Non-stick properties and bonding
properties- these two conflicting properties
meet together in harmony, realizing
direct bonding to other materials.
Reactive groups have been introduced so that the bonding properties manifest themselves above the melting temperature.
This makes the fluoropolymer capable of easily bonding to other materials
such as engineering plastic and metal while maintaining their
non-stick roperties, the attractive features of fluoropolymers, at
room temperature, thereby expanding the horizons of applications
as a composite material. |

Molding at low temperatures is possible.
Improved productivity and reduced costs.
(RP-4020)
With its melting point around 160 (compared to a 265 for
standard ETFE), NEOFLON EFEP RP-4020 can be processed at
lower temperatures. This allows simultaneous processing (e.g.,
co-extrusion) with nylons and other plastic engineering materials,
increasing productivity and lowering costs. |

NEOFLON EFEP can also be used in
applications requiring transparency.
Transparency to light has been improved
by about 30%*. (RP-4020)
Transparency to light has been improved while keeping the
features of a fluoropolymer. NEOFLON EFEP can certainly be
used in applications where visual observation plays an important
role such as chemical tubes and level indicators, but it also
shows excellent performance in applications where not only the
transparency but also durability and weather resistance are
required such as surface films for solar cells and roofing materials
(transparent films).
