Polybutylene Naphthalate (PBN) resin
PBN Resin is TEIJIN's polyester-based engineering plastic developed through its own technology, positioned apart from PBT through slidability, chemical resistance, barrier properties and wear-focused performance.
PBN is presented as a crystalline resin based on NDC and 1,4-butanediol, with the official page framed largely through comparison against PBT.That makes it especially practical for replacement or differentiation studies rather than for a generic one-family review.
TEIJIN emphasizes slidability, chemical resistance, and gas and vapor barrier characteristics as core features.This suggests a family position for parts where wear, sliding behavior and barrier performance matter more than a simple stiffness comparison.
The engineering section directly shows abrasion and chemical-resistance data, making the page a useful starting point for wear-critical application review.PBN is best explained through PBT replacement logic, wear performance and chemical durability.
