UL 1mm Thickness Halogen Free GPO3 Fiberglass Sheet

Halogen-free GPO3 with UL recognized and 1mm thickness reach UL94-V0

GPO3 sheet is a environmental protection material (green product ) , because of it is not content the halogen . As we known , so many insulation materials add the halogen (such as bromine) to enhance fire inflaming retarding grade UL94-V0 . However , the filler material of GPO3 is calcium carbonate , it is the halogen free material and meet UL94-V0 . Halogen will migerl injurious to health of persons .

The GPO3 material is also recognized by UL/ROHS/REACH/EN45545 etc., as we known , more and more customers requested certified by UL and meet requirements of ROHS/REACH , if the material did not have certicated of them , it will be difficult exporting to Europe and North America.

The GPO-3 sheet from our company can reach UL94-V0 on fire resistance property , as we know that it will more easy to burn if the thickness is small . According to IEC and GB standard , no any clause stipulate the GPO-3 should meet UL94-V0 when thickness less than 3mm , most of GPO-3 sheet with thickness less than 3mm can reach UL94-V2 only and even HB grade , it means that it has the risk to burn during electrical equipment running .

What is the features of GPO3 material ?

1. It is halogen free material , no any halogen material as fire retardant .

2. High strength of bending , tensile properties , tensile strength can meet 162MPa ;

3. Excellent Vertical Compression Strength , the test value is more than 490MPA

4. Great running temperature index , long working temperature can meet F class , 155℃

5. Arc resistance reach 180 second .

6.Very low water absorption , it means better insulation strength when running in humid environment.

What is application of GPO3 material ?

With the technology development and social progress , more and more electrical products have been came into the lives , more and more peoples take care of the health of electrical products , save and green products are the same important into our lives . GPO3 material has been more and more widely used in every industry by virtue of more save and more environmental protection , such as

photovoltaic power generation , rail transportation , wind energy , power transmission and distribution .

It has been making every kinds of insulating structural parts , for example :

1. Air gap , top and bottom cover in transformer
2. Comb type bracket in dry transformer
3. Arc extinction sheet in moulded case circuit breaker
4. Bus bar supports in switch cabinet
5. Phase and end barriers in frequency changer
6. Carbon brush holder in motor
7. Top cover in battery box .
