6520 Barley Paper Lamination

Our 6520 Barley Paper Lamination is a traditional insulation material. Barley paper is an electrical insulation paperboard. Its color is light yellow. It has a texture on the surface. It looks a bit like barley. That is why it is called barley paper. The number 6520 comes from China's insulation material standard. 6520 stands for polyester film laminated with barley paper. So our 6520 Barley Paper Lamination has one layer of PET film stuck onto one layer of barley paper. This gives you the stiffness of barley paper and the strength of PET film. A low-voltage electrical factory came to us. They make circuit breakers. Circuit breakers need insulation spacers. They used pure barley paper before. But barley paper absorbs moisture easily. When it gets wet, its insulation performance drops. We recommended our 6520 Barley Paper Lamination. You put the PET film side facing out. Then it does not absorb moisture. They tested 1000 products. All passed. Now they buy 500 kg every month.

Barley paper is made from wood pulp. It has some elasticity. It can bend. It is not as hard as pure PET. So our 6520 Barley Paper Lamination is good for insulation parts that need to fit a certain shape. We can punch this material into various shapes. We have a punching machine. We can make thicknesses from 0.15 mm to 1.5 mm. The thickness tolerance is ±0.03 mm. That is twice as tight as the industry standard. Our 6520 Barley Paper Lamination is a high-volume product. The unit price is not high. But the quantity is large. Many low-voltage electrical factories need several tons each month. If you have these customers, our 6520 Barley Paper Lamination can give you stable supply. Our annual capacity is 1000 tons. We will not run out of stock.
