Covestro Makrolon Polycarbonate Flat Sheet offer high impact strength

Makrolon Polycarbonate products have a great blend of useful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering materials.
Polycarbonate is a very high quality material. Although it has tremendous impact-resistance, it has got a lower scratch-resistance and so a hard coating could be applied to polycarbonate eyewear lenses and polycarbonate exterior automotive components. The properties of polycarbonate are along the lines of those of common Acrylic materials, yet , polycarbonate is undoubtedly stronger, it is usable in a wider temperature range and is a bit more expensive. This plastic polymer is highly transparent to visible light and has better light transmission characteristics than several types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at high temperatures, generally above 80 °C (176 °F) to make strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic deformations without cracking or breaking. For that reason, it can be processed and formed   without needing to be heated using standard sheet metal techniques, for example forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are crucial, which can't be created from sheet metal. Remember that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and cannot be bent without heating.

The light weight of polycarbonate, compared to glass, has led to continuing development of electronic view screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink as well as LCD screens, though CRT, plasma screen and other LCD technologies generally still require glass for its higher melting temperature and the ability to be etched in finer detail.
Other kinds of items created from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and common style blender jars. Many toys and hobby items are manufactured from polycarbonate parts, e.g. fins, gyro mounts, and flybar locks for use with radio-controlled helicopters.
For use in applications subjected to weathering or UV-radiation, a special surface treatment could be needed. This either can be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that begins as a solid material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is heated until they melt. The melted liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.

Saving thousand dollars a year is THIS easy!

I am always in wonder at how some people complain about having no money.. and yet seem to have a blind spot on what they spend money on. Luckily for Mr Zhong Shanshan  (whom I bet you’ve never heard of!)  there are enough blind spotters in the world to make him the 6th richest man in the world.  How did that happen? Simple. He bet on people’s blind spot and sold them exactly what they never needed but suddenly though they did. Bottled water. Think about it. If you are 30 or over you still remember when you DIDNT see the need to buy bottled after. You drank water from your home tap. Then came the fear campaigns (and the chemicals!) that proved to you that water enclosed in a plastic sheath, and sold to you by a multinational was ‘better’. Yes, it may be better if it can be proven it is chemical free.. but the scores of cases already recorded of exposes of companies that just filled bottles with tap water makes that one hard to accept. And now we know about the problems of plastics and ...

GRAB THE BEST YOU DESERVE!

Hard Candy Vitamins are the best for you if you experience difficulty in swallowing pills and capsules. Capsules and pills usually contain certain nutrients that make them bitter and chalky to the taste.  That is why many people experience a hard time swallowing them. Some even have to drink water in large quantities to get them down. These issues are absent in the whole hard candy vitamin experience. These vitamins are fantastic in taste and go down very easily. The body requires a certain level of all vitamins and nutrients. They are salubrious and beneficial to the body and its functioning when present in the required amounts within the body. However, excess or increase in these levels can entail disastrous implications. It can even lead to toxicity or other sorts of deficiencies in the body if certain vitamins or nutrients exceed their required amount. This is the problem that most people face with normal vitamins. They either contain too much of a specific nutrient/vitamin or too ...
