and from chip wafer coatings to separation membranes.
