K660 Foamcore Safety & Storage
This product is a flammable solid that may catch fire when exposed to high temperatures, heat sources, or open flames. It can undergo chemical reactions when in contact with strong acids or bases, which may affect its performance. Under normal operational conditions, no special fire or explosive hazards have been identified. Our company obtained ISO 9001:2015 quality system certification in 2023, ensuring that all standards comply with regulations.
From the date of receipt, the product has a storage life of 120 days at 25°C and 180 days at 15°C. Storing the product below 0°C is not recommended, as it may become brittle and affect its operational performance. If stored in a cold environment, the product should be softened at 25°C for more than one hour before use. If the storage period is exceeded, please verify its effectiveness before use; any potential adverse consequences are the responsibility of the user. During transportation, handle with care and avoid heavy loads.
All data contained in this document is for reference only and is considered reliable. We are not responsible for the results obtained by anyone using methods beyond our control. Due to the special nature of the materials, it is recommended that every future user conduct experiments or obtain on-site guidance from our engineers based on the data provided before the first use.
