Note
  • Take care to ensure that Xyron is not predried for longer than 8 hours. Excessive predrying may result in degradation of physical properties and color changes.
  • Properly molded Xyron (sprues, runners, molded articles, etc.) may be reground, dried, and remolded without adverse effects. It is essential that material to be reground be free from oil, grease, dirt, and foreign substances, and shows no signs of degradation. Regrind levels up to 20% can be used successfully, but it is not advisable to use reground material for applications where surface appearances are critical.
  • High viscosity GPPS and Asaclean SA™ (available from Asahi Kasei Corporation and distributors) are recommended purging materials for all Xyron grades. Purging should be performed at temperature ranges appropriate for each grade.
  • In order to prevent polymer degradation when molding operation is stopped or interrupted, the following measures are recommended.
    Up to 30 minutes: Maintain cylinder temperature. Purge barrel using same material prior to the re-start of molding operation.
    From 30 minutes

    to 12 hours:
    Decrease cylinder temperature to 200・20°C. Purge barrel using high viscosity GPPS. Upon commencement of molding operation, Purge barrel using material for molding after increasing cylinder temperature to the required level.
    For downtime longer than 12 hours: Purge barrel with high viscosity GPPS, and shut down machine.
  • Generally, mold release agents are not required for molding Xyron resins. In cases where mold release agents are needed due to the complex shape of the mold, minimal use is recommended. Silicone-based mold release agents such as Pelicoat B™ (manufactured and sold by Chyukyo Kasei Kogyo Ltd., Japan) are recommended, as the chemical ingredients do not react with Xyron.

TENAC™

Asahi Kasei started the production and sales of TENAC™ homopolymers in 1972, followed by copolymers in 1985, and the world-first polyacetal block copolymers TENAC™ LA series in 1987.
The company started production and sales of copolymers in Zhangjiagang, China since 2004 in addition to the plant in Japan.
In the polyacetal business field, Asahi Kasei is the world's only manufacturer of both homopolymers (TENAC™) and copolymers (TENAC™ -C), as well as for the block copolymers "TENAC™ LA series" with its own unique technologies.

LEONA™

The Asahi Kasei LEONA™ grades are molding compounds based on PA66, PA612 and semi-aromatic polyamides such as PA66/6I. The range is available in unfilled grades as well as reinforced with glass fibers and special composites. LEONA™ is noted for its high strength, heat, oil, and abrasion resistance as well as for its processability.

Asahi kasei has long experience on the polyamide market since 1972, and is fully able to produce PA66 completely from monomer to compound. Our compounding technologies allow for global quality with local production.

XYRON™

Asahi Kasei started the production and sales of XYRON™ in March 1979. XYRON™ consists of various portfolio that enables the selection of various PPE alloy combinations with other resins such as polystyrene (PS), polyamide (PA), polypropylene (PP), polyphenylene sulfide (PPS) .
