When you think of the screen protectors of old, you're probably thinking of TPU. TPU screen protector is a flexible plastic that's a huge hassle to install (it involves using a spray solution and squeegeeing out lots of bubbles), doesn't feel very smooth (thanks to its almost rubbery texture), and adds an "orange peel" type glare to your phone's screen. Still, it's flexible, so it can go edge-to-edge on any phone, it has better impact protection than PET, and it has limited "self-healing" powers for small scratches.http://www.yccscreenfilter.com..../tpu-screen-protecto

Because of its outstanding optical clarity, good performance properties, excellent printability, and ease of processing, films made of polycarbonate are chosen for a wide variety of applications. It is generally a good choice for high quality film products such as ID and security cards, graphic film products, reflective panels, LED/LCD display windows, and automotive dashboard and interior applications. http://www.teseidg.com/omay-pc....-film/other-industri

The Benefits of PETG Plastic

PETG is strong and cost-effective when compared to either acrylic or polycarbonate. Its unique characteristics make it preferable for impact-resistant glazing and high strength display units. Suitable for digital printing, PETG lends itself to product materials, displays, and signage. In general, PETG is a food-safe plastic that's commonly used for food containers and bottles for liquid beverages. Like acrylic and many other thermoplastics, PETG is fully recyclable.http://www.pvcpetsheet.com/pet....g-film-roll/transpar

The most advantages of tungsten carbide nibs are toughness and resistance to fracture, which depend on the tungsten powder grain size and amount of cobalt used .higher cobalt binder content results in more ductile die material with lower hardness and wear resistance . these dies are used to draw larger diameter wires with heavy reduction at slower speed without much loss in die life.http://www.natust.com/drawing-die/pcd-dies/

What is a Control Valve?

The control valve is an automated valve that can make precise adjustments to regulate and monitor any commodity flowing through a piping system. The function of a control valve is to provide throttling control in response to signals from a control system, using an actuator and a positioner. They are considered the "final control element" in an automated and usually very sophisticated "control loop".http://www.lozosevalve.com/str....aight-stroke-control
