Fluon®LM-ETFE is a new fluororesin which combines the excellent heat resistant and mechanical properties of ETFE resin and the low melting point.

Features of Fluon®LM-ETFE

  • Processibility
  • Excellent heat resistance
  • Excellent flexibility and mechanical properties
  • Excellent chemical resistance
  • Excellent electrical properties
  • Nonflammable and safety
  • High transparency
  • Excellent surface property

Melting point is as low as 225℃. It has lower viscosity over 240℃, so processing is possible at temperature 50℃ lower than conventional ETFE.

It has a higher heat resistance than the ETFE resin, so it is usable over a wide temperature range from -200℃ to 180℃. Continuous usage at 180℃ is also possible. It also maintains stable electrical properties.

It has higher flexibility and mechanical strength. In particular, LM-ETFE withstands flex life for over 100,000 times. Further, LM-720AP has a higher elongation at high temperature.

It has excellent resistance to almost all chemical agents and solvents.

It has excellent electric insulation property and exhibits higher dielectric strength even as a thin film. In a wide frequency range, the dielectric constant similar to that of the conventional ETFE is presented.

Nonflammable material conforming to UL standards 94 V-0. Tasteless, odorless and nonpoisonous. Recommended for the food industry. Moreover, Fluon® LM-ETFE is US FDA compliance and registered in the inventory of Food Contact Substances at #481.

It has higher transparency than the conventional ETFE from visible to ultraviolet.

It possesses lower frictionality, anti-stick and excellent water and oil repellency. It possesses higher surface smoothness and reduces resistance of fluids.
