Electrically conductive plastic
Electrically conductive plastic… is that a thing? Yes, amazingly it is! So, how is this achieved and what would this be used for? Read on to find out.
At Diamond Coatings, we specialise in a range of conductive and anti reflective coatings. Using state of the art technology within our own facilities, we are able to apply a conductive coating to glass, PET films and yes, plastic..
Our conductive coating is Indium Tin Oxide. More commonly known as ITO, this is both transparent and conductive, making it ideal for a variety of uses across a multitude of industries.
Electrically conductive plastic – How?
A thin and uniform coating of ITO can be applied to a variety of plastics including polycarbonate, polyester and acrylic within a vacuum and at a low temperature. Diamond Coatings have actually designed and built their own production plant, which has the ability to produce conductive plastic using ITO coatings.
We have the ability to coat flat, curved or injection moulded shapes of up to 1000 mm by 1000 mm in size with sheet resistances ranging from 8 to 1000 Ohms/sq
Applications of electrically conductive plastic
There are a huge number of applications for a electrically conductive plastic, such as EMI/RFI shielding and flexible printed circuits, resistive touch screens, medical sensors, membrane switches, electroluminescent lamps and optical clear heaters.
The most widely used application listed above is possibly the resistive touch screen. These are common in public facing areas (touchscreen order facility in takeaway restaurants, ticket ordering kiosks, touch ATM machines as some examples)
Types of conductive plastic
Polycarbonates – Widely used within modern manufacturing, these substrates boast a range of interesting properties including optical properties and both impact and temperature resistance. Available with/without anti-reflective or hard-coat coatings, polycarbonates are a group of easily machined and coated thermoplastic polyesters.
Offering different polycarbonate grades with flame retardant and other properties, we can also supply these substrates with anti-reflective finishes suitable for a wide range of applications.
Acrylic – Also available with/without hard-coat/antireflective coatings, acrylic substrates are better optically although not as resilient as polycarbonates.
Further scratch resistant properties may be added together with anti-reflective coatings.
Resembling glass yet possibly superior to glass (the main advantage being weight, as acrylic is significantly lighter than glass), our acrylic substrates are hand-made and invariably inspected to exceptionally high optical specifications.
ITO Coated Films – In addition, we offer a range of ITO coated films on substrates including polyester, polyimide, polypropylene, and polycarbonate.
Diamond Coatings supplies ITO coated electrically conductive plastic to large numbers of original equipment manufacturers within electrical and electronic industries throughout Europe, the Far East and the USA.
