Sheffield Plastics Polycarbonate Sheets are clear and tough

Makrolon Polycarbonate materials give you a balance of helpful features including high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is a very sturdy material. Even though it has tremendous impact-resistance, it has got reduced scratch-resistance and so a hard coating can be applied to polycarbonate eyewear and polycarbonate exterior automotive equipment. The properties relating to polycarbonate are similar those of Acrylic PMMA materials, except polycarbonate is going to be 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 many kinds of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at higher temperatures, generally above 80 °C (176 °F) to make strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo massive shape changes without breaking. For that reason, it may be processed and formed   at room temperature using standard sheet metal techniques, which include forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which can not be crafted from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and can't be bent with out a heating process.
Polycarbonate is frequently used in eye protection, along with other projectile-resistant see through or lighting applications that would normally indicate the use of glass, but require much greater impact-resistance. Many kinds of lenses are made of polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.

Lower Left Back Pain from Internal Organs

It is possible for left-sided back pain to be caused by a problem with one or more internal organs, such as from the kidney or colon. Several common internal causes of lower left back pain include: Kidney Stones.  Lower left back pain from a kidney stone may be felt when a stone moves inside the left kidney, or moves through the ureters, thin tubes connecting the kidneys to the bladder. Other symptoms include pain with urination, difficulty urinating despite a persistent need to do so, blood in the urine, and nausea and/or vomiting. Kidney Infection.  An infection in the left kidney can cause dull or intense lower left back pain. Kidney infections usually start in the urinary tract and bladder, and from there can spread to the kidneys, causing local inflammation and pain in the kidney. Additional symptoms may include fever, nausea and/or vomiting, and painful or stinging urination. Pain is typically felt next to the spine above the hip, and typically worsens with movement or pressure.
