Borealis and Topas Advanced Polymers have started collaboration on the development of a new class of engineering materials for capacitor film applications that will bridge the current performance gap between standard polymers and high-end plastics.

Higher-performance film capacitors are a crucial element in all power transformation systems that bring about the green-energy transition in a cost-efficient way

New Class of Engineering Material for Film Capacitor Applications

Antifog additives help to prevent water buildup on films. New technologies are intended to increase the service life of the films.

Films equipped with anti-fog additives enable more attractive packaging for food (left). Without such additives, water condenses in many cases on the packaging (right). This can negatively affect optical appearance of the food content, making it less appealing to consumers.

Moisture regulating packaging and antimicrobial active films protect food and keep it fresh longer. Films especially designed for these requirements have been tested for effectiveness, and the results indicate promise of success. 

Functional Films: Active Packaging Functions 

Packaging films fulfil so many complex requirements that they can suitably be called high-tech products. Intelligent extrusion and automation systems guarantee cost-efficient, flexible film production for virtually all applications.

Hygiene is one of the most important demands made on the production facilities when it comes to the production of foodstuffs. faigle Kunststoffe GmbH, Hard, Austria, has therefore developed a wrapping film made from a polyethylene (grade: PAS-PE) with added steriones. This film is used in prefermenting cabinets to guarantee hygienic conditions for raw bakery products.

In-Mold Labeling with three three-dimensionally molded films and two plastic components for a part measuring 380 x 250 x 50 mm: A project involving the radio/CD control panel of Ford’s C-Max placed high demands on moldmakers and film technology. The result can now be seen in automobile showrooms.

In-Mold Labeling: Three Films, One Part – and a Quartered Mold 

In the manufacture of plastic products such as film, quality assurance is essential. To make material testing during the manufacturing process as efficient and reliable as possible, Zwick GmbH & Co. KG, Ulm, Germany, has developed a robotic testing system with extended test chamber. Designated roboTest F, the unit is part of the Allround line. The feed for the tensile test takes place via a magazine holding up to 200 samples. The magazine itself consists of a support structure and a circulating chain with clamps, which hold the material samples. The clamps differ according to the sample type and form. It is thus possible to test film and textiles of different sizes with the same system.

August Mink KG, Göppingen, Germany, has introduced spreading rollers suitable for narrow webs and installation in very confined spaces. The type BSW-PP rollers are intended for use with web widths of up to one meter – a size often encountered in production of incontinence briefs. They do not require a separate drive and are almost wear- and maintenance-free.

New tasks lie ahead for polycarbonate films inside vehicles. The latest design ideas aim to create in the car interior a personalized, stylish ambience that creates a good atmosphere and offers high levels of comfort. This calls for large parts featuring numerous integrated functions and a flowing, intact surface characterized by depth of gloss.

With the help of a computer simulation it is possible to visualize the effects of the targeted positioning of functional materials and different sealing media on film flexural strength. Results for specimen systems show that ionomers, which have stiffnesses that can be adjusted within broad limits as well as very good sealing properties, offer a wide range of opportunities to reduce the thickness of such multi-layer films without at the same time having to accept a loss in flexural strength. 

Multi-layer Packaging Films: More Flexural Strength for Thin Films 

Newly developed photopolymer films can now be produced more economically. In comparison to materials available until now they do not require a chemical or thermal treatment after exposure. For this reason they are suitable for the cost-effective mass production of volume holograms. 

Photopolymers: Mass-Producing Holograms 

Radio-activated displays on thin, flexible plastic films are currently the most important innovation in the field of printed electronics. Such devices can be produced inexpensively in large quantities using modern rollto-roll processes. They enhance optically attractive, interactive applications, such as product marketing, brand protection and product authentication, as well as games.

The labels usually employed for food wrapped in plastic film are generally made from paper, cardboard or plastic film. Linerless adhesive label technology eliminates the substrate and thereby saves on weight and reduces packaging waste.

A machine manufacturer is expanding its wide program of cast and blown film lines with a system for water-quenched blown film extrusion. This provides a unique system portfolio for the production of flexible packaging. The article presents these extrusion processes, their specific characteristics and the resulting application areas.

Borealis and Topas Advanced Polymers have started collaboration on the development of a new class of engineering materials for applications that will bridge the current performance gap between standard polymers and high-end plastics.

The EPN (ethylene-propylene-norbornene) material now in development will increase the temperature resistance of film capacitors significantly – by 20°C to 35°C – in comparison to capacitors made of standard polymers. This will close the current gap between conventional polymers and costly high temperature plastics by enabling the use of polymeric film capacitors at endurance temperatures of up to 140°C. Combining the highest electrical purity with superior homogeneity, the new material should be designed for the production of ultra-thin and highly consistent films in the range of 2 to 6 microns gauge. Provided the appropriate processing parameters are in place, the new material is targeted to be suitable for use on BOPP (biaxially oriented polypropylene) film processing machines.

Higher-performance film capacitors are a crucial element in all power transformation systems that bring about the green-energy transition in a cost-efficient way. The new material class now being jointly developed by Borealis and TOPAS Advanced Polymers will be used in electric mobility units, particularly when higher endurance temperature resistance and consistent frequency control is essential, such as in electric vehicles and high-speed trains. It will also help address one of the major challenges of the green-energy transition by enabling the large-scale provision of more cost and energy-efficient capacitors for inverters that transform HVDC power generated from renewable sources on and offshore, such as from windfarms or photovoltaic arrays, into HVAC and back – with minimal energy loss.
