These data are based on the documents, information and data now available and may be changed when new knowledge or information is acquired. For the most current information, call Asahi Kasei Corporation at +81-44-271-2417 or by facsimile at +81-44-271-2166.

Safe Handling

The following is an essential guideline to the safe handling of Leona, as supplied. Always follow this guideline when handling Leona. Please read the relevant material safety data sheet (available from Asahi Kasei Corporation) thoroughly before use. Various additives etc. used in combination with Leona have their own safe use profile and must be investigated separately.

Health and safety

Avoid contact with skin and eyes when gases are generated in the drying and melting of the resin. Do not breathe the above gases. Do not touch hot resin . Local ventilation and wearing of chemical resistant gloves, chemical safety goggles, etc. are necessary when the resin is dried and melted. In case of emergency, call one of the following:

US: +1-800-424-9300 (Chemtrec)
EU: +32-(0)-1458-4545 (BIG v.z.w.)
Japan: +81-44-271-2417 (Asahi Kasei)

Combustibility

Warning: Leona is flammable . Keep away from heat, sparks, and flame when handling or storing Leona. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water or foam extinguishants as extinguishing media.

Disposal

Burn in a properly equipped incinerator or landfill in compliance with all applicable laws and regulations (contact local or state environmental agency for specific rules). During incineration, irritating and highly toxic gases may be generated. Do not dump into sewers, onto the ground, or into any body of water .

Storing

To prevent moisture absorption, do not break the bag seal until just before use. Avoid bag breakage and keep product away from water. Do not return any spilled pellets to the bag.

Molding

Always process Leona under the recommended temperature range. Lower temperatures may lead to local degradation in properties due to nonuniform plasticization, while higher temperatures tend to cause silver streaking, other appearance problems, and resin decomposition. As the optimum temperature range varies among grades, read the guideline for each grade (available from Asahi Kasei). Ensure adequate local or general ventilation throughout molding operation. Detention of Leona in a non-operating, heated cylinder may cause resin decomposition. Before any extended suspension of molding operation, purge and charge the cylinder with non-colored polyethylene or a purging material designed for polyamide resins. Promptly remove and discard any spilled pellets from the work area to prevent slips and falls.

Proscribed Applications

  • Do not use Leona for food packaging applications.
  • Do not use Leona for medical devices designed or intended for intracorporeal implantation or contact, whether direct or indirect, with bodily fluids.
