Fluon® ETFE LM-720A
- Chemical Family
- FluoropolymersPolyolefins
AGC Chemicals Americas, Inc. Fluon® ETFE LM-720A is a modified ethylene tetrafluoroethylene (ETFE) polymer. Unlike most other ETFE materials, LM-720A has a lower melting point of 225°C (compared to 260°C for most ETFE), improved chemical resistance and thermal stability, enhanced optical clarity, increased flexibility, and a higher limiting oxygen index of 40% (compared to 31% for most ETFE). It can be processed using conventional extrusion and injection molding techniques and is used for general-purpose extrusion and injection molding applications. Additionally, it has better stress crack resistance compared to LM-730A.

- Storage
The properties of Fluon LM-ETFE are not impacted by storage time. Storage and handling facilities should be designed to minimize contact with airborne contamination and the formulation of condensation on the resin. Fluoropolymers are not hydroscopic and will not typically need to be dried prior to use. However, masterbatches used to pigment fluoropolymers may contain materials that do absorb water and should be dried prior to use.
- Benefits
High resistance to heat; Excellent chemical resistance; Good physical toughness; Low smoke and flame characteristics: Fluon LM-ETFE is rated 94 V-0 by Underwriters Laboratories Inc.; Outstanding resistance to weather and aging; Good dielectric properties; Non-stick characteristics
