R-5600-T Thick Mica Sheet  |
|
|
|
R-5660-T series of Thick Mica Plate is Rigid Mica Plate with thickness more than 5mm , it is mica laminates designed for providing outstanding resistant to high voltage and to high temperature.
R-5660- T series has acquired UL94V-0 approval with the file No.E231452, TUV approval on environmental safe (the file No. Z05811263 ), SGS-RoHS approval with the file No. SH6148278/CHEM, and has been authorized for use in contact with food products (certificate from the FDA with the file No. RJSSZ060586FDA).
R-5660- T series has two species:
| |
• R-5660- T 1: Muscovite Thick Mica Plate , Silver color, Heat resistance: 500 ℃ / 932°F (In constant operation), 750 ℃ / 1382°F (in intermittent operation) .
• R-5660- T 3: Phlogopite Thick Mica Plate , Golden/Amber color, Heat resistance: 750 ℃ / 1382°F (In constant operation), 1000 ℃ / 1832°F (in intermittent operation) . |
|
|
|
|
|
• Excellent resistance to heat up to 1000°C .
• Excellent in di electric strength .
• E xcellent flexural strength. Thick mica plate is usually processed into mica washer, R-566-T series is to process and not delaminated.
• Environment safe. R-5660-T thick mica is free of sheet have no asbestos and heavy metal.
|
|
| |
• Size: Sheets of 1000 x 600 mm 1000 x 1200 mm 1000 x 2400mm
