The Fascination of Chemistry
WACKER'S AUDIO MAGAZINE
Once a month, our "Fascination of Chemistry" podcast shows you how chemistry ensures perfectly functioning products in all areas of life.
Just the Right Amount of FoamMar 19, 2019 | 6:08 min
In many countries around the globe, washing is still done by hand. People believe it ought to foam properly – because that’s supposed to be a sign of effective cleaning. Yet this foaming is a problem, since after washing, laundry has to be rinsed out many times until all of the foam disappears. This is why researchers at WACKER have developed a defoaming agent that only begins to take effect during rinsing, halving the amount of water used.
Say Goodbye to BitesJan 16, 2019 | 5:05 min
Insect bites are painful and itchy. They can even transmit diseases. Although there are a few substances that protect us from these bites, they soon evaporate, which means that they have no real effect. Thanks to WACKER’s cyclodextrins, however, it is possible to considerably increase the time that these substances remain effective. For instance, tests showed that they lasted for nine instead of six hours.
Mouthwateringly GoodJun 29, 2018 | 5:59 min
Chewing gum and chewy candy used to be two different worlds. Now, as part of the “Candy to Gum” project, WACKER is launching CAPIVA® C03, a ready-to-use compound for candy manufacturers. It allows manufacturers to offer a new candy treat that behaves like chewy candy in the mouth at first, but after a while an aromatic gum base provides a longer lasting sensation.
Ripe Mangoes Get a Protective CoatingSep 17, 2018 | 5:51 min
Mangoes are sensitive. At least a fifth of them spoil before they reach consumers in Europe or the US. That’s why the Dutch company Liquidseal has developed a protective coating for such fruit. A VAE dispersion is sprayed on the mangoes immediately after they’ve been picked. This soon dries to form an ultrathin film that prevents the fruit from spoiling so quickly.
Graffiti DefenseMay 02, 2018 | 8:52 min
Graffiti and stickers are a real headache for municipalities and railway operators. WACKER has now developed the first silicone-based product that protects bridges, underpasses and utility boxes from this kind of damage for a long time to come. Tests under real-life circumstances have shown that tough times are ahead for these wannabe artists.
From Stone Age to High TechMar 08, 2018 | 8:31 min
The Lascaux Cave - this richly painted World Heritage Site - is threatened with destruction due to visitors. For display in a new museum, the cave was therefore faithfully copied by a French company and painted by artists true to the Stone Age original. ELASTOSIL® M silicone from WACKER was used to make the molds.
Expanding the Bounds of BioplasticsJan 17, 2018 | 7:28 min
Crude oil is a finite resource. This is one of the reasons why the chemical industry is looking for new raw materials. Plastics can also be manufactured from plants, for example. However, these only become attractive when additives from WACKER’s VINNEX® product range are added. Only then are the properties of bioplastics as good as those of crude-oil-based materials. Processing problems can also be solved thanks to these additives.
Marriage of Wood and PlasticDec 06, 2017 | 7:28 min
They actually don’t like each other: wood is polar, while polymers such as polypropylene are non-polar. In order to process them into a homogeneous composite, they need a matchmaker: GENIOPLAST® from WACKER. Wood plastic composites are used to make interior trim for cars, for example. And Pinuform uses them to produce durable, easy-care decking boards, among other things.
And the Stain is GoneApr 19, 2017 | 6:06min
Fork lift trucks in the industrial warehouse, hospital beds in patient wards – these have a considerable effect on concrete floors. In addition to mechanical stress, over time the accumulating dirt also becomes a problem. WACKER now has a solution to both of these issues: the PRIMIS® SAF 9000 series, aqueous acrylate-based dispersions. They make flooring more resilient and dirt repellent and are also ideal additives to make washable wall paints.
Soft, Gentle and AbsorbentJan 17, 2017 | 6:04min
When you step out of the shower in the morning, you want to wrap yourself in a towel that is comfortably soft and that dries you off quickly. Treating the fabric with a new WACKER auxiliary is what makes that possible. When developing this product, researchers had to combine two conflicting requirements in a single product: while silicone fluids may make a fabric soft and fluffy, they are also water repellent. Listen to the solution that the developers came up with.
