3021 페놀 판지

당사의 3021 페놀릭 페이퍼보드(Phenolic Paperboard)는 예산 친화적인-단열 보드입니다. It uses insulation paper as the base material. It uses phenolic resin as the binder. The color is brown. 표면이 윤기나게 보입니다.. 3021는 중국 국가 표준 번호입니다. What is the difference between 3021 and 3240? 3240 is glass cloth epoxy board. It has high strength but a higher price. Our 3021 Phenolic Paperboard is paper-based. It has lower strength but a much lower price. The breakdown voltage and insulation resistance are still good enough for many applications. A low-voltage electrical factory came to us. They needed insulation shims with 1 mm thickness. The quantity was large. They used 5000 pieces every month. Before, they used 3240. The cost was too high. We recommended our 3021 Phenolic Paperboard. The price was half. The breakdown voltage was 10 kV. Their low-voltage equipment only runs at 690 V. That was more than enough. They switched to our 3021 Phenolic Paperboard. They saved 80,000 RMB a year.

The performance of our 3021 Phenolic Paperboard is as follows. Bending strength in the machine direction is 120 MPa. In the cross direction, it is 100 MPa. Breakdown voltage in the vertical direction is 12 kV. Water absorption is less than 2%. Temperature class is E (120℃). The machining property is good. Drilling does not cause delamination. Our special advantage is that we can make very thin 3021 Phenolic Paperboard. Thickness from 0.3 mm to 0.8 mm. Many factories cannot make it that thin. We have special presses. The thickness tolerance is ±0.05 mm. 우리는 OEM을 지원합니다. You tell us the size. 우리는 당신을 위해 그것을 잘라. We can also punch it into shapes. MOQ는 500kg입니다. 무료 샘플을 사용할 수 있습니다.
