Special Design for 4 By 8 Fiberglass Sheets - 347F High Strength Epoxy Glassfiber laminated sheet (Thermostability is grade F) – Xinxing
Special Design for 4 By 8 Fiberglass Sheets - 347F High Strength Epoxy Glassfiber laminated sheet (Thermostability is grade F) – Xinxing Detail:
Product Description
This product is a laminated sheet which made with processed non-alkali glass fiber cloth as the backing material, by hot pressing with grade F benzo oxazine resin. It has good mechanical and electrical properties,and flame retardant, especially has high mechanical strength retention and excellent electrical properties under high temperature.Suitable for grade F motor and electrical equipment as high quality insulation structure , has the advantage of good machinability and wide applicability in the similar products.
Features
1.Good mechanical and electrical properties;
2.High mechanical strength retention and excellent electrical properties under high temperature;
3.Moisture resistance;
4.Heat resistance;
5.Temperature resistance:Class F,155℃
6.Good Machinability and wide applicability
7.Flame retardant property:UL94 V-0
Compliance With Standards
In accordance with GB/T 1303.4-2009 electrical thermosetting resin industrial hard laminates – Part 4: epoxy resin hard laminates.
Appareance: the surface should be flat, free of bubbles, pits and wrinkles, but other defects that do not affect the use are allowed, such as: scratches, indentation, stains and a few spots.The edge shall be cut neatly, and the end face shall not be delaminated and cracked.
Application
The technical data of 347F is similar to FR5,Suitable for grade F motor and electrical equipment as high quality insulation structure.
