Product Q&A
Q:What is 6440 DMD epoxy prepreg?
A:
It is F-class composite insulation material, compounded by polyester non-woven fabric, PET film impregnated with epoxy resin, red surface, mainly used for motor insulation.
Q:What is its temperature resistance class?
A:
Thermal endurance class F, continuous operating temperature 155 centigrade.
Q:Does this material need hot-press process?
A:
Yes. Under proper heating and pressing condition, epoxy resin cures to achieve bonding and integral insulation structure.
Q:What main application scenarios for 6440 prepreg?
A:
Mainly for slot insulation, phase insulation of low-voltage motors, small transformers, electrical coil insulation.
Q:What is the difference between ordinary DMD and 6440 epoxy DMD prepreg?
A:
6440 is epoxy pre-impregnated type, can realize self-bonding after hot pressing; common DMD without epoxy needs extra varnish for bonding.
