Types of Screen Protectors

Tempered Glass

Tempered glass screen protectors are made from a strong and durable material that is designed to provide maximum protection for your device’s screen. They are composed of multiple layers, including an oleophobic coating to resist fingerprints and smudges, a tempered glass layer to absorb impact and prevent scratches, and a silicone adhesive layer for easy installation. Tempered glass protectors are known for their high clarity, smooth touch sensitivity, and edge-to-edge coverage.

PET Film

PET film screen protectors are made from a thin and flexible plastic material that is easy to apply and remove. They provide moderate protection against scratches and light impacts. PET film protectors have a clear and transparent appearance, allowing for high visibility and color accuracy. They also have a smooth surface that maintains the natural touch sensitivity of the device’s screen. However, PET film protectors may not offer the same level of shatter resistance as tempered glass.

TPU Film

TPU film screen protectors are made from a flexible and self-healing material called thermoplastic polyurethane (TPU). They offer excellent scratch resistance and impact protection without compromising on touch sensitivity. TPU film protectors are known for their long-lasting durability and high clarity. They are also easy to apply without any air bubbles and can be reapplied multiple times without losing their adhesive properties.

Liquid Screen Protectors

Liquid screen protectors are a unique alternative to traditional film or glass protectors. Instead of applying a physical layer, liquid protectors use a nano-coating that bonds with the device’s screen on a molecular level. This coating creates an invisible barrier that enhances the screen’s scratch resistance and repels fingerprints and smudges. Liquid screen protectors are easy to apply and provide a smooth and natural touch experience. However, they may not offer the same level of impact protection as tempered glass or TPU film protectors.

Choosing the Right Screen Protector
