For years, I thought pastry brushes were basically optional. I can put together a great batch of cookies, and sometimes a miso-chocolate tart, but I'm definitely not any kind of accomplished pastry chef. Yes, brushing egg wash over the top of an apple pie makes for a better-looking crust, but who could be bothered? Particularly when the pastry brush I had never quite managed to paint the egg wash on, so much as deposit it in gloppy strings. It took until the pastry section of the culinary program I took to realize that the problem wasn't the brushing, it was the brush.Get more news about Silicone Brush,you can vist our website!

What I had been using at home was a silicone pastry brush, picked up haphazardly at Bed, Bath & Beyond sometime in my first years after college. And though the silicone brush was admittedly easier to clean than the version with natural or nylon bristles, it also happened to be completely useless. A good pastry brush should work similarly to a paint brush. You are, in many cases, literally painting on an even coating of egg wash, or marinade, or sauce onto something you're cooking. A bad pastry brush, like the one I had, unevenly swirled bits of liquid onto a surface, leaving streaks and bald patches. You would be better off using your fingers.
I thought that maybe I just owned an especially bad silicone brush, but when I tried out other brands, they overwhelmingly had the same problem. Turns out, it's not the manufacturer, it's the material. The very qualities that make silicone a useful material in the kitchen-it's a non-porous material, and so food particles don't stick to it very well-makes it completely useless for a pastry brush, where you want the liquid you're dipping it in to cling. The very best silicone pastry brush I found was still much worse than using a regular boar-bristle brush. The most generous I can be to the category is that silicone pastry brushes are blunt instruments, better for slathering than carefully coating.

Once I actually picked up a few pastry brushes that worked-one nylon bristle and one boar bristle-I started using them all the time. Not only are they helpful for making actual pastry, they're great for quickly clearing your cutting board, or sweeping excess flour from a surface. The downside is that they're more difficult to clean, and that eventually they begin shedding bristles. But the good news is that they're cheap. At a restaurant supply store, you can pick up one for under $3, and at Sur La Table or Bed Bath & Beyond. If you're going to use a pastry brush, why not stick to the cheaper one that actually works?

Injection moulding liquid silicone rubber (LSR) has, historically, been the domain of specialist moulders. In spite of growing consumer demand, LSR is still seen by many as a difficult material to work with.
Now, a new partnership between German consultancy Das Kunststoff-Zentrum (The Plastics Center - also known as SKZ), Toolcraft (a machine tool manufacturer based in Georgensgmünd near Nürnberg, which also offers contract injection moulding services), and Munich-based injection moulding machine manufacturer KraussMaffei aims to improve the accessibility of LSR moulding.

SKZ is known for its capabilities in traditional thermoplastic processing. Going forward, however, cross-linking plastics such as LSR will play a more prominent role for SKZ. Professor Martin Bastian (Head of the Institute) and Georg Schwalme (Head of Injection Moulding) recently selected KraussMaffei as their technology partner for silicone processing.

KraussMaffei reports that the team at Toolcraft had made separate enquiries about processing LSR around the same time - and so the IMM manufacturer took the opportunity to connect all three groups.

It's not KraussMaffei's first mission to enlighten processors on the possibilities that come with mastering the technique. Last year, the group held a virtual event, dedicated to liquid silicone rubber processing. In one talk, experts acknowledged the challenges associated with fluctuating viscosities, which can lead to inconsistencies in part quality.
Using a reusable coffee cup lid, the KraussMaffei team, together with the mould maker ACH Solution, demonstrated the feasibility of moulding two different versions of the lid in one mould, and in one shot. KraussMaffei said its APC plus (adaptive process control) function is designed to deal with fluctuating material viscosities, with adaptive colour metering being one such solution.

LSR is especially popular in the medical sector. Another talk at last year's digital event focussed on the current trends in this market - and indeed, the first product to be created under the KraussMaffei-Toolcraft-SKZ collaboration will be a medical application with a part weight of 0.5 grams.

Ready to ditch your toilet brush? Sleek, new silicone brush options don't just look cooler than plastic-bristle brushes-they also promise an easier-to-clean and more germ-free experience. But do they live up to the hype? We have some good news, and it's based on science: Microbiologists agree that silicone brushes not only seem less gross than their plastic-bristled counterparts; they are actually more sanitary (and generally, a better buy) for a couple of reasons.Get more news about Silicone Brush,you can vist our website!

Jeremiah Johnson, PhD, assistant professor of microbiology at the University of Tennessee-Knoxville, says that silicone attracts fewer microorganisms (read: bad bacteria, including E. coli) than plastic because silicone is non-porous and resists the accumulation of organic matter from the toilet, which can attract germs.

"For this reason alone, silicone would be more resistant to microbial contamination," Johnson says. "That's why it's is being used more frequently in medical applications." Another plus: Because silicone dries much faster than plastic, it's also less likely to accumulate microbes.
Silicone is easier to clean
Silicone can also be more easily and thoroughly cleaned than plastic-bristled brushes, Johnson says, which obviously results in a more sanitary bathroom environment. For example, most silicones can be put in the dishwasher and even boiled (assuming the handle and other portions of the brush allow).
This would reduce the number of microorganisms present even further and is something you could not likely do with a traditional brush since plastics are particularly sensitive to chemicals and physical stress," he says.

SIlicone is more robust
Since silicone is generally resistant to more physical stress, including chemical cleaners and UV light, you could use stronger cleaners that would be more likely to kill harmful microorganisms present on the brush.

You'll also probably get a longer life out of a silicone brush than you would a traditional one because of these properties, which means making the switch is probably worth it (especially since silicone brushes tend to be a bit pricier compared to plastic ones).

But there's one downside
The only negative Johnson could find to silicone brushes is an environmental one: Silicone doesn't easily break down in the environment, and most curbside recycling programs do not accept post-consumer silicone-based products. That means when you're through with your silicone toilet brush, you will either need to take it to the landfill or find a specialized recycling facility on your own.
