Precautions for handling LEONA™
The content of this document is based on materials, information, and data available at this time, and may be revised based on new findings. Please note that these are provided as information and are not guaranteed. Therefore, when using our products, please take full consideration of the usage environment, design, etc., and use them at your own risk after judging that there is no problem with the product.
1. Handling Precautions
The following items are the main points of care for handling the LEONA™ itself supplied to your company. Please use it for safe handling of LEONA™.
A separate material safety data sheet has been prepared for handling precautions for LEONA™. Please contact us and we will send it to you. We request that your company investigate the safety of additives, etc. that your company uses other than LEONA™.
(1) Precautions for safety and health
Care should be taken to avoid contact with the eyes, skin, and inhalation of gases generated when LEONA™ dries or melts. Also, avoid direct contact with hot resin. It is recommended to install a local exhaust system and wear protective equipment (protective glasses, protective gloves, etc.) for each work such as drying and melting.
(2) Precautions regarding combustion
LEONA™ is flammable and should be handled and stored away from heat and sources of ignition. If it burns, it may generate toxic or suffocating gas. Extinguishing can be done with water, foam or dry chemical.
(3) Notes on disposal
LEONA™ can be disposed of by incineration or landfill, but when disposing of it, please entrust it to an authorized industrial waste disposal company or local public body in accordance with the "Waste Disposal and Public Cleansing Law". Also, when incinerating by yourself, please use incineration equipment and follow laws and ordinances such as the Air Pollution Control Law. When incinerated, toxic gases such as carbon monoxide and suffocating gases may be generated.
(4) Notes on storage
Absolutely avoid resin contamination and moisture absorption. Store in a cool, dry place and start molding immediately after opening. Do not pierce the product bag or let it get wet. Also, do not return spilled resin to the product bag. It is a combustible material (synthetic resins) designated by the Fire Service Act, and should be handled in accordance with municipal ordinances. (Fire extinguishing facility, indoor storage facility, etc.)
(5) Notes on molding
The optimum resin temperature for molding LEONA™ is 270 to 310°C. If it is lower than this, there is a risk of local degradation of physical properties due to non-uniform plasticization. On the other hand, if it is higher than this, there is a risk of gas generation due to decomposition or poor appearance such as silver. However, there are some exceptions such as FR200 and FR370, so be sure to refer to individual catalogs before molding. Also, do not allow LEONA™ to stay in the molding machine cylinder for a long time in a molten state. Doing so may cause the resin to decompose, resulting in discoloration or deterioration of the molded product. In that case, once replace the inside of the cylinder with polyethylene, etc., and then perform molding.
2. Usage
