Note: The impurity particle size is calculated based on the size between two points with the largest distance.
3. Packaging, storage and transportation:
Insulation materials are sealed and packaged in double corrugated cartons with trays at the bottom, divided into two packaging specifications: 250kg and 500kg.
Insulation materials should be stored and transported in a clean, dry and ventilated warehouse, and the storage temperature should not be low. at 10°C.
Insulation materials should not be damaged by abnormal conditions such as sun exposure, rain and water immersion during transportation. Store and transport as non-dangerous goods.
