Product Q&A

Q:What is 6440 DMD epoxy prepreg?

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?

Thermal endurance class F, continuous operating temperature 155 centigrade.

Q:What is the difference between ordinary DMD and 6440 epoxy DMD prepreg?

6440 is epoxy pre-impregnated type, can realize self-bonding after hot pressing; common DMD without epoxy needs extra varnish for bonding.

Q:Does this material need hot-press process?

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?

Mainly for slot insulation, phase insulation of low-voltage motors, small transformers, electrical coil insulation.
