Polybutylene naphthalate resin (PBN resin)


This is a crystalline resin formed by the polycondensation of NDC(naphthalene dicarboxilic acid) and 1,4-butanediol.
Due to naphthalene skeleton derived from NDC, this resin has the following unique features.

  • Excellent in abrasion property
  • Low elution performance
  • Excellent in chemical resistance
  • Excellent in barrier performance against gas and water vapor
  • Fast in Crystallization speed
