Silicone protective film is mainly suitable for use on glass surface or high-gloss products, because it has the function of exhaust, and this protective film has better high temperature and low temperature resistance than acrylic glue, but the price is slightly higher. If the acrylic glue is scraped strongly, powder will fall off, and if the customer’s requirements are high, there will be residual glue. Silica gel does not produce bubbles, but it is easy to produce ghost images.

For example, the PET protective film used in large quantities for pasting screens requires silica gel, and the protective film of silica gel is better than Acrylic glue can withstand higher temperatures. Acrylic protective film is mainly used for packaging high-gloss products and as a membrane switch. This is a cheap and easy-to-use film.
