Description

CALMICAGLAS® 2005 and CALMICAGLAS® 409 consist of mica paper based on calcined muscovite, a glass cloth carrier and thermosetting epoxy-novolac. CALMICAGLAS® 2005 and CALMICAGLAS® 409 are very flexible glass mica paper combinations, which can be easily wrapped in full width by hand or taped on automatic taping machines. After curing in a hot

press an insulation with excellent dielectric, thermal, mechanical and chemical properties is obtained.

Application

CALMICAGLAS® 2005 and CALMICAGLAS® 409 are used for the insulation of bars and coils of motors and generators up to highest output and nominal voltage. CALMICAGLAS® 2005 and CALMICAGLAS® 409 are also suitable for the fabrication of moulded parts e. g. as commutator caps, tubes and cylinders. CALMICAGLAS® 2005 is interleaved and especially used when temperatures > 30 °C may occur during transportation or storage.

Processing Advice

• Pressing conditions (to achieve form stability):
• Temperature: 130 °C – 180 °C
• Pressure: 2 – 3 N/mm²
• Time: 8.0 – 0.5 hours
• Example: 1 hour at 160 °C and 2 N/mm²
• Fully cured status is achieved after 4 hours at 160 °C.
