三.Packaging, labeling, storage:


1.Packaging: non-woven with plastic wrap each roll, then a layer of waterproof plastic bag outsourcing, die with the corresponding ends of the wood core or plastic core plugged.

2.Logo: packaging bags should identify the manufacturer, product name, type, size, batch number, net weight, production date and other signs.

3.Storage: 7031 non-woven fabric should be stored below 40 ℃ in a cool, dry, clean and well-ventilated warehouse, not near the fire and Heating, shall be subjected to direct sunlight, the storage period of 1 year.

四.Range:

Widely used in composite materials (DMD, DM, DMDM), Mica reinforcing materials, electrical laminates, insulating paint Buji Bu, electrical appliances, transformers, motors coil ends bandaged, but also for small, flexible cable, civilian electrical cables, communications cables, and various types of paper instead of an insulating material.
