Fluoropolymer Films
Fluoropolymer films are state of the art materials providing to parts or production processes outstanding chemical resistance, transparency, weather resistance, heat resistance, water absorption, electrical characteristics amongst others. They are the best solution for a growing number of industries such as electronic, machine, automotive and semiconductors.
DESCRIPTION
Benefits of Fluoropolymer Films
Used as components, or in manufacturing processes, high-performance fluoropolymer films are considered because of their outstanding resistance to high temperature and chemically aggressive environments. They meet the current demands of an increasingly diversified and sophisticated number of industries such as electronic, machine, automotive and semiconductors:
- Semiconductors manufacturing equipment require chemical-resistant liners for etching bath, restraining process downtime
- Pharmaceutical packaging producers are developing next-generation drug containers, improving barrier resistance of drug delivery systems, cap liners, and plunger laminates
- Construction and infrastructure segment players are continuously seeking for sustainable solutions such as water-repellent architectural fabrics, anti-graffiti coverings, protection against extreme corrosion, fading or cracking.
Features of Fluoropolymer Films
To meet the growing demand for high-performance films, DAIKIN has developed a range of films and sheets based on the fluorine technology. They allow for their users to benefit from the outstanding fluoropolymers inherent properties:
The several ranges of film are available under the NEOFLON brand
- NEOFLON PFA Film: having superior chemical resistance and thermal stability
- NEOFLON FEP Film: offering excellent heat resistance, non-stick and electrical performance
- NEOFLON ETFE Film: transparent with unique mechanical properties
- NEOFLON PCTFE Film: high moisture resistance, chemical resistance, transparency and mechanical strength at low temperature
Applications
The range of NEOFLON Films are suitable for use in a wide variety of applications such as anti-corrosive linings, composite part mold release, industrial roll covers, circuitry, pharmaceutical cap liners, sterile packaging, cable insulation, hot melt adhesive, microphone electret membranes, photovoltaic cell glazing (back sheet), anti-graffiti coverings, erasable surface, coverings, automotive airbag systems, fuel hose permeation barrier, hot melt adhesive and more.
NEOFLON films adapt to conventional processes and secondary operations such as heat seal, thermoforming, welding, and heat- bonding, lamination, die-stamp. Each of the film grades is available in various, size, weight and thicknesses to meet the most specific requirements
