When buying an explosion-proof protective film, you must think about its clarity and transparency.

Explosion-proof membranes for car windows, especially those on both sides of the front row, should be selected with a transmittance above 85%.

Most of the keyboard explosion-proof protective film on the market, the protective film manufacturers are made of silica gel, and there are special ones, namely TPU.
