Barley Paper Insulation Tape

Description

Green shell paper is a kind of soft composite material, which is a two-layer insulating paper made of polyester film coated with adhesive and wood pulp insulating paper on one side. Insulation class: Class B Temperature resistance: 130°C. Uses: Green shell paper combines the good insulating properties of wood pulp insulating paper and the good dielectric strength of polyester film. It is widely used in electrical equipment, and is suitable for inter-slot insulation, inter-turn insulation and liner insulation of Class B motors. Appearance: Uniform surface, no fuzz, and no bubbles, pinholes, wrinkles and blemishes and other defects Green shell paper performance requirements Remarks: Double-sided adhesive tape (oil glue, hot-melt cotton paper double-sided adhesive tape) can be backed according to customer requirements; It can be divided into strips and sliced according to specifications.

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.
