Screen protector silicone film protects from damage during manufacturing or transportation. It prevent damage (Scratch, Strain) on Product such as smart phone window, Glass, PMMA, PC, Bezel. Urethane surface protection film, a silicone coated protection film used on ‘Surface Protection’ tape ((curved) touch screen/glass/PC/PMMA protector, blue tape). In addition, the product has a featured of high heat resistant and excellent wettability strength. Containing these features, it is easily adhere and peeled off and protects goods from any scratch & stain. Silicone adhesive polyester tape, a single sided transparent silicone adhesive film with hard-coated layer which protects any scratch on surface. The product is composed 3 distinct layers i.e. silicone adhesive + PET film & liner + hard-coated layer. It has great wettability means no air bubbles occur when the product is contacted with the surface.  PMMA is classified as a “thermoplastic” (as opposed to “thermoset”), and the name has to do with the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point (160 degrees Celsius in the case of Acrylic). A major useful attribute about thermoplastics is that they can be heated to their melting point, cooled, and reheated again without significant degradation. Instead of burning, thermoplastics like Acrylic liquefy, which allows them to be easily injection molded and then subsequently recycled. Poly(methyl methacrylate) (PMMA), also known as acrylic or acrylic glass as well as by the trade names Crylux, Plexiglas, Acrylite, Lucite, and Perspex among several others (see below), is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass. The same material can be used as a casting resin, in inks and coatings, and has many other uses.
