Description

Highland barley paper is made of fluoroplastic highland barley. Its surface is smooth, its color is mostly dark green, and its thickness has various specifications.

Because it has the characteristics of wear resistance and aging relief, and it also has the effect of withstand voltage, so when the human body is in close contact with electronic products, there will be no electric shock

Qingke paper has good mechanical strength, electrical strength and toughness, so it is used as insulating material in motors, electrical appliances, instruments and other equipment. Mainly spacers between metal parts. Highland barley paper is also common in lithium batteries. Highland barley paper is used in lithium batteries. It is an insulating paper with good mechanical strength, with a thickness of 0.1-0.3 mm, a dark gray-green color, and easy moisture absorption. It is used as an insulating backing paper.
