Products

LEONA™ is Asahi Kasei's family of PA66 (polyamide 66, nylon 66) resins.

PA66 is short for polyamide 66—the chemical name—and also known as nylon 66 . PA66 is engineering plastic featuring excellent heat resistance and mechanical strength. PA 66 is crystalline thermoplastic resin. 

Asahi Kasei is responsible for every step in the manufacturing process for PA66 polymers in house, starting from intermediates such as acrylonitrile, adiponitrile, hexamethylenediamine, and adipic acid. 

We offer a wide range of product grades suitable for many different purposes spanning many industrial sectors—making us both Asia's No. 1 manufacturer* of PA66 resin and the No. 1 manufacturer in the Japanese market*, supplying PA66 resin primarily to Japanese automakers and meeting a broad spectrum of customer needs.

TENAC™/TENAC™-C is Asahi Kasei's family of polyacetal (POM) resins. 

POM stands for polyoxymethylene, the chemical name, but these materials are typically known as polyacetal resins. POM resins are engineering plastics featuring excellent sliding properties (friction and wear characteristics), toughness, and fatigue behavior. POM resins are crystalline thermoplastic resins. 

POM resins come in two varieties: homopolymers（[−CH₂O−]n）consisting solely of chains of formaldehyde monomers, and copolymers（[[−CH₂O−]p/[−CH₂CH₂O−]q]n）containing oxyethylene units formed from trioxane.

In the polyacetal business field, Asahi Kasei is the world's only manufacturer* of both homopolymers (TENAC™) and copolymers (TENAC™ -C) with our own proprietary technology.

XYRON™ is Asahi Kasei's family of modified PPE (modified polyphenylene ether or mPPE) resin products. 

Modified PPE resins are polymer alloys formed by compounding PPE resins with other types of resin. PPE resins are engineering plastics featuring excellent heat resistance, flame retardance, electrical properties, and dimensional stability, with low water absorption and low specific gravity. PPE resins are amorphous thermoplastic resins. 

Asahi Kasei uses 2,6-xylenol as a raw material to produce PPE, and then to form alloys and compounds with other resins to yield an extensive lineup of material grades. For each type of alloy, we offer various grades to meet a diverse range of customer needs, making us Asia's No. 1 manufacturer* of modified PPE resins.
