Wholesale Price G10/Fr-4 Glass Epoxy Sheet - D370 SMC Molded insulation sheet – D&F Detail:

D370 SMC molded insulation sheet (D&F type number:DF370) is a kind of thermosetting rigid insulation sheet. It is made from SMC in mold under high temperature and high pressure. It is with UL certification and passed the test of REACH and RoHS, etc. It is also called as SMC sheet, SMC insulation board,etc.

SMC is a kind of sheet molding compound which consists of glass fiber reinforced with unsaturated polyester resin, filled with fire retardant and other filling substance.

SMC sheets have higher mechanical strength, dielectric strength, good flame resistance, tracking resistance, arc resistance and higher withstand voltage, as well as low water absorption, stable dimension tolerance and small bending deflection. SMC sheets are used for making all kinds of insulating boards in high or low voltage switch gears. It can also be used to process other insulation structural parts.

Thickness:2.0mm~60mm

Sheet size:580mm*850mm, 1000mm*2000mm,1300mm*2000mm, 1500mm*2000mm or other negotiated sizes

Technical Requirements

Appearance

Its surface shall be flat and smooth, free from blisters, dents and obvious mechanical damages. The   colour of its surface should be uniform, free from obvious exposed fiber. Free from obvious contamination, impurities and obvious holes. Free from delamination and crackles at its edges. If there are defects on the surface of the product, they can be patched. The superabundant ashes must be cleaned.
