Description of DMDM Insulation Paper

DMDM insulating paper is four-layer flexible composite material which is composed of two-layer polyester fiber non-woven(D) and two-layer polyester film(M) overlapped alternately and glued together.
Four-layer DMDM insulating paper using polyester film and polyester fiber non-woven as raw materials, ensuring that the series products have excellent mechanical property, temperature and corrosion resistance, high rigidity, hardness and toughness, and good chemical resistance and oil resistance. 
DMDM has higher mechanical strength and electrical property compared with DMD with a same thickness.
