Print works!

When I joined the publishing house, I was told by every other person that there was no future for print and that print budgets would be reduced or cut in favour of online advertising.

Today – 7 years later – this statement has fortunately not been confirmed.

Online information about what is currently happening spreads faster and more virally. But print continues to work in the digital age. On the one hand, print media are regarded as more trustworthy [1] thanks to journalistic research, analysis and evaluation.

On the other hand, we humans are multisensory beings. Our brain still functions as it did 10,000 years ago – regardless of the digital revolution.

We see the words and images.
We smell the paper.
We even hear the rustling of the pages.
We feel the pages and the weight of a book or magazine.
We read with all our senses!

Most of all, our brain loves haptics! 40 % of our brain is permanently occupied with haptics. The sense of touch is our sense of truth. Haptically optimised communication generates more attention, remains longer in the minds and generates a greater feedback. Haptic perception also makes advertising credible.

In this way, print media reach people because they offer orientation and security in an age of digital information overload and fake news.

Information is fast – but truth takes time!

So take your time ... in these days!

Yours,
Indira Gupta

[1] In a survey by Best4Planning (b4P), 76 % of respondents considered print media to be “very trustworthy”. When various events are reported, 60 % of respondents believe newspapers and magazines, but only 7 % believe digital media such as FB and Twitter.

K 2019 – Driving force for innovation and international business in the plastics and rubber industry

K 2019 will welcome the international plastics and rubber industry to its exhibition centre in Düsseldorf, Germany, from 16 until 23 October 2019. As per 26 June 2019, the list of exhibitors included 3,157 companies from 60 countries. The largest group of exhibitors comes as usual from Europe, particularly from Germany (915), Italy, Austria, Switzerland, France, and Turkey, but there is also an impressive number of participants from the USA. At the same time, the number of participating Asian companies and the exhibition area that they have booked has been rising steadily, and this year, particularly China, Taiwan, India, Japan and South Korea will be impressing visitors with their prominence. Messe Düsseldorf expects about 220,000 visitors from over 100 countries to attend.

When a butterfly holds a smartphone

Turning an original idea into series production: a combined team from university and industry has been jointly developing an innovative design and production concept for a car smartphone holder. The rigid-flexible combination of liquid silicone rubber (LSR) with polycarbonate (PC) is produced by cost-effective multi-component injection molding.

Electromobility report 2019 – Sales trends in core markets

The “Electromobility Report” of the Center of Automotive Management (CAM) analyses e-mobility market and sales trends of automotive manufacturers on a regularly basis. Main focus are the core markets of China, USA, and the European Union. Different market ramp-up scenarios for 2025/2030 are designed considering key-influencing factors like charging infrastructures, regulations, products and the electromobility strategies of OEM. Some findings of the new “Electromobility Report 2019” are presented below.

An alternative method for the vulcanization of rubber articles

Zinc oxide was treated with a sulfenamide accelerator by vacuum evaporation of a suspension of ZnO in a solution of the accelerator in dichloromethane to provide a convenient single material component to use as additive. The optimum quantity of the accelerator in the additive was found to be 350 mg/g. A large batch of the surface-modified zinc oxide with this composition (referred to as the ‘TBBS/ZnO powder’) was then prepared. The effect of an increasing loading of the TBBS/ZnO powder on the cure properties of ethylene-propylene-diene rubber (EPDM) and polybutadiene rubber (BR) containing elemental sulfur was subsequently measured. When the loading of the TBBS/ZnO powder in the rubbers was raised progressively, the scorch time was unaffected and the optimum cure time reduced. The rate of cure kept rising until it reached an optimum. The crosslink density increased substantially as the loading of the TBBS/ZnO powder in the rubber was raised progressively. All the indications are that the use of the TBBS/ZnO powder in combination with sulfur in the cure system improves efficiency of the vulcanization process, reduces cost and harmful effects while also shortening the cure cycle. The surface modified TBBS/ZnO powder is a viable alternative chemical additive for the sulfur vulcanization of rubber.

VDMA: Focus on Circular Economy at K 2019 – Interviews with Ulrich Reifenhäuser, CSO, Reifenhäuser Group, Dr. Christoph Schumacher, Head of Marketing and Corporate Communications, Arburg and Alfred Stern, CEO, Borealis

The K 2019 trade fair for plastics and rubber will take place from 16 – 23 October 2019 in Düsseldorf, Germany, where the VDMA Plastics and Rubber Machinery Association will shine the spotlight on the recycling sector and show how closed loops can work effectively. The following interviews will shed light on why it is doing this and the significance of the “Circular Economy” for member companies of the trade association. In this contribution, Ulrich Reifenhäuser, Chairman of the Board of Management of the association, Dr. Christoph Schumacher, Head of Marketing and Corporate Communications at Arburg, and Alfred Stern, CEO of Borealis AG, will give their views on the subject.

Low temperature cure of liquid silicone rubber

Liquid silicone rubber (LSR) is a high-performance elastomer used in many markets and applications. New application trends require enhanced design flexibility, process efficiency and co-molding using combinations of different material types. In such co-molding applications, the cure temperature of LSR is inherently limited by the thermal stability of the overmolded counterpart, and conventional high process temperatures often cannot be used. A new generation of low temperature cure (LTC) LSR materials that cure between 90 °C and 120 °C is now available to overcome those co-molding challenges and enable new designs and applications. At conventional high process temperatures and in existing applications, LTC LSR can provide for new levels of process efficiency.

New ultra-high molecular weight EPDM for automotive, consumer, and infrastructure applications

An ethylene propylene diene (EPDM) rubber with an ultra-high molecular weight (UHMW) is desired in those applications where the EPDM rubber is highly filled with filler(s) and process oil in order to reduce the overall compound costs. In addition, such compounds are expected to exhibit improved processability, while providing superior physical and compression set properties at different temperatures. On the other hand, UHMW of EPDM is crucial for the complete phase-inversion of crosslinked EPDM in continuous polypropylene (PP) phase during the thermoplastic vulcanizate (TPV) production [1]. Such UHMW EPDMs are generally extended with 75 phr to 100 phr oil for improved processability and superior manufacturing efficiency. Some of the application examples include TPVs, low hardness seals and gaskets, injection molded goods, automotive and construction rubber profiles, etc. In this paper, the use of the new UHMW Nordel 4655OE in automotive, consumer, and infrastructure applications is described. Several case studies are presented highlighting the advantage of this UHMW EPDM in order to achieve better physical properties and compression set properties in low hardness compounds. Dow’s sustainability commitment to the rubber industry is also briefly highlighted.

Mechano-adaptive composites for future applications

Futuristic concepts of robotics, autonomous vehicles, and artificial intelligence will replace heavy machines with light weight, active and smart materials. Already, a lot of smart materials (shape memory alloys, magneto-rheological elastomers, dielectric elastomers, etc.) have emerged as potential materials for several futuristic concepts. In this article, the focus is given to special and novel smart materials known as mechano-adaptive composites, which are still under research, but promises huge capabilities and applications in the future.
