Good Quality 6641 F Class Dmd Flexible Laminate For Slot Insulation - DF205 Modified Melamine Glass Cloth Rigid Laminated Sheet – D&F
Good Quality 6641 F Class Dmd Flexible Laminate For Slot Insulation - DF205 Modified Melamine Glass Cloth Rigid Laminated Sheet – D&F Detail:
DF205 Modified Melamine Glass Cloth Rigid Laminated Sheet consists of woven glass cloth impregnated and bonded with a melamine thermosetting resin, laminated under high temperature and high pressure. The woven glass cloth shall be alkali-free.
With a high mechanical and dielectric properties and excellent arc resistance, the sheet is intended for electrical equipment as insulation structural parts, where high arc resistance is required. It also passed toxic and hazardous substance detection (RoHS Report). It is equivalent to NEMA G5 sheet, MFGC201, Hgw2272.
Available thickness: 0.5mm~100mm
Available sheet size:
1500mm*3000mm、1220mm*3000mm、1020mm*2040mm,1220mm*2440mm、1000mm*2000mm and other negotiated sizes.

| Remarks:1 Remarks: If the caculated average of measured thickness is between two thcikness mentioned in this table, the values will be acuired by interpolation. If the caculated average of measured thickness is less 0.5mm, the vales will not be over 17mg. If the caculated average of measured thickness is over 25mm, the value will not be over 61mg.2 .If nominal thciness is more than 25mm,it shall be machined to 22.5mm on one side only. The machined side should be smooth. | |||||
Packing And Storage
The sheets shall be stored in a place where temperature is no higher than 40℃, and be placed horizontally on a bedplate with a height of 50mm or above. Keep away from fire, heat (heating apparatus) and direct sunshine. The storage life of sheets is 18 months from the date of leaving factory. If the storage duration is over 18 months, the product also could be used after being tested to be qualified.
Remarks and Precautions for Application
1 A high speed and small cutting depth shall be applied when machining because of sheets’ weak thermal conductivity.
2 Machining and cutting this product will release much dust and smoke. Suitable measures should be taken to ensure dust levels are within acceptable limits during operations. Local exhaust ventilation and using the suitable dust/particle masks are advised.
3 The sheets are subject to moisture after being machined, a coating of insulating vanish is recommended.
