UPGM201 lamination sheet is also an unsaturated polyester glass backing. UPGM203 board (GPO-3) is very popular in the market, the main difference between it and UPGM201 (GPO-1) is electrical performance.

UPGM201 lamination sheet is a cost-effective general purpose insulating board. If the application industry has specific requirements for arc resistance, flame resistance and carbon tracking resistance, UPGM203 is always the first choice because it provides good electrical properties and good physical strength in moderately heat-resistant applications. If there are no specific requirements for arc resistance, flame resistance and carbon tracking resistance, and the application is general application, UPGM201 is also a good choice because its price is lower than UPGM203. Apart from the above differences, everything else is the same.

5. FAQ

1. Is Zibo Haichen Composite a manufactuer for UPGM201 (GPO-1) sheet?

A: Zibo Haichen Composite is a manufacturer that integrating the production of UPGM201(GPO-1) sheet and machining processing.

2. Why choose us as a supplier?

A:We are factory and we will provide our best service as below:

1).Once we cooperate, our factory has special personnel to connect with customers and provide one-to-one service.

2).We will have regular products in stock, and special products will provide the fastest delivery date.

3).We are a factory and a primary source of goods. We will provide the best products and prices.

4).We ensure that the products we produce will be consistent with the quality of the samples we provide.

3.What is the difference between Epoxy sheet and UPGM201 sheet?

A:Composite material sheet in which synthetic resin is used as matrix material. According to the different matrix resin used, it can be divided into epoxy resin, unsaturated polyester resin, phenolic resin FRP and so on.Epoxy resin is characterized by high compression and tensile strength. It can still maintain good mechanical properties under high temperature for a long time. It has good arc resistance, UV aging resistance and climate resistance. Unsaturated resin is characterized by light weight, high strength, good corrosion resistance, excellent electrical performance, unique thermal performance, excellent processing performance and good material designability.

The disadvantage of epoxy resin is that the price is high, which is more than twice that of unsaturated polyester resin, and the curing time is long (unsaturated polyester resin can be cured within 1 hour, while epoxy resin needs more than 10 hours). These two disadvantages material cost and labor cost of epoxy resin is higher than unsaturated polyester resin.UPGM201 sheet usually use unsaturated polyester resin.

4. How many kind of insulation sheet in the market?

A: Generally there are main epoxy fibergalss cloth sheet inlcuding 3240 sheet,G10,G11;phenolic fibergalss cloth sheet;bakelite Sheet;UPGM203 sheet and SMC sheet.

5. What are the main categories of solid insulating sheet material?

A:Solid insulating materials can be divided into inorganic and organic.

Inorganic solid insulating materials: mainly including mica powder and mica products, glass, glass fiber and its products, as well as electric porcelain, alumina film, etc. They are resistant to high temperature, not easy to aging and have considerable mechanical strength.

Fiberglass can be made into silk, cloth and tape. It has much higher heat resistance than organic fiber and plays an important role in the development of insulation structure to high temperature.

Organic solid insulating materials: such as paper, cotton cloth, silk,, curable vegetable oil, etc. These materials have flexibility, can meet the application process requirements, and are easy to obtain.

6. How is it graded into UPGM201 (GPO-1) and UPGM203 (GPO-3)?

A: It is NEMA grade,NEMA have GPO-1,GPO-2 and GPO-3.

7. What is the difference between UPGM201 (GPO-1) and UPGM203 (GPO-3)?

A: The main difference between UPGM201(GPO-1) and UPGM203 sheet(GPO-3 sheet) is electrical performance,UPGM201(GPO-1) have lower arc resistance and track resistance.

8.Is sample free if we require UPGM201 (GPO-1) and UPGM203 (GPO-3) a sample?

A: Sample is free but need customer to afford the shipping cost,we will deduct this cost if we have order cooperation.

9.What is delivery time?

A: We capacity is 300T per month and we will provide 7-15days delivery time according to the quantity required.
