Polyonics has greatly expanded its PolyFLEX™ line of flexible substrates in terms of size, function and performance. The new materials include ultra thin (13 µm) amber and black polyimide films, a variety of white, clear and matte black top coats, a new harder and more durable white top coat?aimed at high temperature laminations?and a variety of high performance films with antistatic and flame retardant functionalities.
Westmoreland, NH (PRWEB) March 05, 2013
The use of flexible and printed electronics in virtually all industries continues to expand. Along with it comes an increased demand by global electronics manufacturers, contract manufacturers and specialty die cut converters for durable and highly printable flexible substrates in micro-thin constructions.
To support this demand, Polyonics has developed a broad line of flexible substrates and films that include ultra-thin polyimide in a variety of thicknesses, colors and coatings. The substrates provide the ideal physical and electrical properties for flexible circuits. They are designed using polymer coating technologies developed for the extreme temperatures and harsh environments found in PCB manufacturing. The coatings allow printing with conductive, semi-conductive and resistive inks via Flexo and Screen printing. Along with printability, these constructions can also provide thermal management, electrical isolation, the dissipation of electrostatic charges?to help prevent ESD in static sensitive devices (SSD)?and fire retardant options.
Polyonics, PolyFLEX and Polyimide
Polyimide is the preferred material for applications requiring a high degree of dimensional stability after exposure to extreme temperatures (up to 300°C). In addition, polyimide offers a high resistance to chemicals and is light weight and flexible. These properties, combined with polyimide's superior electrical properties make it an ideal substrate. However, printing directly on polyimide has always been a challenge due to its poor ink wetting and adhesion properties. Corona treating polyimide is sometimes used, but with little success.
PolyFLEX flexible substrates take full advantage of polyimide’s unique characteristics plus include proven Polyonics clear, white and matte black printable coatings. These polymer coatings have been evaluated by leading conductive ink suppliers as providing increased ink receptivity, superior ink adhesion and high resolution printing. The PolyFLEX formulations and coatings are the most durable, highest resolution and most printable polyimide films available on the market today.
PolyFLEX Product Line
PolyFLEX substrates are available in thickness of 13 µm (0.5 mil), 25 µm (1 mil), 50 µm (2 mils) and 125 µm (5 mils) and come in the traditional amber polyimide plus black polyimide and matte black coated amber polyimide. All Polyonics substrates are all REACH and RoHS compliant with the flame retardant versions being tested to UL94 VTM0 and the antistatic products having surface resistances between 10^4 and 10^9 Ohms?the heart of the dissipative zone?to help protect SSDs.
Typical printed electronics applications include:
Polyonics Flame Retardant Films
The pain point in many electronic devices?in particular Li-ion batteries?concerns finding a tape or film that isolates or insulates the device's components from heat while not propagating a fire should one occur. PolyFLEX flame retardant films meet both of these requirements. They help manage the thermal environment within the device, isolate specific components from heat and will not contribute to the burn cycle.
PolyFLEX flame retardant films can provide,
High Opacity Films for Optical Devices
The pain points associated with optical devices involve minimizing light leakage and maximizing light reflectivity. These two issues can sometimes be required to work in parallel as is the case with some LED applications. In this case, being able to satisfy both requirements with a single film not only improves the product's performance, but its operational efficiency as well.
PolyFLEX substrates include both high opacity versions as well as constructions that are both highly opaque and highly reflective. The films have found success in a variety of optical devices among them cameras, optical encoders and LEDs.
