Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
Plastic screen protectors cost less than glass and are thinner (around 0.1 mm (0.004 in) thick, compared to 0.3 to 0.5 mm (0.012 to 0.020 in) for glass) [2] and more flexible. At the same price, glass will resist scratches better than plastic, and feel more like the device's screen, though higher priced plastic protectors may be better than the ...
