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.

Preview to K 2019

K 2019 will welcome the international plastics and rubber industry 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 has been rising steadily. Messe Düsseldorf expects about 220,000 visitors from over 100 countries to attend the 21st edition of this global flagship fair for the polymer industry.

The current and future market for thermoplastic elastomers in medical and healthcare applications

It is estimated that the global market for thermoplastic elastomers (TPEs) for medical and healthcare applications will be of the order of 375,0000 t in 2019. It is likely that this market will grow with a CAGR of 8.5 % to 565,000 t by 2024. This represents the highest growth rate of all thermoplastic elastomers. The reason for such growth is a combination of a growing number of the world’s population seeking medical care as well as a move to replace a number of incumbent materials, in particular PVC. In addition, certain vulcanised elastomers are also likely to be replaced by thermoplastic elastomers at the same time. The main driving force behind these changes is the need to supply the market with products which have a much higher degree of purity. In Europe in particular, the introduction of the EU medical device and in vitro regulations 2017/745/EU and 2017/746/EU, which will come into force in 2020, will drive the producers of medical devices to examine alternative materials, which fully comply with these new regulations. Other geographical regions will also be forced to comply with these regulations, since from 2020 it will be very difficult to supply the European Union, unless all their products comply as well.

Stability and continuity – New VDI guideline 2017 Medical Grade Plastics defines requirements for plastics in medical, diagnostics and pharmaceutical packaging

Safety for patient and user is an essential requirement for medical products, in-­vitro diagnostics and pharmaceutical packaging. Subsequently, plastics grades used in medical have to fulfil particular requirements, i.e. constant properties, formulation lock or biocompatibility. Surprisingly, no standard has existed to define the requirements for medical grades so far. This gap has been filled recently by the new guideline VDI 2017 developed and launched by a work group of the German Engineer’s Society (VDI). This article addresses the development of the new guideline VDI 2017 “medical grade plastics” and presents the essential requirements to be covered by medical grade plastics (MGP).

Halogen-free flame retardant TPS compounds

Flame retardant thermoplastic elastomers (TPE) are gaining more and more attention in scientific work and R+D as well as in industries and markets with FR requirements. Styrene-based thermoplastic elastomers (TPS) have a very high market relevance due to their broad usability and versatile properties available via compounding. This includes also more and more technical applications and products where FR performance plays a key role. Albis Plastic GmbH recently complemented its TPE portfolio with flame retardant TPS compounds of the brand Solplast from Uteksol. This paper presents important properties and characteristics of these new compounds.

Flexible materials with PTC effect – Self-regulating heating systems based on electrically conductive thermoplastic elastomers with positive temperature coefficient (PTC)

Self-regulating heating systems are just one of many possible applications for polymer based positive temperature coefficient (PTC) thermistors. To create an electrically conductive polymer it is necessary to incorporate a conductive filler into the polymer matrix with a filler concentration around the percolation threshold. The specific property of PTC materials is the sharp rise of electrical resistance at an adjustable temperature. The steady state temperature depends on the selected polymer matrix, the applied voltage, the dimensions of the component or the electrodes. Besides this, the PTC effect is reversible. The materials available on the market often have an insufficient flexibility and a poor adhesion to the overmoulded electrodes. In order to solve these issues, the company Allod focuses on the development of flexible materials with PTC effect.

Excellent damping performance at elevated temperatures – Hydrogenated styrenic elastomer Hybrar SV-series

Lately, the efforts to reduce automotive weight for fuel efficiency has increased the problem of vibration and road noise and led to a reduction in passenger comfort and driving pleasure. The electrification of the automobile has decreased engine noise which was major noise source but other noises such as road noise, wind noise and transmission noise which were hidden by the engine have become more noticeable. As described above, the demand to reduce vibration and noise is increasing and is diversified. Damping materials, which can effectively reduce vibration and noise without significantly increasing the car weight, have been addressed as a countermeasure. Kuraray has recently developed new hydrogenated styrenic block copolymers with ­excellent damping performance at elevated temperatures. This article describes properties and benefits of the new materials.
